“While slowing down, downshifting or switching gears, the car engine will just fail and shut off/stall without any warning. The car will not buck or shake, it will just turn off, causing the power steering to stop operating. I have had two close incidents where I was turning into a parking lot and almost hit a car because the power steering shut off when the engine died without warning. I am afraid this problem will cause a bad accident, especially when I have two young children riding in the vehicle most of the time. …”

“I purchased a new 2003 Ford Mustang cobra on christmas eve 2002. Around 2000 miles, I began to notice that the car was having problems with the drivability. I thought that it may be a little quirk that would work itself out during the break-in period. Needless to say, it hasn't. The first problem began with the engine running roughly. I took the vehicle in and had it inspected at 6,000 miles. The engine began stalling during deceleration and also had power cutting off during take off. This has been a daily occurrance since that time. …”

“2003 Mustang mach 1 has had shifting problem since I bought it in sept 03. Ford supposedly has been aware of this problem for a year or two. They have yet to come out with a TSB. The car is difficult to shift, especially when temperature outside is cool. Because it sometimes takes 2 or 3 seconds (or more) to shift into the next gear the car is just coasting upon leaving a stoplight and I have almost been rearended numerous times because the trans won't allow quick enough shifts. Car only has about 3,500 adult driven miles, 2400 of which are highway. …”
