I have an RX400h & an Iphone 3GS which work well together. Voice dialing might require a resort to the handset sometimes, but that's the only gripe I've had. Call quality is superb in this combo. I doubt apple has changed the Bluetooth hardware/software much to te Iphone 4, but a quick call to Apple's helpful tech support would clarify that.

OK, i'm an RX400h owner, so I have some insight, but please don't take my answers as definitive.

Can't answer the burning smell at all, but my guess is that if it were electrical or similar it would have showed up in 120 miles.

The suspension is not air, as per the RX300, it's simply coil springs - if the ride hasn't upset you I guess the loss of the complexity is a good thing!

The RX400h does make some odd ticking & whirring sounds at start up & shut down - took me a while to get used to it too. In the main it seems to be because all the stuff that's engine driven in an RX300 is electric driven in an RX400h.

Things like the power steering pump, the climate control - you'll no doubt have noticed that the engine doesn't star in the same way as your past RX300 too, all part of owning a Hybrid.

The pulling to the right could be down to something as simple as tyre pressures or tyre wear, so I'd start there, especially if there has already been a 4 wheel alignment.

Unless...... if it is only when you pull away under firm acceleration, because the RX400h is fundamentally front wheel drive & all that engine power causes something called "torque steer" which is down to the front tyres trying to put all that energy onto the road through only the front wheels.

Either way a reputable tyre company should be able to advise you if the tyres are at fault or not.

Hope that helps

There are a few, some may affect you some may not!

External mirrors can be a giveaway come resale time. Residual values on such far eastern imports are (with very few exceptions) dramatically lower than UK supplied vehicles. Not a problem if you plan to buy & run it 'til it drops, but otherwise beware.

The Harrier was never sold here, so any mechanical, electrical & trim/panel differences may have to be resolved via parts & advice from Japan.

I dare say there are specialists out there, so check on this before you buy.

I'm not sure about the radio, but if its like the USA item I once encountered the FM skips in 0.2 steps so a lot of European (inc UK) stations were missed because of this. Maybe a list of Japanese radio stations would show up the increments apart they use & guide you? Google I think!

Air bags, I have no idea, sorry.

Above all of that you should check if your car would have to undergo a full SVTA test before being legal (single vehicle type approval) similar to a kit car before it can be UK registered. Pan_european stuff is usually OK, but you're buying from further afield so this might apply. It checks everything you can think of, if the pain is hard, think of it as being a sure fire way to know if there's anything going to make your car dangerous. sadly reliability isn't included!

Me? I'd buy in the UK & avoid the potential problems, especially as the values of petrol SUV's is falling now due to pump prices.

The problem you have isn't the key, it's going to be something in the door locking mechanism in the door itself. It may even be as simple as a detached wire in the door.

As a fellow 400h owner I agree with your wife..... the 450h isn't as attractive a vehicle (so I'm sticking too). The 450 with the air springs (SEL up) has slightly better handling, but, based owners I've spoken to, no better fuel consumption! Despite the 40mpg claim.

Good luck!

OK, simple start.

I own a 400h, I see a regular 32mpg with only mild restraint. I have seen (holding back to 60mph) on a 250 mile run an amazing 37mpg! I have repeated that, so it is possible. Better though (once you get into the slightly different mindset of Hybrid driving) is the constant 28mpg around the city I live. I have a 1600 petrol Mini for such work & it can't better that.

Fuel will continue to rise in price, if only through artificial tax rises - another 5p per litre is going on early in 2012.

So, if mid 20's is OK with you buy a 350, the price difference will buy a lot of fuel.

The Hybrid stuff needs virtually zero care & in other parts of the world has substantially better warranties than here in the UK. That tells me two things, 1, even Lexus subscribes to rip off Britain, 2, they know more about the reliability than they will tell us - no manufacturer warrants something to last 100,000 miles unless they are damn sure it will do it!

The only downside of a 400h is the "initialisation battery" goes flat if the car is left standing for a couple of weeks - a booster box is needed to start, but not to turn over, the hybrid Battery does that! Weird!

As you correctly point out though depreciation is the killer & it's why there's such a large price difference on the forecourts atm. That will only get worse over time as Hybrids are being released by most major manufacturers. Ask yourself a simple question.

"If petrol goes through £1.50 per litre how many people will buy a large 3.5 petrol SUV?"

