NHTSA Complaint #11560593 — 2008 FORD MUSTANG

I have a 2008 Ford Mustang with a V-6 engine. Recently I had to jump start it twice in a week's time to get it started and decided to take it to my dealer to have the battery checked. On the way there, I had to stop for a line of line of traffic at a red light. The instant I applied the brakes the engine started racing. I stood on the brakes as hard as I could, but could not bring the car to a complete stop. I got it slowed down to about three MPH, steered it into a parking lot that was next to me, and shoved it into park. I was afraid to drive it, so I called AAA and had it towed to my dealer. I told them how the engine started to race when I applied the brakes, and that I couldn't bring the car to a complete stop. They wrote it up that the engine started running rough when I applied the brakes. That is not what I told them. They made no written reference to the unintended acceleration. This struck me as odd. Their analysis of the vehicle showed that the master cylinder and brake power booster had failed. They told me that sometimes when these components fail they can cause the engine to rev. My engine more than revved, it sounded like it was racing at full throttle. The incident shook me up quite a bit. It also seemed odd to me that two major brake components would fail at the same time. I had gotten new front and read brake pads earlier in the years and no other brake issues were discovered. Though the car has been repaired and seems to be OK, I'm somewhat skittish about driving it. I'm aware that there was a class action law suit filed against Ford in 2013 for 2002-2010 Ford vehicles claiming unintended acceleration. Though the suit was dismissed, I'm worried that the problem still exists. I know for a fact that my foot was fully on the brake pedal, and that the floor mat played no role in this issue. I had no similar issues with the car in the fifteen years prior.
