What owners wrote

We have had issues with this car since it was bought new. All issues have been looked at by the dealer during the factory warranty and still remain unresolved. I have written a letter to ford headquarters but they sent a complete rejection letter. I was told today by a ford customer service representative to file a complaint here. I can supply documents and the original letter to ford if needed.

Reported at 100 miles, March 2003 Crash

2003 ford mustang cobra has a stalling problem, this happens when decelerating, or shifting into neutral when stopping. This presents a serious problem, such as rear-ending someone, since you loose power braking and steering. There is a supposed fix for it, (a computer reflash) which I have had twice, but it just plain doesn't work.