You see, the Lexus 350 is a great car - however, if you plan/need to sell one it's less great & that will get worse over then the next few years.

Sadly, with Hybrids, Electric cars, Range Extenders & soon Hydrogen powered vehicles coming out (even the next line in London Routemaster buses will be Range Extenders (a small petrol engine driving a generator only to charge the main batteries for the electric drive train) from 2012) the writing is on the wall for the large petrol engine.

Many moved to Diesel, Toyota offered Hybrid instead - more civilised! However CO2 & Fuel prices have determined that even though these are getting better every month the future will lie elsewhere - hydrogen probably (here's my new car, it goes like a bomb!). I wouldn't be an early adopter though, prices will fall, tech will improve & ownership quality will improve.

Ownership of either 350 or 400h will cost you at some point, but I guess if you worried deeply about either choice you wouldn't just "buy smart" you'd buy a Smart - probably Diesel too! :-)

If you mean the kit you have is the one socket for all functions, whereas caravans used to have the double socket set up, this the new EU standard & all new caravans are so equipped.

If the trailer etc has the old style pulgs you can either get adaptors or have the plugs changed. The new set up actually considered to be more robust & less prone to to random disconnections etc. Just make sure you keep the socket covered when not in use to prevent corrosion.

To be honest ..... I am a loss as to where to start, but here comes my best shot.

1). You don't mention any braking loss, or strange sensations through the pedal. For such a catastophic failure I would have expect more than an alarm & a light on the dashboard.

2). The local garage would have spotted a blow or leaking steering pipes when they checked out the brakes.

3). (With the utmost respect - you say you're "a dumb blonde"!) I think you might have been seen on your way in .... if you follow my drift, it is a question of who you beleive, & the faith you place with them.

4). Are you a member of the RAC or the AA? If so I'd use their independent technical team to a) check the vehicle over & give you a written report as to the nature & probable cost of repairs. This will cost, but in the face of yoursituation you need an expert on side - if only for peace of mind.

I'd call the repairing agent & tell them you wish to drive the car away from their premises asap & that you require a written estimate for the repairs, which should be itemised & the time required broken down into stages so you can understand (or rather you appointed mechanic can understand) exactly what the situation you face is.

At the same time as requesting that lot I'd make them aware you intend to have the vehicle independantly expected & an engineer's report prepared for comparision.

DO NOT tell the Lexus agent who will be preparing that report, it is not their concnern & you need to protect your interests.

5). Do not give up hope, their are many independants who will probably be able to fix your car for substainly less than the £5K+ quoted.

6). once you have the estimate, the local garage's point of view & (if ordered) an independant engineer's report you'll know instinctively the best course forward. However, if the independant report varies wildly for the Lexus dealer's claim I'd point the whole lot at Trading Standards & claim any bill they charge you & the cost of the report back, plus another good sized lump for the upset & inconvenince caused.

Hope this helps open some options, be aware, Lexus main dealers, like all their kind whatever the brand badge on the car's nose, are much mre expensive than other options in the vast majority of cases.

It is possible that you have a Battery that is on it's way out. So before you do anything else I'd get that checked out.

It is a known issue with the RX400h that the Battery is rather undersized, resulting in a flat Battery if the vehicle is left standing for around 10 days to a fortnight.

This is because the Battery is only to initialise the car's systems & to provide a supply for the alarm etc when the car isn't running.

The main power all comes off the Hybrid cell, or via the enigine driven systems when that is low.

So, assuming the Battery is OK & you have longish standing periods, such as at an airport, the up side is that you don't need a starter from a 3 litre motor.

I Have to leave mine at an airport for trips overseas & having had to use the Lexus callout service twice took to having a jump starter in the boot ready for my return.

I have a Hilka unit which works well, although I sure many other would do just a good a job.

Be aware of the following points though.

Tha Battery is under a cover that needs a small screwdriver to press the centre to release the clips. These can snap if you not careful refitting them, so either learn before you leave home or at least carry a couple of spares - they can get lost as well.

I would not recommend simply leaving the cover off under any circumstances, or trying without the clips.

The leads of a starter box are short, to ensure full current transfer. So you should find one with the longest leads possible. You'll always need to find somewhere under the bonnet to safely rest the unit while you start the car.

