“Lost power in my 2012 v6 Mustang. Wrench light came on indicating limp home mode. Was able to pull off to the side of road. Turned engine off and the it was fine for about two miles then cut off again. Restarted again and was able to make it home but the engine light is on. Going to try and get it to the shop tomorrow, but this is a severe safety problem in my mind. Was lucky I didn't get rear ended”

Unattended acceleration happened twice in the same day and the second time I could not get it to break free and stop until the last second but it was too late it hit the semi truck trailer in front of me. This was inspite of me having both feet pushing strongly on the brake pedal. We had started off slowly from a red light and then the car downshifted and took off. Southwest Ford in weatherford, tx had called the Ford engineer to come look at it. It took a month for him to come. …”
