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.

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 35,678 miles


The contact owns a 2005 Chevrolet Trailblazer. Two weeks after the vehicle was purchased, the 4-wheel drive failed. When turning left, right, and when driving in reverse, the wheels lock when the 4-wheel drive is activated. The failure also occurred once while in drive, but all the other failures occurred only in 4-wheel drive. The dealer stated that the 4-wheel drive was operating normally. The manufacturer sent a technician to his local dealer to attempt to remedy the failure, but was unable to assist. The technician stated that the failure was located in the 4-wheel drive transfer case. The failure mileage was 35,678 and current mileage was 36,210. Updated 04/22/08.
