RX400h 2008 65k miles
Have an issue that the Lexus guys say they haven't seen before.
When accelerating hard I get what feels like a misfire. If I continue to push hard the level of charge in the traction Battery starts to drop and shows empty withing 3-4 mins. No service or error lights show.
On a longer journey last month I did get a service light when I felt the misfire. Lexus did the diagnostics and reset and said it was cylinder 2 slight misfire. Strangely on the journey home the misfire appeared to have gone and the car accelerated cleanly to high speed. Great I thought, its sorted. Sadly not and after 2 days the problem is back. Car drives perfectly in all conditions other than hard acceleration.
Lexus have checked all major components and cant find an issue, so have said to continue to drive and see if an error can be forced.
Has anyone had a similar issue or any ideas?
This is my very first post!!
Does anyone know what is under the carpet in the rear centre passenger well in my RX400H? I have 2 wet spots that have appeared in the last couple of weeks just under the hybrid Battery vent. It's just on the bump in the floor. They are about an inch wide with an inch gap. It is definitely coming from below as there are no leaks from the sunroof or lining. I have scoured the 'interweb' and nothing on this topic. I am hoping nothing serious but certainly a strange one!! I am hoping a car breaker or anyone out there may shed some light?
