  1. Excellent point. Yes, once the deep cycle battery runs down and the cells aren't able to take a recharge then the main engine will have to run more continuously in order to try and charge the battery. Once it gets down below a certain voltage I understand that it will throw a fault code and may affect some other functions too (not least of which is non-starting!). It is meant to be replaced with a deep cycle sealed battery (VGR/gelmat type) or sealed L/A equivalent. Normal automotive car batteries aren't designed to be continuously be deep discharged and may not last long under that duty, although they'll get you out of a hole short term.
  2. I think that you can replace this with any deep cycle battery of a suitable duty. Later models used a 12V 110AH deep cycle VGA type battery located under the rear boot lining on the LHS. Yours may be the same type. They're not cheap but there are some sealed L/A equivalents for much less. Don't use a high current short term discharge cranking battery (ie normal car battery) as this won't be up to the job and isn't designed for repeated deep discharge. Basically any deep cycle equivalent will do. It doesn't have the be the Panasonic battery that Lexus use.
  3. Just as a footnote, the correct battery is not the normal 12v battery. It's a deep cycle battery so needs to be replaced with the same specification replacement. This isn't the same thing as a typical automotive cranking battery which doesn't use much of it's charge when providing short, high current bursts to the starter motor circuit. Deep cycle batteries are designed for regular and prolonged full discharge and recharging...normal batteries are not so wouldn't last long in the RX450h if used for this purpose. Deep cycle batteries are more expensive than automotive cranking batteries. Here's a link I posted on another thread to a suitable replacement example: Suitable Battery replacement for RX450h This isn't sold as a sealed battery though I think it might be. I have a feeling that my last one was a sealed L/A version. For and AGM alternative there is this which is still £100 cheaper than Lexus prices and will last longer than the lead acid equivalent: https://www.batterymegastore.co.uk/12v-110ah-agm-deep-cycle-batt-bat412101084.html
  4. Gosh Herbie, I thought full postcode came in late noughties with Lexus? My old GS didn't have it (2007) but the RX I have does have it. Have to agree about fine tuning with the mouse. I find it better than fumbling with touch screens but when you want to make small movements it can be infuriating. We'll probably be told that we shouldn't play with it whilst on the move but sometimes there's no choice if you have to come from one screen to another. I agree that the Lexus system is over complicated and unreliable. I don't have many in-house systems to compare it to except our current Honda which I think is based on a simplified Garmin system. Easier to use but less information on tap. One thing I ignore completely is the "live" traffic information on the Lexus one. It can be over a day out of date! I travelled to Cornwall last spring and whilst near Taunton, it was telling me to leave the motorway and take the scenic route due to delays ahead. It also pinged up that there were delays on the A30 (due to roadworks). I ignored it and had a trouble free trip with no delays. The A30 roadworks had finished the day before and the M5 accident had been cleared hours earlier. It's just a rubbish system. Conversely the Garmin stand alone uses bunched up cell phone signals to determine congestion ahead and is usually very reliable. If it says 5 minute delay, then that's usually what you find. Tom-Tom have the best system though which allows editing way-points on the fly without trying to redirect you back to one missed (it simply recalculates for you to the next point).
  5. Great result! I can't understand why no new matching wheels are available for a 4 yr old car. Surely they must keep some stocks....was it the 19 inch wheels you have? Had a cloase look at mine (a year newer) and they look fine except for a scratch on one from me stupidly using a wheel cleaning brush when washing it a while back. Lesson learned. I never use brushes on wheels now.
  6. Yes, its amazing how easy it is to get disorientated. Mind you a few drivers this morning drove me nuts. One decided that she didn't want to turn off the road into a car park to wait for someone she was picking up, and promptly parked her car in the middle of the main road through town at some pedestrian lights blocking the road for everyone else. A brainless family, led by "dad" then stepped out 20ft in front of us without looking (they were only 20 yds from the same pedestrian crossing!) and I thought for a moment even at 10mph, I was going to lock up and take them all out as they looked around and just stood there! A few choice words of advice were given! Another parked across the turning into where we live to make a phone call, engine running, and partially blocked the whole turning. Some people shouldn't be allowed out behind the wheel this weather. Roads are seldom so bad (unless it's hard packed ice) that it prevents a competent driver getting about here in the South West. It's always the drivers who haven't a clue how to drive in these conditions that cause the problems. If they lack that much confidence or are that inept then they shouldn't be out and about creating unnecessary hazards for those who are competent and careful.