Once the car is running, all the starter will do is activate everything & allow the beep to show the car is "ready" - but wait until the engine is actually running before you disconnect & return the cover back over the Battery - a good tip is to turn the heater up high while you pack everything away. This encourages the engine to keep running & charge the Battery, because it's being told that you need heat & that only comes from a hot engine.

If the engine switches off while you are packing you kit away don't panic. It will restart off the Hybrid battry once the first initialisation has been carried out. The display will (should) still show "ready" to confirm this. If it doesn't you have a bigger problem than a Battery.

Once moving 15 minutes or so of constant engine power will recharge the Battery - unless the lights etc are on, in which case you might need 25 -30 minutes to be sure.

Hi there, first time poster.

I am looking at buying a 2006 RX400h and have a couple of questions.

Firstly i have just trawled through the last 10 pages of threads, looking at MPG results to get an idea what its going to cost me.

I cant find any that show how many miles per tank you get.

My current car is a 2005 Saab 9-3 1.9TiD, it costs me £65 to fill the tank and i get about 450 miles. The computer shows 50mpg.

Of course i dont expect the Lexus to be anywhere near this, but would like an idea off as many people as i can to get an average miles per tank.

My daily commute is around 50 miles or 'mainly' national speed limits.

Secondly, the Lexus shows to have a MPG of around the low-mid 30's, but surely if its running on batteries around town this cant be included (battery power wouldnt show as MPG). So does the MPG only come into effect when using the petrol engine itself? So say you do 5 miles on battery and 5 miles on engine then the car should only use 5 miles on engine to work out an average. Or am i completely off the mark?

Completley off the mark! ;-)

The mpg for any vehicle is reached by the number of miles traveled campared to the amount of fuel used. For example, your Saab will almost certainly shut off the the fuel flow when you lift off the power for deceleration. It was emissions rules that brought this in for new cars a few years back & was the down fall of the carburettor ... but I digress .... those moments of travel are included, just as Battery driven, or Battery assisted miles are in a Hybrid.

Thhe low 30's is about right, although you have to be mindful of the fact that you've got a large 3300cc petrol V6 in the nose, not a 1900 TD.

The secret is to adapt your driving style, foot off the power (not feathered) when you lift off, lighter pedal pressures (remember these RX's can shift, 60 can come up in circa 7 seconds if you need it) so what might seem like next to no input in an RX will equate to a firm prod in the Saab.

They are very differnt machines & you really must drive a couple of RX Hybrid's before you buy - the trade off is much greater civility inside & the regal feel you have in car parks as you cruise past people in silence (then run them over because theyaren't looking out for cars - they're listening! :-) ), or in traffic jams, when you use little to no fuel, whilst everyone around you is idling their fuel down the exhaust.

As a real world insight, I don't hang about (much!) & get 28mpg around the local city, 32-33 on a sensible (ish) run & with a light foot to Lincolnshire (a full day out) I saw 37mpg a couple of times with a genuine, compared at the pumps fill to fill, 35 for the full trip.

Now I don't know what you expect, but for a large SUV with over 3 litres of petrol power I think that's pretty fair - friends have "other brands" with Derv motors & most struglle to get within 10mpg of those figures & the best (BMW) can't better them in the real world.

Hello everyone - I am the very proud owner of a 2008 RX400h and this is my first post so please be gentle !

I tried the search engine, but could not find what I was looking for.

I want to fit a detachable tow bar to my car to tow a caravan. Have no issues with the mechanical bit, but need to know if there is a plug in the wiring loom that you can just plug the towbar electrics into, and is such an electrical cable with the correct loom plug available from a Lexus dealer (anyone know the part number?)

Also another question but not Lexus related. Do you have to have twin electrics to tow a caravan, or can you get away with a single electics setup.

Thanks very much to anyone who replies.

Regards

Ed

Hi Ed, I went through a similar set of questions when I bought my 2008 400h.

I don't think there is a seperate plug for the electrics, I did get very clear advice that fitting a bar to this model is very much a specialist job though, in part due to this very point. All to do with multiplex wiring & ensuring the power stays up when the engine switches off - & remeber this car doesn't have an alternator, it controls things in a different way.

As you will no doubt know, the Lexus bar has a fixed ball, well placed for shins! There is a removable ball option from Witter & this can be sourced through them or Towtal who can do the fit as well.

All types require a cutaway in the bottom of the bumper.

