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.

Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 125,278 miles
1.- electrical system failure in the Trailblazer ext 2002 125,278 miles. Ac delco professional battery maintenance free 19001810 catalog 1810 (replacement 78-6yr) has green hydrometer color but a sense acid smell around. 2.- two business appointments were cancelled and no way to go out with the car. I called the dealership for assistance Friday 18, 7:30 P.M. and leave a voicemail. The dealer return the phone call Saturday 19, 7:30 a.M. later I call back 9:00 a.M. and ask them what they think about and where to start...with the battery?? but they said that they are booked and not able to take any other appointment until Monday....just in case how much would be.. 75 $ plus labor 25 $ total around 100 $. consequences: Two potential business opportunities were lost as well as the opportunity of car enjoyment and freedom. Battery replaced $ $80.99. Acid leaks through the car. Request friend help for time to buy, deliver and replace the battery at home. The ac delco web site said that "the battery that comes with a GM vehicle is covered by the limited warranty of three years or 36,000 miles" it is really not fair how a battery can lose it positive terminal itself and why consumer is not covered against this defect that involve time and money as well as opportunities and major accidents. 3.- Saturday 19, 10 a.M. I called a friend to find another battery. Before that we take out the ac delco battery from the car the positive terminal was completely separated from the case and acid was is unbelievable. The ac delco battery has a green hydrometer indication. The battery was replaced with another brand expenses of $ $80.99 without consideration of timing, driving and gas used by my friend and mine to replaced the ac delco battery that had positive terminal completely separated.
