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.

Check engine light come one code P0461 - fuel tank pressure sensor circuit high voltage. This problem seems to be a common problem with the Chevy Trailblazers and should be a recallable issue. Furthermore, the suspension on this vehicle has been a financial drain from the sway bar links, front end links stabilizer shaft and ball joints.

After changing the vehicle's battery, the fuel system, air system and 4X4 system have all failed. GMC is aware of my issue and hundreds of others. They refuse to fix this known issue, this vehicle is very dangerous to drive.

problem #1

  • 10,397 miles
The contact owns a 2006 Chevrolet Trailblazer. While driving 50 mph, the vehicle would vibrate. The vehicle was taken to the dealer on numerous occasions, but they could not produce any error codes or provide a sufficient remedy. In addition, the air bag warning indicator would sporadically illuminate on the instrument panel, which signified that the air bag was inoperative. If the passenger sensing system were to malfunction, the front air bag on the passenger side could be disabled when it should be enabled or vice versa. The risk of injury in the event of a crash was increased. The contact had aftermarket leather seats installed in her vehicle and called the manufacturer in reference to NHTSA campaign id number 06V417000 (air bags:frontal). She is currently awaiting their response. The failure mileage was 10,397 and current mileage was 29,439.
