I had this happen to me three times within a period of two years and 17k miles and I was able to duplicate it intentionally after a dozen tries. The third and last time it happened it almost killed my wife. I had the car in reverse and the car completely stopped with my foot pressed hard on the brakes. …”
NHTSA complaint #10146822, filed 2006-01, 17,000 miles“I have a Hyundai XG350 2003. I had three incidents with it: two summers ago, I put the car in reverse and backed up few feet and stopped to look if it was clear to continue. My foot was on the brake, the car was stopped, then suddenly it lurched back, stopped then lurched back again and again, finally it stopped. I reported it to the service people and they said no way that would happen. Last summer, it did it again, but this time it lurched back only once. Last september, backing out of the garage, I stopped, pressed hard on the brakes to let my wife in. …”
