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 Cadillac DeVille Owner Comments

DeVille 8-cyl

  • Automatic transmission

I have been having problems with this vehicle from day one if checked cadlliac records, it will indicate as a brakes problem. 1 had 4 brake jobs done on the vehicle to find out later that it was not the brake, now they said it was the wheel beariing, which sound the same as when they told me brakes. The vehicle failed inspection in Delaware because of the emmissions system, at that time the vehicle was covered by warranty. I assume Cadillac fixed the problem to find out later they never replaced the catalytic converter. I have had many conversations with Cadillac with no help, they gave me a voucher toward a new vehicle which was not going to help me with my situation. Because no one wants to buy a vehicle that has problems from the door, please someone help me to get my problem resolved, I'm tryng to get my vehicle fix, so I can upgrade,
