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: It would be ill-advised to blaze any trails with the 2004 Trailblazer. Its faulty fuel gauge could leave you stranded.

2004 Chevrolet Trailblazer Owner Comments

problem #1

Jun 202004

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 2,200 miles


I have a 2004 trail Blazer ext. At about 2200 miles the cruise control stopped working, and when I got an appointment to take it in, they told me, that in fact it wasn't an issue with the cruise control, that there had been a short in the torque control converter solonoid which was a problem with the engine. They had a part overnighted to alderman's Chevrolet, who fixed it quickly and made sure I had a rental while it was in being fixed, but a week and a half later, the same thing happened again. I am taking it in tomorrow, but I am afraid there is going to be permanant damage to my engine because this thing when broken affects the shifting of the engine. I am wondering if I just got a lemon or if this is a common problem with these vehicles. It only has 3500 miles on it, it shouldn't be in the shop twice already for repairs.
