Hi RXboil The fault is the transmission oil pump - at first I thought it was the inverter coolant pump. The list price for the pump is £850 - you can get the genuine part part for £350ish. However, I was stuffed I had to get on the road immediately and my local independant Toyota/Lexus specialist in MK had one on the shelf. It was 2 hours labour to fit. The good news is the fault is fixed and the car runs better than ever. In the past if I put it in gear and accelerated quickly there was a little bump. Now it is as smooth as silk. The Lexus dealer did not deal with my request to investigate. £1K to sort it out. I expect it will be more at a Lexus dealer. The last time I talked to them they wanted £450 the change the front break pads and £660 to replace the rear disks and pads. I use independents these days. Good luck Bren

Thanks - I'll take a look.

Hi Adrian I spoke too soon! 15 miles in to my ride to the golf club the fault came back. The pump is running now because the coolant was hot. I need to have a look at the latest fault. Techstream tomorrow. Bren

You should not try and jump start another hybrid either.

New inverter cooling pump fitted and everything is fixed now. £300 for the pump, £260 to have it fitted.

I sourced a new assembly from Rock Auto for £400 delivered took - 3 days from the US.

Then you have a fault.

If the battery discharges on the drive way over night you have a fault or a bad battery. I put a new bat in just after Christmas and regularly leave my car sitting for two weeks with no probs. Over Christmas I left it for a month and the bat went flat - I charged it and it would only go to 75%. It still started the car OK - note it was the original 11 year old battery. Bren

I have a 2012 RX450h and the wiper rack broke - I had to replace it. I think it was damage a few years ago when it was iced up. It is a pain when the wipers stop at 70 in the outside lane of a motor way when it is lashing down.

Hi The tank capacity is the first fill capacity - there is part of the tank you cannot use. Sound daft but...

Hi I regularly drive to the South coast and back (an overnight stay included) and achieve a34/35 mpg. I run on E5 fuel with E10 is drops to 30. I find a constant speed is the secret to lower consumption so I use the cruise control at 70 where I can. Round town 30mpg is difficult with the stopping and starting. I keep my tyres at 34psi - I think the ride is a bit hard but it uses less fuel. I have done 121K miles.

Hi After 35 miles, on Monday during the hot weather, the check hybrid warning came on and the hybrid systems was not doing much i.e. the regen braking was not working. The cruise control did not work. I stopped to make sure I could start the car and it seemed OK. The next morning the check hybrid light was on but everything worked. Another hot day and 50 miles on the way home the problem happened again. I see a P2602 code on my reader but it cannot be easily reset. I reset it by disconnecting the battery tomorrow. Anybody have experience of this? The fault is Coolant pump A control circuit low. That could mean a faulty pump, ecu, connection.... I did see it cost somebody on here £1K at a dealer. Any pointers for more advanced diagnostics would be appreciated. Cheers Bren

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
