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.

2003 Chevrolet Impala Owner Comments

problem #3

Impala 6-cyl

  • Automatic transmission
  • miles


The contact stated the door locks were making a clicking noise and the doors would not lock. When he tried to lock the doors, they would slowly unlock. The battery died before he took the vehicle to the dealership. The dealership found the BCM, and the battery needed to be replaced. They state it was because the vehicle was not driven enough. The vehicle has been repaired, and there have been no further problems.

My battery has failed three times in less than three years and has had to be replaced. I have been stranded twice having to wait over an hour to get assistance. Each time I take the car into the dealer they say they can't understand why the battery would fail so soon and then they put in a new one.

Impala 8-cyl

  • Automatic transmission
  • 25,500 miles
A 2003 Chevrolet Impala with 25,500 miles, the battery corroded through at the positive terminal. Acid leaked from the battery down to the bottom of the car. In talking to the manager at sears, where I had the battery replaced, 8 out of 10 ac delco batteries that they replace, fail this way. In talking to Chevrolet service managers, they see this quite often. I was told that ac delco now has batteries made off shore. How long before critical systems are affected?