Be aware though, if your caravan is an older model with a blade type stabaliser you'll find this may be a problem with the removable ball type bar. If that isn't a problem make sure the ball is cleaned of the customary black paint befire using it with a friction (pads in the hitch) type stabiliser or you'll have other problems.

Check the nose weight applicable, I think the removable type has a higher rating.

In theory you can get away with a single socket for the electircs. However you probably wouldn't be wise to to do do, as the second socket provides power to the fridge & charges the caravan Battery (which keeps loads of stuff happy that are a pig to reset if the Battery voltage drops.

If it's the sight of 2 sockets that's the issues (even if it isn't really!) I'd go for a single Euro multipin socket which covers all bases in one, is becoming the standard (already standard on all new caravans) as this is less likey to drop connections & if your caravan has the old twin plug setup there's adaptors on the shelf if you don't convert that end.

Anyway, enough rambling ....... I'd get the plastic cards out, bite the bullet & have a pro job done, at least you'll have someone to blame & pay for any issues later! ;-)

Hello all i am in the process of getting a lexus RX400h se with 99k on an 06 plate full lexus history absolutely mint condition. Whats to look out for and what would i be looking to get mpg realistically.

These things seem to be as relaible as a Swiss watch!

Only 2 things to be aware of as far as I can tell. 1) Check the mapping discs for Sat-Nav, a good dealer will throw them in as part of the deal. 2) They don't like being left standing for long periods because the Battery is quite small & doesn't start the engine, it only initialises the systems that start everything. The baattery can go down in 10 days if you don't go anywhwere & needs about 15 minutes driving to ensure it's charged again.

In other posts you'll see I'm looking into options for this latter point & so far I've found a larger Battery that might (it is VERY close in dimensions) fit, but need to ascertain if it really does fit & what the implications are as far as routine driving/charging is concnered.

Solar charging seems to be the best route, but you'll need an extra direct wired socket under the dash because all the Lexus one's are off when the ignition is off.

As to fuel consumption................ ummmmmmmmm....... How heavy is your right foot?

If you drive hard all the time, using engine power, rather than the Hybrid system you'll get high 20's as a braod idea.

However, as you are buying a Hybrid my guess is you'll be in the mind for a little restraint & behavioural change. You won't lose much in journey times (trust me!), but you will save fuel.

Tips: when you slow down get right off the acccelerator, the engine stops & re-gen of the Hybrid cell starts - there's a large motorway hill near me & it is kind of cool to sail down with the electric motors holding you back in re-gen mode & the fuel readout reading 99.9mpg! All at 70mph (honest judge!).

Accelerate lightly & you'll fone the electric motors assist the petrol engine, rather than a full bore shove & getting below 10mpg al the way.

In all I get around 28mpg around town & 32-34 on most longer runs. I have seen a genuine (verified by top to top refills fo the tank) 37mpg, but that does take real discipline - I have firneds with 1.6 engined hatchbacks that just about manage 40mpg on a run & 22- 24 around town, so, for a 3.3 litre SUV the figures stack up. (I have a collegue who bought a RR Sport Diesel within weeks of my Lexus purchase & he gets around........ do you really want to go there? OK ...... 23 mpg at best!

Hope these ramblings help .... good luck..... enjoy!

On the the dashboard there's a swith named AUTO for the system, directly below that is a switch named OFF, press that & the system is off while you drive with windows, sunroof etc open - no point in freezing the world..... If you turn the system off when you leave the car it won't fire up when you start up. Alternatively, for the more demanding, press the CLIMATE button below the map screen & you can configure the system to suit your needs, temp, airflow, fan speed (which I suspect is the real reason for your question as it can be full on under Auto, & even if the aircon is running or not. Problem solved? Maybe not! A solution to make it workable? Probably!

I am feeling a bit thick over this as I updated the sat nav in my Mk 1 RX300.

Where does the sat nav disk hide in the RX400h? As part of the deal in buying the car the dealer are suggesting that there isnt an update. But as the car is an 07 plate I find it hard to believe and want to check on the map update site.

All advice gratfully received.

The DVD unit for the sat-nav is in the boot, forward most compartment on the right, it faces towards the front & is hidden under a cover.... probably explains your dealer's retisence, they probably can't find it either! ;-)

I note you are having a towbar fitted, do you plan to have the fixed bar (as per Lexus) or the alternative from Witter which has a removable towball (&, I think, a higher noseweight). I be grateful for your experiences on this when it's done.

