Thanks for the helpful replies

I have recently replaced my 12v Battery ( see other thread )

While googling my problem I read somewhere that the RX400h shoudn't be used as a donor for jump start.

Is this correct and what is the general advce regarding use of jump start both as donor and receiver of jump start.

I don't nee to do either immediately but it would be good to know for future reference.

Thanks for all the feedback.

I changed the 12v Battery and everything has been OK for the last couple of days.

The old Battery had a 2017 label on it.

thanks for the helpful replies , much appreciated

I'm not recommending turning ignition off , simply reporting what i did.

Ive had my 2008 RX400H for almost 3 years and it has been faultless , taken from 88,000 to 110,000 miles 

Last Friday morning with heavy overnight snow I started the car and put on heaters and left the car for 15 mins to warm through. When I returned the engine was off but heaters on. I turnd the ignition off but when I tried to start the car a short while later it would not go. I tried it again 30 minutes later and it was fine. Ive used the car for last few days including 2 journeys of over 100 miles without problem.

Today, I was driving along when the message 'CHECK HYBRID SYSTEM' appeared on dash. I continued to my destination ok, but when I tried to start the car I got the same message and it wouldn't drive.

A quick google and I disconnected 12v Battery for 10 minutes then reconnected and the car started / drove. However the 2 messages CHECK HYBRID SYSTEM - CHECK VSC SYSTEM appeared on dash , I drove home, parked on my drive and the car again will not start.

Does this sound like a 12V Battery problem ? Sounds unlikely that hybrid and VSC would fail on same day.

The 12V Battery looks old and was on the car when I bought it March 2020 and could be much older.

If I did replace the 12V Battery would the system also need reset ?

Any suggestions welcome.

Thanks

Hi,

Does this sound like the pump may be gone or is there another cause.

My front windscreen washer is not working there is no liquid coing out, however the rear washer works fine.

Do rthey have seperate pumps ?

Thanks for any advice

Hello,

My first post here, I've just purchased my first Lexus, a 2008 RX400h.

Early impressions are very positive and hoping to keep the car for a good while.

The car has covered 88,000 and has a comprehensive service history with 13 service stamps from dealership and independent specialist backed up by invoices.

I am based in the North East. I haven't located a located an independent specialist. Can anyone point me in the direction of any garages they have used in this part of the world, i.e. Sunderland/Durham/Newcastle area.

Thanks
