RX400H

  • 52,549 miles
On September 18,2019 @~12pm while parking my 2007 Lexus Rx 350 driving at very low speed <5 mph the vehicle suddenly accelerated hopped a curb and I went into the road. Thankfully I didn't crash or hit anyone. Mileage at time was 52549. I read on here other people had similar issues. I didn't see any recalls for this problem on my vehicle. My floor mats are no where need the gas pedal. The mats are locked in place by the pin. They don't move. I plan to take the car to Lexus dealership. They must be aware of this issue.

I was in a parking lot of my business entering a parking space. As I was trying to stop I took my foot off the gas and I applied the brake, but the car all of a sudden leapt forward and hit a wooden post directly in front of me, up on a walkway. In order to stop I put the shift into reverse while continuing to apply the brakes.

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.

RX400H

  • 4,000 miles
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.
