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.

2004 Chevy Impala - ABS light and trac off light have intermittently going on and off, then the speedometer started to become inoperative, now the tachometer goes haywire and is stuck over the max. I have read that there are countless complaints of the same nature.

Collision on the interstate. I was driving approximately 45 mph when I struck the vehicle in front of me. Traffic was heavy and they slammed on their brakes. I had the brakes all the way to the floor but the car did not stop. Their car was completely stopped when I hit them and knocked them into another vehicle. My air bags failed to deploy. Body shop owner stated that it appeared that the wires to the airbag had been sliced during the accident. Front bumper, hood, and fenders had to be replaced. Radiator and condenser had to be replaced. Body of the vehicle had to be squared. Rotors and brakes replaced.

After purchasing vehicle took it back to have steering checked because it did not feel or sound right when doing a braking and turning steering wheel combination. Mentioned the NHTSA recall of 2004 Impala. Was told did not involve ss. On this occasion was unable to stop the vehicle, unable to steer properly, could not control vehicle. It spiraled and hit a bus stop/pole.

The contact owns a 2004 Chevrolet Impala. The vehicle caught fire in the dashboard area and then spread to the hood. The fire occurred two to three months after the vehicle was purchased. A relative sustained injuries to the hand due to the fire. The cause of the failure was electrical. There is no fire or police report. The vehicle was repaired, but the contact does not know the specifics of the repair work. Three months after the repairs were completed, the check engine light illuminated and the vehicle began vibrating when the brakes were depressed. This failure occurred while driving 20 mph or more. The brakes and the disc were replaced and aligned. The failure continued to occur and the brakes were replaced within a month. The mechanic stated that the disc failed which caused the brakes to fail. The contact detects the smell of fuel within the vehicle. The fuel gauge has failed to operate normally since the repairs were performed. The fuel gauge indicated that the fuel level was full; however, the engine shut off and there was no fuel in the vehicle. There was also the presence of fuel on the ground after adding fuel to the vehicle. The dealer has not diagnosed the cause of the fuel gage failure or the odor. The inspector stated that the vehicle may not pass inspection due to the fuel odor in the interior. Although the brakes were repaired twice, the vibration continued to occur. The engine size was unknown. The contact can provide receipts for all of the repairs that were performed, including an insurance report. There is no fire or police report. The current mileage is 81,000 and failure mileage was 45,000. Updated 08/15/07.
