19mpg. That is not good. Have you tried the ISC reset procedure? https://us.lexusownersclub.com/forums/topic/58930-isc-learning-procedure-without-lexus-diagnostic-tester/

What about an RX300. Not much difference compared to the RX350, especially at the low mileage you cover. I would avoid the SE-L model with the air suspension though.

Thanks everyone. Happy RX owners as expected. Watching the latest forum thread now!

Thanks jumpingjehovahs. I too am thinking the price is a bit high, but are hybrid prices quite strong at the moment?

Hello all. Having previously owned an RX300 and 400h, I have been lost in the outback for a few years but considering a return to the fold. I have my eye on a 2010 RX450h SE-L Premier at a Lexus dealer and priced just below £17k. It has covered just under 90k miles and of course has all the bells and whistles. I am a little concerned about the reliability of the air suspension system. Do I need to be? Any comments on what to look out for on such a car, and whether the price is fair would be much appreciated. Thanks.

I did wonder about the F Sport suspension setup but didn't question his statement as the F Sport would not interest me anyway. A quick check of the brochure shows the F Sport with performance dampers and a unique suspension, so of course you are quite correct.

Just got home from a test drive of the NX Premier. The salesman informed me that the F Sport has the same suspension setup as the rest of the range, although adaptive suspension is an option. I too found the ride uncharacteristically Lexus like with far too many minor road imperfections being felt in the cabin. Power train a little slow after my Volvo diesel but nicely refined of course. The dash seemed a bit of a mess with buttons everywhere although many will probably not be used too often. Final dislike was the boot cover. A sliding cover as in the RX gives much better access. Overall I thought it was a superbly designed car with a refined drive train, but the final package could have been much better. Shame as I would love to get back into a Lexus but this may not be the one for me.

Worth a look. http://www.chipex.co.uk/?gclid=CMfRmeDLn70CFZShtAoddWUA7Q a look.

Try the ISC reset procedure at the link, it has worked for me and others in the past. http://www.lexusownersclub.co.uk/forum/topic/79992-rx400h-mpg-new-member/?hl=%2Bhybrid+%2Breset+%2Bprocedure#entry797863

The wire is actually the glovebox retaining strap which loops over your lonely screw. Yours has come adrift. Hope this helps.

The Caravan Club recommends a noseweight of 7% of MDW (Max design weight) of caravan. Some say 4% - 7% is fine. 80kg limit for the car is approx 4.5% of your proposed 1800kg MDW caravan. You takes your chance. Probably ok if its is a twin axle which seems likely at that weight. Also need to be aware that a general recommendation is that the MDW of the caravan should not exceed 85% of the Kerbweight of the car. RX400h Kerbweight is 2040Kg 85% figure therefore is 1734Kg An experienced caravanner would probably be fine with the outfit you are looking at, but I would not recommend it to a novice.

I have towed with the RX300 and now RX400h. To be honest the difference in towing capability and fuel consumption is not significant. The RX 300 in my opinion gives a smoother and quieter ride but does loose out to the 400h on performance. An RX300 can be found for much less than a 400h and often with sensible mileage, and of course no Hybrid worries .http://www.autotrader.co.uk/classified/advert/201306117234585/sort/default/usedcars/maximum-mileage/up_to_80000_miles/price-from/6000/price-to/7000/fuel-type/petrol/model/rx/make/lexus/onesearchad/used/onesearchad/nearlynew/onesearchad/new/radius/100/postcode/po62jy/page/1?logcode=p If you are new to the RX scene and need to get in cheaply, I personally would go for something similar to that at this link.

Not sure what you are trying to find out, but if you ask a Lexus dealer to fit a detachable towbar to your car, it will most likely be a Westfalia branded model. Check their website for details.

The fuse box for this one is located below the glove box. It is quite difficult to access, lie on your back, remove trim below the glove box to reveal the fuse box which is about 6"x3". Sorry but I cannot remember which fuse feeds the 12v sockets. Have fun!

