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.

: the contact stated that while driving at 40 mph, the brake pedal pulsated during a normal braking situation. The vehicle was taken to a service dealer on three separate occasions, where the dealer turned and grounded the rotors. The repair only worked for 2500 miles.

I have an ongoing and unresolved issue with the brakes on my 2004 Grand Prix. The brakes have squeaked when stopping since the car was purchased in August 2004. I have taken the vehicle to the dealership several times for service. Initially the rotors were resurfaced and the brake pads replaced. After about 500-1000 miles the brakes begin to squeek again. After a call to Pontiac by my local dealership, they were told that they are aware of the issue but have no resolution. Since that time the dealership has completely replaced the brakes and roters and the problem still exists, squeeking when stopping about 70% of the time. I am concerned that the design defect results in a safety issue in the brakes performance.