Forgot to add the third possible option .....!!!! Ooooppss!

When (IF!) I find the above works I'll approach Lexus with a clear line of how to fix it..... after all they probably only go for the batteries Toyota stock & even the new Prius has a solar roof option (for entirely differnet reasons .... maybe they missed a trick? Maybe I need to contact the Patents Office in short order!).

In the ned they will find it harder to reject claims if someone has proved a solution works ......

"Fit for purpose" as in the Sale of Goods Act comes to mind ....... any car that fails on something as basic as a repeatedly flat Battery could weel be failing under that criteria.

In light of this problem I am taking 2 (with a possible third later) route towards a solution.

1. A larger Battery must exist somewhere, if not in physical dimensions, surely in terms of a better amp/hr rating.

Now before everyone jumps up & down with joy there may be downsides to this. a) Warranty, always a b***er when you resort to non standard kit! For my part I'd argue this through to the High Court if penalised, the voltage remains the same & the extra capacity stays in the Battery & doesn't feed extra current into the system.

However it might weel extend airport park ups & similar by a measurable amount, because the voltage won't go critical so quickly.

2. If you only do short(ish) trips most of the time you won't achieve anything with the above in the long run because the Battery will take long to charge as you drive ...... eventually you could kill the Battery through lack of charge.

So ................... Solar charging to keep the power up no matter what. I;ve used these things with my motorhome to amazing affect, a 90amp/hr Battery dropped to 50% overnight through use can be restored to health through a 90watt panel. Now thats extreme, so a 5watt (ish) panel should do the job one most days. Bear in mind even a street light can give a small amount of power through a solar panel. The principal isn't a constant charge, more a varying charge dependant on light .... so a shaded parking spot might need a bigger panel to gather enough light to be effective.

These can be bought for about £30, less than a replacement Battery.

However it will require a seperate in car socket with a feed to the Battery, to modify one of the Lexus dash fitted ones would be unwise (& a warranty issue for those so affected) ..... unless the one on the boot is constantly powered............

IMPORTANT!!!!!! If you decide to follow this route independently make sure you fit or have inclded in the solar panel a blocking diode or a supply controller. If you don't you can lose power back to the panel .... not a good idea.

If anyone's interested I'll post my findings as & when I have them.

Of course the real answer might be both at the same time .............. as J. Clarkson would put it ......POWEEEEERRRRRRRRRRR!

When I'm accelerating passing another car my automatic box seems to be slipping, just like the feeling of a slipping clutch on a manual gearbox. Any ideas, anyone? It seems to over-rev before picking up speed. Is this normal? I've only had the car about 5 weeks and I'm not absolutely 'au fait' with how it should feel. Thanks Chris.

The experience you describe is "normal" on a 400h, due to the use of a CVT (constant velocity transmission), rather than a regular torque converter type gearbox.

I'll try to keep this simple!

Instead of "gears" there are two pulleys through which runs a steel belt. Each pulley can expand or shrink it's diameter. So at low speed the engine pulley is small & the drive one is large to give the engine (or front electric motor) the appropriate "gearing" to move the car. At higher speeds the ratio is reversed, the engine pulley is large, the drive large, to generate the effect of a high gear. (A look at the way a bicycle with derailier gears will make this easier to understand).

In effect you have one infinately variable gear.

When you accelerate the load causes the ratio to shift back towards a low speed setup (but not that far) to allow the engine to maximise it's power delivery. Although it sounds like the engine is over revving or (as you descibe) the clutch is slipping what is actually happening is the engine is deivering the power you demand as a constant & the transmission is seemlessly adjusting to match that to the road speed as you accelerate.

Yes, it does sound odd, but it is very affective because with not steps in the power delivery to change gear you have constant smooth acceleration, which only relents when you ease off the power.

It requires a different technique to get the best from & practice is the only way I'm afraid! Much like gaining great mpg figures from the Hybrid drive chain as a whole, the more you give, rather than demand, the higher the returns.

This explantion is, I hope, sufficient to make things a little clearer! It also highlights two more small items.

1. Why there is a power meter instead of a rev counter. The latter would be pointless, over revving is impossble because the CVT & management electronics prevent this, the maximum rev points for power & torque are unenccessary because there isn't any gears to require them as gear change points & in this setup knowing how much power you are pushing through the transmission is of more value.

