“Preparing to stop while entering access gate slowing to around 10 - 15 MPH, after applying brake car accelerated forcing me to reapply brake again and shifting to park. This is the first time that this high level acceleration has happened although before I have noticed occasionally a low level acceleration when preparing to stop.”
NHTSA complaint #10692948, filed 2015-03, 201,000 miles“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. I was able to drive it home. In my 45 years of driving many different vehicles, this has been the most scariest feeling.”
