I was driving a 2010 Lexus rx450H on a highway at @60 mph when it accelerated on its own to @80 mph within a few seconds. It responded to the brake and I exited the highway. I had the vehicle previously checked by the dealer, rallye Lexus in glen cove NY, and they said they were no problems. The dealer and factory rep. Checked the vehicle after the incident and they again said there were no problems with the car. However, the event did occur and now I will not drive the vehicle. Fortunately there was no accident as a result of the malfunction.

My car suddenly accelerated as I was parking and hit a concrete wall. I was almost in the space and going 1mph aprox. 3 or 4 feet from the wall. They said I stepped on the wrong pedal to cause it. I did not, but lost my confidence and trust in my driving. The model car is a 2010 Lexus model RX350. Not on the list of recalls. The damage was in excess of $14,000. My insurance paid all but the deductible. I still do not believe that I did what they say and do not trust Lexus to tell me the truth of the matter at this time. The car went straight to the dealership for repairs.

It's a Lexus rx 350 2010, the truck seems to accelerate or lurches forward with brief spurts of acceleration, the lapse in braking is probably less the a second. It happen while I brake to a full stop. I take the truck to two Lexus deal for concern, but they said, the vehicle is operating as designed, when they compared to same model vehicle. They also said that lurches is, the vehicle is preparing to shift into next gear so it's ready to shift to a different gear.please review this incident so that I could get this off my mind.

We had a 2010 Lexus 350rx. In Aug 2009, I was driving home and the car accelerated up to about 60mph. My husband was in the car with me. We were trying everything to stop the car. We finally got it stopped. It did it a second time with my husband driving the next day. We know without a doubt that it was not the floormat. Which that is what Lexus blamed it on. I would not drive that car again.
