Hi,
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?
Cheers
Phil