2. The B setting on the gear shift. Because in a Hybrid the engine shuts down in over run mode you don't have it available as engine braking when descending hills. If needed this can be restored by selecting B & thereby over ruling the engine's normal shut down mode & allowing it to provide some retardation, although this may not be as much as with a regular gearbox/torque converter.

There you go ........ now where did I put those asprin tablets...... it's amazing how much your brain just does when driving..........

This Battery issue is well known by the AA & the RAC. My own lexus agent has told me that there is a problem (that has been fixed on the new RX450h) the, basically speaking, allows the charging system on the car to fool itself as to the charging state/cycle of the RX400h.

I've had a new Battery & the rescue services have been out 3 times due to this issue.

So far I've been unable to find a larger capacity Battery to replace the Lexus original.

There isn't a fix available from Lexus, although there should be & in light of the number of stranded owners they really should be thinking about this as (from my limited feedback) it seems to be a software issue, rather than anything mechanical.

The Battery itself only initalises the car's systems, the actual starting is off the Hybrid Battery, hence it's small size.

I am looking into a solar charger as a stop gap, although you need to understand things like how to get a seperate feed through the car (the accessory sockets inside are both dead when the ignition is off, rulling out this way back) & the need for a blocking diode to prevent the panel itself discharging the Battery. It is also fair to point out that the need for light, even a street light at night can provide a limited amount of power, & that this option may not provide a "solution" as such, more a staving off of the power drain, because..........

........ the bottom line is that the Lexus Battery isn't of sufficient capacity for the car to be left parked for a couple of weeks without use to keep it charged.

If any other owners have had similar problems please add your experiences to this mail. If there are enough of us we MAY be able to persaude Lexus to develop a solution, rather than let the word spread through their dealers & the roadside services the the RX 400h has an issue that needs a fix, not a recovery truck.

A solution is, in light of the recent Toyota publicity, in everyone's mutual interest - after all, how do we know if this is an RX issue, or a general Toyota Hybrid issue that affects all but the latest generation cars?

My wife has a rx300 and just wondering if you can switch off the 4wd? Closest it actually get to off road is going on the drive of a night! Would there be any mpg savings to be made from doing it?

Unfortunately not, the 4X4 system on an RX300 is permenantly engaged. Yes, there would be huge fuel savings if that were possuble! :-( The alternative is to follow me into an RX450h, but then you'd have to weight the purchase costs against the fuel savings. In UK mpg terms my Hybrid is regularly giving 32-34 mpg, consistant 28 around the city & have seen as high as 37mpg on a few long runs. That said if you use all the performance all the time it is easy to get down to 24-25! ;-)

I have just purchased from the states a performance chip that is specific to the RX400H. They say that in no way will it affect Lexus warranties and could improve MPG by up to 15% and performance as well. When I asked about fitting it, they implied that anyone who could hold a screwdriver and a pair of pliers would be capable of doing the job.This was really cheap, 25 dollars with free dispatch to UK. Now having my doubts. Any thoughts?

Over the last few years I've seen friends try these chips on numerous different marques/models with varying results.

On Diesels they can provide some improvement, but the petrol options seem to be succesful on the economy front. If you look in the motoring press you'll see there are now two kinds for Diesels, one for power, one for economy. Now if the originals from the same supplier offered both why do they need two varieties now? Bottom line, you can have performance OR economy, not both. Even a Diesel miser such as a VW Bluemotion will gobble fuel if you go pedal to the metal everywhere.

I'd take the quote of the chip offered not affecting Lexus warranties with a HUGE pinch of salt! First the USA warranties are different to the UK's (WHY?) & second if it's true a Lexus agent will be able to confirm it with a phone call.

Any problems you have will fall back on the chip supplier & (speaking as vehicle importer) you will very quickly find that the warrnties they supply will be subject to USA law & therefore not applicable here, leaving with the choice of footing the bill, trying to persaude Lexus that the chip wasn't the cause of the problem or litigation in the USA.....

Finally, there's an old adage, "it it seems to be too good to be true, it probably is"!

Hi, does anyone have any information on RX400h LPG conversion, I have looked into the idea and am getting close to adding this to my 56 plate. The supplier concerned is of good repute and experience with great workshops etc at the same time he is convinced that this is a straightforward job. The cost should sit around £1800 and will pay for itself in the first year at my current mileage of 30k per yr. hardly suprising when the price of LPG is 50% of petrol. Any thoughts folks?

