When driving, the car engine will randomly accelerate or race. The car does not physically go faster, but the engine revs at a high speed which is very scary. It will continue to accelerate while your foot is off the gas until you either press back down the gas pedal or come to a full stop. The car engine revs extremely loud making the driver feel like the car is going to keep going. I have had the car for 15 months and it continues to get WORSE. I have taken the car 3 times to the Lexus in Freehold NJ when I first bought it to fix this issue. They were able to replicate it in my car but said the tests came back normal and told me this was a "normal reaction" due to the car being a hybrid. The diagnosis was that it was the battery discharging. I wrote to Lexus and the regional service manager, but they have all dismissed me. I filed a complaint with Lexus, but they also dismissed it. I just went on the Lexus Forum site to find many people are now complaining about this issue. What is very interesting is that Lexus has now put out an "Unintended Acceleration (UA) form which asks questions about this issue. LEXUS KNOWS about this major issue but has yet to do anything about it. The other day I approached a few kids playing in the road and started to slow down only to have the car loudly accelerate/rev as I was approaching the children. Very unnerving...something definitely is wrong and needs to be addressed. I was hoping you could help since the manufacturer refused to.
