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.

I was heading West on coliseum blvd and went to accelerate to pass a slow moving vehicle when my accelerator pedal got stuck on the carpeting!!! the engine was bouncing off the rev limiter before I even realized what was going on. This car should have never been released to the public like this since there is obviously a defect with the carpeting since all of my friends with 03 cobra's have all had the same incident occur. Something needs to be done to address this problem because it's going to get people killed.

I am having the same problem as recorded in the current ntsa investigation number PE05038 where accellator pedal stuck wide open due to carpet interference for Ford 2003 Mustang convertible GT. This happened on 7/22/05 and 7/13/05 and once in 2004 on 8/17/04

Accellerator pedal sticks down (at full throttle) because it gets entangled in factory carpeting that is incorrectly installed or attached at time of manufacture of vehicle.

I have a 2003 Ford Mustang cobra that had the throttle get stuck in a wide open mode that could only be stopped by turning the key to the off position. This was extremely scary as I almost rear end another car.

The consumer stated that the accelerator stuck on 2003, Ford Mustang. Consumer was parked in a parking lot when he put the car into reverse and backed up. The motor started racing, and the accelerator stuck while the driver was backing, and he crashed into a moving car. The police came and wrote the consumer a ticket for improper backing, but did not write a police report on the accident. The owner had no prior problems with the vehicle, but the owner has only owned the car since April 10.. consumer was still driving the car. The owner has not had the car checked for any malfunction. Consumer has not talked to the dealership, or the manufacturer. Also, here was no insurance report on the accident. The owner was traveling at a 10 mph when the accident happened. Owner planned to have the car looked at today for cosmetic damages, and the accelerator checked. There were no injuries to report.

2003 Ford Mustang svt cobra owner web sites are widely reporting this dangerous problem as well. See internet link: <>. amazingly, the gas pedal appears to be cheap plastic and it fractures quite easily without warning. Broken parts get stuck under pedal and foot. Nlm
