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.

The gas pedal on my 2004 Ford cobra stuck all the way down and almost created an accident. I was very fortunate to have not been injured or to injure someone else. Ford, this should be a factory recall period.

2004 Ford svt cobra Mustang the throttle pedal will hang up on the carpet when at full throttle. When the throttle hangs, the engine will rev until redline, and then the rev limiter will set in. To stop the car, the driver must kill the ignition switch (being carful not to turn it so far as to lock the steering wheel) and bring the car to a stop without power brakes and power steering. With over 390hp in the svt cobra, a stuck throttle will cause this vehicle to approach others at a very rapid pace. To fix the problem, a 3"X3" piece of carpet must be cut from the floor beneath the accelerator pedal.

A stuck wide open throttle occurred while driving my 2004 Ford svt cobra Mustang... fortunately I am an experienced driver with some auto racing in my background... I was able to quickly push in the clutch(engine was bouncing off the rev limiter at this point), and turn off the key... the cobra Mustang has hydro-boost power brakes and power steering so at this point, steering effort and brake pedal effort "went through the roof"(were very high). Since I am an enthusiastic supporter and buyer of Ford products I would like to see a recall on this very common problem... before some one less experienced gets killed!!! these are very powerful cars!!! things happen extremely fast when the pedal is down!!! the cause of this stuck throttle is a partial bending of the accelerator pedal, and the contact with and sticking under of the carpet by the pedal. A stuck wide open throttle in any car is very dangerous!!! a stuck wide open throttle in this particular car is insane!!! to correct the problem as soon as I arrived home I trimmed the carpet that was contacting the throttle when down... so that it would no longer touch at all. Please note---> at first I thought that the floor mat had caused the problem. I was wrong... while still possible if dislodged from it's anchor point... it was not what was sticking the pedal... it was the carpet, which was shaped poorly and retained even worse in that critical throttle area. Please notify the proper authorities as to the potential for extreme consequences this defect presents. Please note that the date in the date field is a guess since this occurred over a year ago... I am filing now because I have read about numerous other instances of this occurring and I find it very troubling.

I own a 2004 Ford Mustang cobra. On the day listed below, I entered a very busy freeway in phoenix and had to give full throttle in third gear in order to merge into an opening. When I went to release the throttle as I moved into the opening, the throttle stayed at the wide open position with the pedal still to the floor. I had to push the clutch in, hit the brakes hard, and shut the engine off to avoid hitting the car in front of me. It was close. Then I had to negotiate a safe exit to the side of the road. What I found was the throttle pedal was stuck under a piece of the carpeting. I have found this is not an uncommon occurance in this model. (Mustang) I can probably give you the names of 25 people who have suffered this problem. Please!! this is a huge safety issue. Please do what you can to resolve this problem. Again, this is not an uncommon problem and I would be happy to direct you to a forum where you can see many instances of this. Thank you for your time.
