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: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

2005 Chevrolet Trailblazer Owner Comments

problem #2

Nov 112006

Trailblazer 4WD 8-cyl

  • Automatic transmission
  • 28,000 miles


- on November 11, 2006 the contact was driving at 5-10 mph on wet road conditions when the contact lost control of the vehicle. There were no warning indicator lights displayed on the 2005 Chevrolet Trailblazer. The vehicle started spinning, the contact's vehicle hit a cement median, and the vehicle spun around again. The left front tired looked shredded. There were no injuries. The vehicle was towed away. The drive shaft was replaced. The contact stated that once the vehicle was repaired the tire was rubbing on the frame. The contact took the vehicle to another repair shop and was told that the drive shaft had been installed incorrectly, causing the tire to rub on the frame. The first dealer did not tell the contact they replaced the drive shaft. The vehicle's drive shaft has been ordered and the contact is still driving the vehicle. The vehicle had approximately 28,000 miles at the time of the failure. The contact has the repair invoices.

Trailblazer 6-cyl

  • Automatic transmission
  • miles
Headlights flickering completely off and on in the dark and daylight hours as well as completely quitting. Had it to dealership 2 times for this matter and they could not find the cause of the problem. I felt it was a hazard driving it this way being. It also happened at night. This started in November/December 2005. Haven't had it a year yet and already the driveshaft has been replaced. Is this a lemon ?
