“Vehicle was purchased used in june, 2011. While braking for a stop light, vehicle suddenly accelerated. Had to forcefully pump brakes to stop vehicle from hitting vehicle in front. Car returned to normal operation as soon as I got it stopped. Have had similar incidents a couple of times before, although not as bad as this one, however, at that time I thought maybe I had accidentally pressed the accelerator while braking. I know that was not the case this time.”
NHTSA complaint #10535491, filed 2013-08, 56,150 miles“Had a flat tire and had to install the spare tire that came with vehicle. As soon as I got back on the road , the stability control light, the ABS light and the I-p brake light came on. The car would get only 35 MPH. For about 7 to 8 miles, then picked up speed so I could run 50 MPH. Until I had the tire replaced. After I had the tire replaced I took the car to a mechanic to have the system reset so the lights would return to normal. The unit that controls this had to be replaced because the difference in tire size had destroyed the control unit. …”
NHTSA complaint #10509754, filed 2013-04, 56,122 miles“On october 27, 2010, my wife was driving with me in the car and she started to brake for a red light. She was going about 30 miles per hour. As soon as she applied the brake, the engine accelerated and she had to use a large amount of braking pressure to stop the car. As soon as the car stopped, she took her foot off the brake and the engine returned to idle. Yesterday, I was driving the car at approximately 55 mile per hour and started to move into the passing lane when the traffic light ahead turned red. I applied the brake and the same thing happened. …”
