Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Potentially dangerous situation when 2003 Ford cobra stalls upon deceleration and brakes become inoperable. Almost crashed multiple times. If I get into an accident because of this I will sue forward as they have not recognized this as a problem.

2003 Ford Mustang svt cobra. This is my second 2003 cobra (the first was involved in an accident). Both cobra's have and had problems with stalling, which causes a near complete loss of braking power (the brakes must have the engine running in order for them to work, unlike some vehicles), which is potentially extremely hazardous to my safety, as well as any other vehicle, pedestrian, children, or animal near me. It happens on deceleration at low speeds driving around town. There is a massive amount of documents going on that shows nearly 40% or more of 2003 cobra owners are having the same issues. Ford has updated the PCM 2 times already for the 2003 model year, and the problems still exist! here is a link to a site with many owners reporting the problems:

In December of 2002 I purchased a 2003 svt cobra Mustang from satcher Ford. This car had a number of problems which caused Ford to replace the engine, re-flash the computer, replace clutch. This car had a stalling problem that left me afraid to drive it. When you would depress the clutch, the car would sometimes stall. This would cause the loss of brakes and steering and nearly caused an accident. Ford finally agreed to buy back the car and get me another car, but I am having the same stalling problem with that 2003 cobra as well. Satcher Ford has indicated that they do not have a fix yet. Ford need to look at this problem because it will get someone killed if they do not correct it.

The most recent being just a few days ago, my vehicle will sometimes have a problem in which it stalls while moving at a slow speed while a gear is not engaged. The car is a 2003 svt Ford mustang cobra convertible. A call to Ford's svt division had no solutions. Many people that I know with the same car are experiencing the exact same problem. It has occurred to me 4 times. Thank you so much!

  • Manual transmission
  • 800 miles
Svt cobra is intermittently stalling while the clutch is fully depressed and decelerating to a stop. This intermittent stalling occurs most frequently at idle. The vehicle has stalled at least ten times in the first 1174 miles of ownership. Occurs with greater frequency in warm weather while the engine is hot. Two service departments checked the engine and one reset the idle controller. They could not reproduce the condition, however, the stalling persists with no change in symptoms. Although the vehicle restarts immediately, the condition significantly increases the chances of a collision while trying to regain control and restart in traffic.