I looked into this a while back & came away with the conclusion that it wasn't as easy as it sounds & probably problematic on a Hybrid. The reason is simple, each time the engine starts it has to run on petorl first & then switch to LPG. As you know, even on long runs down the motorway, the engine switches on & off as required & most of the time you aren't even aware of it, so unless you have an automatic system to work with the Hybrid controls you may well run into problems. Personally I'd seek the advice of Lexus technicians before you spend £1800, because the Hybrid parts of a 56 plate will still be under warranty & engine rebuilds are VERY expensive, probably more than the LPG conversion due to high labour rates.

All that said if you have a wonder-system that does work let us know, for some, as you observe, the cost (& loss of the spare wheel?) may well be worth considering.

I have experienced a similar braking sensation with my RX400h. Until now I have been told & therefore assumed, it was an idiosyncratic sensation of the hybrid system.

It has never been dangerous &, in my case, not really seasonal.

It is however there & most obvious under gentle braking. I can best describe it as being akin to the hybrid re-generation being cut (which it does at about 3mph)& therefore requiring more input on the brakes to maintain braking effect.

Fuel consumption will be higher in the winter months, due to the need for the engine to run more to keep the heater warm & the hybrid Battery charged (it powers pretty much everything in the car, not just the electric motors) & the extra use of heated rear window, fans, heated mirrors, etc. To be fair this is something that affects every car on the market, the difference being that they (mostly) supply power of an engine driven alternator, not a hugely capable Battery.

As to the dealers' attitude.......... Lexus don't want it widely publicised & won't admit to it, but there are some dealers are definately not up to the standard that Lexus would have the public believe.

Not surprising really, we are talking about the car retail industry, an industry that has had a very poor image for many years.

I had some very serious issues with my local dealer & ended up using another some 35 miles away. Lexus (Belinda Poole herself) simply washed their hands of the issues & said it was between me & the dealer. Lexus Europe backed her up.

In my case it back fired big time for Lexus. 8 months later I was in control of a pan-European budget for a loan car fleet for a luxury leisure group, net result, 45 BMW 1 & 3 series ordered & the previous Toyota fleet thrown out. Thus far no problems & support equal, if not better to that from Toyota/Lexus (who were in the running until the day I was appointed!)

So I would approach another dealer & explain the problems you are having with the car, without winding yourself up over the selling agent in the process - this alternative dealer should be part of the solution, not part of the problem.

If you are still unhappy you do have the option of seeking an independant engineer's report. However, a word of caution. Before you go that way return the vehicle to the supplier & state that you want them to check the systems out thouroughly & give you their written evalution as to the state of the vehicle's systems.

If they refuse or if they find nothing you should then advise them in writing that you intend to seek an independant engineer to inspect the vehicle & should they find anything wrong you will seek redress for the cost of that report together with an appropriate sum for compensation due to their inadequacies.

Hopefully it won't come to that. But never assume that a dealer's word is gold. If they supply you with a print out showing nothing is wrong then they have given you their position in writing. The next move is yours.

Do everyone a favour though. If you find there are issues with the car &/or the dealer, post that info as widely as you can. Sadly Toyota/Lexus have a very slow witted means of handling problems, often preferring the "it'll go away" approach.

America has made you concerned & rightly so. Because the problem was/is quite serious in potential. But, what really did the damage to Toyota was the way the problem & associated concerns & publicity was handled. Hopefully they have learnt, an opportunity never goes away, it just goes somewhere else, but I wouldn't bet on it.

Hi

I have owned a 52 Mark 1 for the last year with no issues, however now the engine will not start. THere is a clicking noise, the display screen flickers and the engine does not turn over, the fan and radio work however?

thanks

Flat Battery (could be dying) or a sticking starter motor - I doubt it will be anything else.

For the former, try jump starting, if the Battery on the vehicle is slightly down on power (or if it has a dead cell) this will be overcome to allow you to start.

In this instance I would change the Battery asap, rather than being left stranded.

If that doesn't work you need tow people, one to turn the key & the other to tap the starter motor with a hammer (not TAP, not bl**dy great whack!), if it starts you could be in for a new starter motor soon (keep the hammer handy in case it sticks again.

