3 Vehicle Speed Control problem

Failure Date: 09/01/2013

I stopped at a traffic light and all of a sudden my car started to accelerate, I pressed the brake real hard but the car lunged forward ahead. Quickly, I put it into neutral. It continued to accelerate to over 7500 and then went back down. Luckily no one was in front of me and the person at the intersection saw what was happening and he swerved away.

For the sixth time, vehicle accelerates or surges. This time at 2 mph, but it has also happened at 45 mph. It only lasts a second or two. Has happened 6 times in 15 months of ownership.

There are a total of only two for the same years of the Lexus es300, mercedes 320 and BMW 5-series combined. Please do something before someone is killed!.
