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.

When accelerating at full throttle accelerator pedal gets stuck. This can be a big problem since severe engine damage due to excessive engine RPM's can occur and can cause collision due to car accelerating uncontrollably. The only way to control this was shutting off the ignition but that in itself can be a danger since shutting off the ignition causes loss of power steering and hydraulic brakes which can make the vehicle extremely difficult to steer and brake, potentially causing an accident.

I down shifted my car and floored the gas pedal and the pedal caught on the carpet. I could not get it to release and had to shut off the ignition on the freeway, pulled over, and park the car to fix the problem. Speed of 100+mph was reached.

Gas pedal got stuck under carpet. I was passing someone and the gas pedal got stuck. I nearly wrecked, but was able to pull over. Found the problem, had to cut the carpet so it wouldn't happen again. It is appalling that a poorly designed carpet could cause potential deaths. Fix this!

I was proceeding through intersection on a left hand turn lane driving in the wrong gear for the speed at which I was going(20 mph), I down shifted into second gear and the gas pedal was stuck to the floor for a half a block heading towards the next intersection that had a red light for me. I couldn't stop the car so I turned the key off. After looking at the pedal I noticed the carpet doesn't fit right like it's short and my gas pedal arm is extremely weak and bends towards the transmission scraping the carpet through the range of up/down motion. I think the carpet is half the problem the other half is the gas pedal arm. The right side of the gas pedal rubs the carpet. I pull the pedal off of the carpet every so often within days the pedal is rubbing it again.

The owner was going to leave driveway it took three times to go into gear. Then, when it went into gear, it went about 10-20 feet by itself and crashed into the owner's house. The owner never had foot on the gas pedal. The owner had foot on the brakes the whole time. The owner sustained shoulder injury. Had about $400 in home repairs, about $6000 in car repair, and doctor bills as a result of accident. The owner called Ford, who said it must be an unusual accident, and they had never heard of this problem.

I have a 2004 Mustang cobra and the gas pedal got stuck while I was on the freeway. I had to put the car in neutral and shut off the car. I almost got in an extremely severe car accident and think that Ford should have a class action law suit filed against them or there should be a recall on this problem. Evidently there are many others that have experienced the same problem.

I have read about this issue from other 2003/2004 cobra owners and did not think it was a problem for me after inspecting my car. However, on July 30, 2005 I experienced an issue where the accelerator was stuck on the floor at full throttle. This happened on a city street and could have caused a serious issue if I did not have a large open space to pull off. I was forced to kill the ignition and stop the car. As I am sure you know when doing this you lose all power steering and braking so it is not a safe or easy task to bring the vehicle to a stop. In order to resolve the issue it required me reaching down and yanking up on the pedal with considerable force to remove it from the carpet where it was embedded. While most issues with cars can be over looked this is possibly a very bad accident waiting to happen.

I was driving my 2004 svt cobra, I was in a 55mph zone and went to pass a guy. My accelerator got stuck on the carpet and would not come up, I was forced to shut the car down and pull off to the side to figure out what was wrong. This has happened on 3-4 occasions while I revved my engine also, I have since cut the carpet all around the gas pedal so it will no longer stick. Mike zilinski

I have a 2004 Mustang cobra. Months after purchasing the car, twice I had the carpet near the gas peddle interfere with the operation of the gas peddle. Once it did not allow the gas peddle to return to its normal position when my foot was removed. The second time the carpet found its way under the gas peddle and did not allow for proper use of the gas peddle until the carpet was removed to its normal position. Cause seems to be that the carpet does not stay attached to the tabs that are to hold it in place.

Complaint on my 2004 Ford Mustang GT (orginal owner of both). Vehicle has problems relating to the position of the carpet around the accelerator pedal. After minimal use of the vehicle (5000 miles or around 3-5 months of use) a large hole developed on the right side of the accelerator pedal. If the accelerator is depressed fully or almost fully the side of your shoe can catch on the hole long enough to pose a saftey hazard of not being able to take your foot immeadatly off the accelerator pedal. I have had this happen on several occasions, and have to be very concious of my foot position on the accelerator pedal when driving to prevent this problem now that I am aware of it. Ford deems this problem as normal wear and tear on the car and will not cover replacement of the carpet under my bumper to bumper warrenty. Pictures are available, please contact and I will forward them to you.

Driving on city streets, my accelerator has become stuck in the carpeting twice causing temporary inability to control speed. I tried to glue the carpet down myself, but there was not enough "give" in it to correct the problem.

The contact owns a 2004 Ford Mustang. She is calling in response to the investigation number PE05038. The contact states that the vehicle sounds like it is revving too much while changing gears because the RPM's stay up to high. The contact has checked with the dealership because they thought something was wrong with the car when they first purchased it, and they told him it was the nature of this car. The dealership must have spoken with Ford in the engineering department. Also, they wrote a letter to Ford and contacted them as well about this problem.

I have a 2004 Ford Mustang cobra. I have had the accelerator pedal become stuck under the carpet on more than one occasion. One of the events happened while I was on a dyno-jet testing horsepower, and it was captured on video. The other even happened while driving, and I was nearly killed. I just happened to think fast and switch the key off. I have fixed this by cutting away a section of carpet under the pedal. I am not happy with this solution because this is a limited production car, and cutting carpet is not a thing that I wanted to do. But I was afraid that if I did not do this I would be injured or killed the next time it happened.

2004 Mustang cobra bought new one month prior. Driving down a quiet road, went full throttle for short duration, throttle stuck, I had to turn off the ignition. Accellerator pedal was stuck under the carpet. Took it to the dealer, they said they fixed it, and it happened again under the same circumstances. The dealer finally cut the carpet and screwed it to the floorpan (the repair is not visible) and it hasn't happened since.