  7. Why though would anyone want to pay such a sum to Lexus when a first rate off the shelf satnav (even ones with dashcams built in these days) can be had for less money? Most after market units are likely to be less unwieldy in use than the Lexus system which I just haven't found to be that reliable. It doesn't matter what price the car was new. The map data to be provided is hardly an expensive software development exercise...you already have the software installed in the system, and are only asking for a map update. To argue that "it costs what it does because the car is a premium product" is an illogical arguement and makes no sense when you look at the technicalities of providing the update. To charge what they do is daylight robbery. I can update my Garmin by plugging it into the PC and selecting the update I want. I then leave it to do its thing. My involvement is 5 minutes tops. It may be a little more with a new dvd installation but we're not talking an hour, or even half an hour to press the buttons and follow the instructions. On the on-board system, every time I've wanted to navigate to somewhere in Bristol for example, it shows a route which takes you round the houses for no apparent reason. I wanted to find a commercial premises near Cribbs causeway a few months back and instead of directing me off the M5 at J17 (CRibbs turn-off) it wanted me to come off much earlier and head through Fishponds!! The "fastest route" was enabled. I ignored it and it self corrected only when we'd managed to find ourselves a few hundred metres from where we needed to be. It seems to do this quite regularly in this area especially. No road alterations have been done in this area since my maps were installed (I think ours are 2015 updates on the 2016 car).
  8. This was the view outside this morning for us. Minor roads buried, drifts on main roads on high ground and all untreated side roads under 5 or 6 inches of snow. Used a motorbike hot air dryer to blast the snow off the car (could have been made for the job!), was one of the first vehicles on our untreated side road to make it onto the mains road this morning. Drove the Mrs in to town to do the weekly shop, came back and will be firing up the workshop heater ready for a late work start this morning! Even on the Avon ZX7 summer tyres, the rx450 had no problems. Left it in snow mode and it pulled us out of a few iffy hard packed snow areas, slowly but surely. Over virgin snow it's a doddle. Just had to be careful as some of the kerbs weren't visible!
  9. Just come across this stuff which claims to be safe to use with tpms systems: https://www.ebay.co.uk/itm/2-x-Emergency-Spare-Wheel-Alt-for-Honda-Civic-Flat-Repair-Space-Saver/172713549388?fits=Car+Make%3AHonda|Model%3ACivic|Cars+Year%3A2016&hash=item2836879e4c:g:IR8AAOSw-K9ZNHBS:rk:1:pf:1&frcectupt=true Not sure if I'd take that risk personally.
  10. The TPMS issues is a very good point as I hadn't considered that and have been glibly carting around tyre weld, should the worst happen. I'll ditch that now and just use a plugging kit instead if for any reason I can't get the wheel off (it's what most of the AA vans use anyway in emergencies) and keep the compressor in the back of the car. I keep such a kit on the bike and they are relatively simple to use, most being based upon finding the puncture (obviously), removing the offending item (if still embedded), reaming the hole out using a tool provided, the smearing glue on a sealing band which is then pushed into the reamed hole. It's left 5 or 10 minutes then cut off flush. It's more reliable than tyre weld anyway and you can drive up to 50mph with some to a garage to get the puncture properly repaired.
  11. Yes, I usually plan my route on maps, and only when I'm close to where I need to be do I activate the satnav system (or my wife punches in the code so I can keep my eyes on the road).
  12. I remember keeping track and comparing my E46 6 pot beemer and my GS300 winter and summer figures and they were very similar percentage-wise to the drop in efficiency of our RX....about 10% for each so I haven't seen any marked difference between the hybrid and non-hybrid. Mind you, a lot depends on the topography. As I live in an area where to get anywhere, hills and twisty country roads are involved, then there's bound to be less difference anyway because the engine is used most of the time, hot or cold. Hybrid savings only really apply when creeping along in town or on low average speed flat runs which we very rarely encounter day to day here. Also, heated seats aren't much used by us, perhaps for a few minutes whilst the engine warms up and cabin temperature climbs. After that we usually switch them down or off.
  13. Yes, it's one of my bugbears when almost all the major players now include free updates for life, Lexus still charge more than the cost of buying a decent Tom-Tom or Garmin Nuvi (which incidentally appears to work more reliably than the Lexus satnav in the 2016 RX!). When the time comes, I'll buy a Tom-Tom for £120 or update my Garmin and use that and pocket the change from what the sDealer would have charged. To be fair to the dealerships, they get charged what they get charged and add the minimum labour rate in atop that, but even so, even £150 is steep let alone £250. I'm unsure of how the satnav system is updated but doubt that a technician would have to sit there for an hour or so whilst the maps update.
