I have noticed this issue a couple of times over the 7 years I have had the car (since it was new), most recently yesterday: when I am traveling at medium speeds, say 30-45 mph, and I hit a bump it feels like I get a little "push in the butt". Sort of like a forward skid. So then I apply the brakes a bit. Don't know how else to describe this. My husband says that he can't feel it when he is a passenger.

Lexus Rx400h not on any recall list by Toyota. Have had multiple incidents of braking/acceleration problems. Toyota won't do anything except say bring it in for a test drive.

I know what the car does, I've driven it for nearly 3 yrs with approx. 12 incidents of the problem. Can you help?.

This relates to possible problems with Lexus cars. I don't know if this information is useful or not. I took possession September 2008 of a brand new 2007 Lexus 400h. I drove the SUV approximately 5 miles when all of the dashboard warning lights came on and the engine stopped. I coasted to the bern. I was able to restart the engine but the hybrid system failure alert was on. The dealer had the car tested by their hybrid specialist. The diagnostic computer apparently registered nothing wrong. The hybrid technician took the car for a test drive with the diagnostic computer on board. The same problem occurred. The diagnostic computer did not register any malfunction. The general manager of metro Lexus in cleveland spoke with Lexus USA. The took the SUV back and exchanged it for a new 2008 RX 400h. There were no problems with that car.

I just wanted to let you know that my wife and I have experienced the engine accelerating on the 2007 Lexus 400h while coasting to stop signs. This occurrence started about 3-4 months after we got the car and does not occur all of the time. The gas pedal seems to override the engine acceleration problem, however, the issue seems to be similar to what others have seen in other cars. This issue has been reported to the dealership in the past before the recalls without any satisfaction. This model is not on the recall list, but I wanted to raise the concern as it seems to be a problem similar to what is happening in other vehicles and may help to indicate that the true issue may not be the floor mats or the gas pedal design. My wife is concerned since the engine is accelerating without the gas pedal depressed. Since the brake is overriding the acceleration, it would indicate to me that the issue is not a sticking gas pedal.

Lexus Rx400h, accelerated while brakes were applied causing an accident. Also the vehicle's brakes were such that the there was a slight delay that had to compensated for or you would pass intersections or turns. The vehicle still accelerates at times when brakes are applied.

When braking and car encounters rough road or a pothole, car lurches forward and loses complete braking power. Have to depress brakes all the way to bring to a stop. Occurs consistently with above stated road conditions. Dealer service refused to acknowledge problem and claimed to have never had similar complaints.

The vehicle surges at a steady speed. I am most aware of the surging at 35-45 miles per hour. This did not happen until the vehicle had approximately 8,000 miles on it. I have been told there is no repair available and the Lexus is aware of this problem.