I tow a 1400kg caravan with my 400h and it is both very secure and a powerful towcar. Fuel consumption towing is around 20 - 22mpg. It will pull the van at low speed on batteries alone which gets plenty of surprised looks from other caravanners as you glide silently around the site. Take care not to catch some unaware though. A word of warning though. If you get caught out on a muddy pitch with a bit of a slope, you may struggle to pull your van out as the hybrid system will simply not allow the drivetrain to spin the wheels fast enough to drag the outfit out. Not something you should be doing anyway. In short, the 400h is a superb luxury vehicle which makes an excellent all round towcar, If you are, or have been a Lexus man, why settle for anything less.

My 400h was serviced by my local Lexus dealer 3 weeks ago. The invoice shows they used Castrol Magnatec 5w-30 C2 fully synthetic oil. Good enough for me.

Quite correct. I contacted my local dealer who has quoted £540 for the Lexuscare Listed Parts Warranty which has a claim limit of £2000. And yes, this can be paid for with 10 interest free payments by Direct Debit. Seems pretty good value, though some may be wary of the claim limit which may not cover the cost of any serious repairs to the Hybrid components however unlikely a failure may be.

I am not sure what the 5plus warranty you refer to actually is. The only one I have been offered by my local Lexus dealer for my 06 400h is the one shown at the link. Does anyone know of a cheaper genuine Lexus warranty?

Lexus extended warranty can be found here: http://www.lexus.co.uk/owners/warranties-repair/#/Search

Underneath the glove box. Remove the trim then the fusebox can be seen as you lie on your back looking up below and behind the glovebox. Its difficult to spot, about 6" x 3". Have fun!

This is it. The instructions are as follows - This applies to the 2006 Highlander Hybrid also. Note that you can probably perform the procedure yourself. The scan tool mentioned in the procedure checks the coolant temperature to make sure it is at full operating temperature and checks the engine loading to make sure the load is sufficient to charge the battery and finally checks the status of the ISC learning parameter. It is not necessary to monitor these parameters if you do the procedure carefully. 1) Make sure the vehicle is fully warmed up. Do the procedure immediately following a long drive that runs the engine (highway speeds are best - not long gliding stealth runs at low speeds with the engine off). This will insure the coolant temp is at FULL operating temperature - it is not necessary to actually measure the coolant temperature if you warm up the engine sufficiently and don't let the engine shut down too long and cool off before doing the procedure. 2) With the vehicle stopped and in drive, press firmly on the brake to keep the vehicle from moving and then step on the accelerator while watching the power meter (to the left of the speedometer). Press down on the accelerator to keep the needle between 1/2 and 3/4 up the scale. You will find that the engine management system will automatically limit the engine load no matter how far you press down on the pedal so the amount you press is not critical as long as it is either 1/2 scale or to the engine's self-limiting load value. Keep the engine loaded for a full 30 seconds but not longer than 40 seconds (this procedure brings the hybrid battery up to a maximum state of charge - if you watch the battery symbol, you willl see it tick up to a "full" display). 3) Shut off the engine and place it in park 4) Wait 5 seconds. 5) Turn the ignition key back on to display "ready" 6) make sure the A/C and heater system controls are set to off 6) Lightly step on the accelerator pedal until the engine starts -then immediately take your foot off the accelerator and let the engine run until it stops by itself. This completes the procedure. _______________________________________ I've done this procedure successfully a few times now (ran my battery dead once, and disconnected another time when trying to reset the NAV system) The only thing I noticed (and it didn't seem to matter) was that I could not get the power meter anywhere near 1/2 to 3/4. No matter how far I depressed the accelerator, the engine management system would not let the power climb even 1/4 way. Everthing else worked as stated though.

Hi I have only once had a full house on the battery charge indicator and that followed a 2 miles plus downhill run. Fuel consumption is very dependant on ambient temp so you should see an improvement in warmer weather. May be worth doing a search for the Isc Learning Procedure. I did it once following an aux battery replacement and it seemed to work. It may not work exactly as the procedure in the posting though.