Unfortunatley, being an auto, you can't rock the car in gear for the last option.

Good Luck!

Hi

I have managed to loose the master key, and the Lexus dealer is saying it will cost you £1000 as they can't program another key without the master, I have the valet key. Has anyone else ever lost the master key and what did you do :(

Hi,

Haven't used these myself, maybe someone else has? But it has to be worth an enquiry.

This kind of service is more common in the U.S., so it can be done, but I'd be sure to check EVERYTHING, including getting a couple of previous satisfied Lexus customers before you let them loose.

This is a very highly publised issue with Lexus & Toyota, a case of owner beware I guess, my keys live on a chain to my belt when I'm out, just to be sure - that won't stop me sitting on them & breaking a master though...... ummmm ...... errrrr.... back to the drawing board! :-(

Good Luck! Let us know how you get on though!

Hi,

The engine+VSC warning lights illuminated on my RX300 couple weeks ago. The car continues to drive just fine.

Lexus in Leeds say the problem is with a sensor on the exhaust manifold - a Bank 1 Sensor 1 fault. It'll cost £300+ to fix. It seems odd that an exhaust sensor problem would illuminate the VSC light but they say the VSC light is used to warn of several problems and not just VSC issues.

Has anyone else experienced this?

btw, this is the first fault on my RX in 8 years!

Thanks.

Don't know if this like a lamda sensor (part of the emissions kit) or not, but if it is it could be that it's just fouled up with exhaust particles. For a lamda sensor a good full throtle blast through the gears often clears it out, it seems that these don't like lots of low speed cooler running, as everything seems to running OK I'd be suspicious of a large bill when it could be that simple.

Maybe it needs removing & cleaning in something like solvent or petrol? It could even be that the sensor is OK & it's wiring falut, somthing like a dry solder joint that's finally given up.

Makes you wonder what vital function that senor does if everything works OK though, doesn't it ?

Greetings all, i'm soon to become the proud new owner of a Tungsten mist Rx300 SE-l . In chosing what to buy I considered other alternatives such as X3's, X5's, Freelanders but always came back to an RX300 as it seems to tick all the right boxes. The cars being sold as an approved used car at Lexus Reading, my only concern are the tyres. The fronts were badly worn on the inside & outside edges so I negociated replacements as part of the final price, The two rears are just under 3mm all over & would only take me a few months of driving before thay also need replacing, despite this being an mot pass should the garage replace them before selling the car? Also the 60k service is due in Jan10 so together with the cost of tyres I am looking at spending another £800 in the next four months...

I always advise anyone looking to buy a vehicle to negotiate, negotiate hard & if you can't secure a deal you feel 100% comfortable with walk away, there are plenty of other like vehicles to choose from.

Right now that advice has never been more relevant. The current defecit of customers for dealers will change, maybe by next year, but right now they need you more than you need them (sadly not many realise that enough!)

If you've signed the sale agreement & paid your deposit (or agreed a part-ex) then that's it, deal done, you've commited to a contract.

You could try & negotiate a fair deal on the outstanding items, rear tyres & service at a discount, but if they say "no" then there's little you can do except shop around & take that business elsewhere when the time comes.

At 3mm the rear tyres would pass an MOT with an advisory notice to keep an eye on them & consider changing them soon.

The front tyres, seems the car has been driven with them under pressure (rather than over) as this wear pattern is typical of such use (abuse?).

The service schedule (like the rear tyres) are largely down to your annual milage/use. The dealer could argue that a lower mileage user might not encounter that cost for a longer term. In any event you are talking 30% of a year until then, so a discounted service seems the fair proposal to me.

In the end it's the dealers' job to keep you happy & your responsibility to make sure your purchase meets your needs & expectations. A balance has to be struck.

As at the top, if the deal's done you have to live with it, or hope for a negotiated better offer.

If it hasn't then I'd suggest going for 4 new tyres & a discounted service in 2010, confirmed in writing. Of course that service can only cover the actual items in the schedule, anything over & above that would be down to you.

If the dealer won't play ball, walk away (no salesman will let a promising sale walk away if there's a remote chance he'll strike the deal) & look around other dealerships.

After all, the hard part is done, you've choosen the car & set the specifications in your mind. And, at the current tax bills, a full petrol RX won't walk off a dealer's forecourt everyday, so you are in a strong position to hunt around - good luck!