  14. I think that there's some crossed wires here and indeed some rather unfair comparisons being made. Lets start with electricity production by type for 2016 (Source: Wikipedia): In 2016, total electricity production stood at 357 TWh (down from a peak of 385 TWh in 2005), generated from the following sources:[50][51] Gas: 40.2% (0.05% in 1990) Nuclear: 20.1% (19% in 1990) Wind: 10.6% (0% in 1990), of which: Onshore Wind: 5.7% Offshore Wind: 4.9% Coal: 8.6% (67% in 1990) Bio-Energy: 8.4% (0% in 1990) Solar: 2.8% (0% in 1990) Hydroelectric: 1.5% (2.6% in 1990) Oil and other: 7.8% (12% in 1990 The figures above clearly show that the major single contributor to production was Gas at 40.2%, some 20% above the next largest producer of Nuclear energy. It is not clear whether these figures included for the spinning reserve needed to back up high diurnal demands and periods of low or non production by renewable sources during high demand periods. The National Grid have themselves informed Government that unless there is tangible movement on letting contracts (ie planned increased production strategy with contracts needing to be fleshed out now, not in a decade's time as it'll likely take that long for the procurement and delivery processes to hit the ground) then we will require a rise in capacity of between 3.5 and 8 GW to meet the increased demands imposed by the forecast switch to EVs on our streets and that atop current peak demand of 60GW. They cited an example of what that means in reality and it compares with a little over 3GW capacity added by the current Hinkley Nuclear power station project. They also cite forecasts by 2050 of a need for an additional 18GW capacity based on all vehicles switching across to electric and those figures do NOT include any increased domestic or industrial demands. Forgive me, but where amongst that lot does it suggest that we have adequate capacity when the National Grid themselves say that we haven't? It will take a huge net increase in renewables or several more Nuclear power stations coming on line and thought must also be paid to those stations yet to be decommissioned or upgraded. Your comparisons on energy use for the electric cars neglect production costs (environmentally) and recycling and disposal costs. Just about every part of a current combustion engined car can be currently recycled in some way but I understand that the same is not true of the Li-Ion batteries. What I mean is that at least here in the UK there are no recycling facilities for Li batteries, they have to be shipped abroad. Add to that some of the inflated and down right dishonest claims on reliability and range by companies like Tesla, and their cars are far from an attractive proposition let alone affordable (entry level models being in the mid £60K region). Even cheaper all electric EV cars cannot compete on range or purchase price with equivalent petrol cars. Whilst that doesn't affect the choices made by some, it certainly does by most people. I was hoping to be persuaded otherwise but nothing has changed from my perspective, and the figures quoted above are all from official sources, so hopefully that has answered your queries? You have really to point out the comparative efficiencies of EVs on a whole life basis, for a comparative mileage, the life expectancy itself and the related carbon footprint. Those are the only true measures and not what things cost the consumers or what comparative motive efficiencies are at a certain point We need to walk into these decisions with open eyes about what we're doing, in terms of to the planet as much as to our wallets! For the moment, for many of us at least, the 6-pot petrol engine rules! Couldn't care less about the boasting of Tesla and others about performance. It's immaterial on our roads except (at least imho) for safe overtakes and load lugging. Once you're up to a certain performance point (lets say any car that is capable of a 30-70 within 4 or 5 seconds has adequate performance, any less than 4 seconds and its pretty quick) then comparisons are for racetracks and for those who like to wave their little things about in the faces of others. If what you want is a fast car because it's fun, go for it. I've done just that in the past. Now I care less about top trumps but want safe reserves of power. Debate is healthy though as it helps shape our understanding and also where others might be coming from, and respect to that.
  15. It's perfectly normal for mpg to drop in colder conditions and it has nothing to do with the hybrid system. Colder air is denser air, so more of it gets taken in. As your cars all have mass flow and density sensors, they pick up on this and to maintain a balanced stoichiometric mixture (A/F ratio to you luddites), the ECU ensures that the mapping is richened up to balance the total air mass. This has two main effects: 1) greater power output (bigger bang = more power and torque); 2) worse mpg (you use more fuel per engine revolution). There is a third contributing factor...some or many of us will leave our cars idling to warm them up and demist and idling on cold running fuelling will gobble petrol. I'm currently achieving 27mpg combined (short trips plus hills) which is 10% down on summer figures. 10% drop in mpg isn't that untypical.
