I'll give it a go - I love magic potions. Cheers Bren

That's impressive fuel economy Vlad. I have a 2012 and 30 is doing OK.

Just saw this after a quick search - coil over conversion kit for RX450h https://www.fittedvisions.com/products/fv-suspension-coilovers-08-15-lexus-rx450h Look like a £1K ish - may be some tax. I did this years ago on a LS430 when the air suspension bags started leaking and the ride height sensors wore out. Rockauto may have the parts a lot cheaper that Lexus UK will sell them if you want to fix your existing suspension. Good luck Bren

Hi Dave I drove over 350 miles in the last two days. The first half of the trip was using E10. I have been struggling to get much more than 25 mpg lately but I have not been driving much. With sensible driving I used to achieve 30 ish. Last night I filled up with E5 and within 70 miles I was getting 28mpg with mixed driving: motorway, town, traffic jams etc. I think the car runs smoother on E5. I don't think I am suffering from confirmation or inclination bias - I test things for a living. I am with you on the driving style - fuel economy and penalty points sorted mine out.

I can get about 30mpg in my 2012 model - I get a few mpg more from premium and I think the car runs better. I am about to start driving more than 500 miles per week so will do some analysis. The emergency filler door release is under the boot floor - this may help. The emergency tailgate release is at the bottom of the back door - you have to crawl in. See my post about my recent failure - there are many others. I have attached a useful document for people who are new to the RX450h - it is the electrical system dismatling guide. However, it has some really useful info in it. Regards Bren RX450_GYL2.pdf

Fix completed yesterday. New battery was needed - the old one was the original from 2011. It was down to 75% but still working. Lexus parts (Swindon dealership) off a great price - I have a trade account there. The tailgate would not open automatically after the new bat so I bought the ECU and motor. £1200 list price plus fitting was a bit steep. I bought a new one from Rockauto for £275 - delivered for £400. I odereded it at 10:00 New York tine last Saturday; they packed it at 11:00 and shipped it. I received it at 12:00 Tuesday. That is service. I had it fitted by my local garage - £55.00. It's not hard to do yourself - here is a good Youtube video on how to from Viktor G: https://www.youtube.com/watch?v=6pZ_pU0Bqxg

Hi my 2012 RX450h tailgate will not open. Any ideas how to open it? The car starts and runs OK. I think I hear the lock kclicking - I checked the switch in the glovebox and it is in. The AUX battery went flat over Christmas when the car sat for 4 weeks or so. My wife does not like driving it and I was laid up after surgery. I have read a few posts but cannot find how to open the tailgate manually. I suspect the battery may be duff now. If I want to swap the bat I will have to get it open so there must be a way. I will charge the batter from under the bonnet - it seems that some people had success with this method. Any suggestions (to open the tailgate) will be much appreciated - I know flattening a lead acid battery is a bad idea. I am an electrical engineer!! I don't want to fetch a crow bar to the back door. Regards Bren I found how to open the backdoor on Youtube. A pain for a fat old boy like me!!

Thanks Herbie I suspect the garage only disconnected the aux battery but will check. The alarm has stayed off.

When I started the car to check for any codes the warning had cleared. There was a P0A0D code that I cleared. This is a high voltage interlock problem - seems to be spurious. The battery was disconnected when some work was done yesterday - I assume it was related to that. I looked around and saw that this code is often associated with a failure of the hybrid system.

Hi All I had an independent local garage carry out some work - reline the front brakes, replace rear n/s trailing arm and fit a new cruise control stalk. After which the check hybrid system warning came up. The car is fine and the hybrid system is working. Anyone seen this before? I will poke about tomorrow and will be happy if anybody has an advice. The cruise control switch was only £20 and was probably the biggest job - air bag disconnected etc. This mean the battery was disconnected which meant the darn car started talking to me and beeped every time I touched the mouse. Any ideas would be great. It is going to a Lexus dealer for a service, MoT and hybrid check very soon so they will probably charge me £200 to look at it. There have been no probs with the car - it has been rock solid. It has been to a local garage because Lexus wanted £450 to replace the front pads and £550 for the trailing arm. The local guys charge £50 per hour and are booked out 3 weeks ahead and are great. We put Lexus parts on. Regards Bren

That's exactly what I was thinking Phil - my bank gives me free AA - well provides it because nothing is free from a bank. I will look at Motoreasy's satisfaction rating before I decide on the Lexus backed offering in a couple of month's

I will see if I can obtain this warranty with Lexus Cov when they MoT and service my car in November. My Motoreasy warranty only costs £350 and covers what I need - however, a Lexus product would be better. I received good service in 2021 when the old one expired. A good discussion as usual guys. We need to remember the dealers are not Lexus they are franchises and are only as good as their staff. Regards Bren

Lexus stopped selling extended warranty - they were giving it away but only for cars with less that 100K miles at 10 years old. I am intrigued that Bill could get a Lexus warranty. Just before my last extended warranty ran out I had £2000+ of work done - the front bushes and some air conditioning work. That warranty was sold by Lexus but provided by a third party. My local dealer is Coventry and were adamant in 2021 that there was no extended warranty available from Lexus. Lexus will extend the traction battery warranty if you keep the health checks up to date. I have mine serviced at a dealer so the batt health check is done then. I took a warranty from Motoreasy - it is £350 a year and covers all the important big stuff. I have it on auto-renew in case I forget.

If they did not test the 600 then they will say the newer fuels are not supported.
