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. Notes: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

Trailblazer 6-cyl

  • Automatic transmission
  • 45,450 miles


During normal operation my vehicle's check engine light came on. The acceleration became sluggish. After stopping the vehicle "putted" and then stalled. After putting the car in park it restarted fine, however this has happened 3 times in the last month. The vehicle is currently out of warrant due to mileage so I have not yet taken it to the dealership but will if it happens again.

While driving obout 25 miles my vehicle stopped without any warning.I put it back in park and tried to started nothing happen. Called the dealer they sent a towed truck and said it was the ignition switch and replaced it. I dont feel safe in this car any more.a car that stops suddenly while driving is very dangerous.

Since January of 2005 my 2003 trail Blazer has been blowing the ignition fuse every time I start my truck. It will try until I turn it off and than no power. When this happens my turn signals go out, and my gauge goes hay wire. I thought it had to do with my remote start, and I had that completely removed. Now it does it more often. I took it to the dealership, and they charged me $20 to put a fuse back in which I told the dealership that is what I have to do to get it started, but it will blow again. Before I left the dealership the fuse blow the service manager just came out and replaced the fuse again and did not care that it was going to blow again. He basically just wanted me to leave the dealership. Guess what before I even turned out the fuse was blown again. When I dropped it off they were suppose to figure out what was causing this to happen, but they said they replaced the fuse, and it was fine. If I wanted them to look into it further it would cost $300. Just to look at more. I am pretty much at a loss because my vehicle is over the miles, but is only a 1 and a half years old. I don't know what to do. I think it was really bad that before I left the dealership I had the same problem, and they were fine with letting me leave.

I have had the exact problems as stated in 10047425. Windshield wipers went out completely on a rainy day, module replaced, A/C broke on a hot day-fixed, power steering assist stopped working completely making driving the vehicle nearly impossible, vehicle started on reserve power when temp hit -6 degrees, heater motor stopped working completely the next day -10 degrees. Basically this vehicle doesn't like changes in weather.

Consumer was trying to accelerate but vehicle would not move, and then stalled. Consumer was able to restart the vehicle, and drove it to the dealer for analysis. However, the mechanic was not able to resolve the problem.
