Print this page 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.

2006 Chevrolet Trailblazer Owner Comments

problem #4

Oct 042007


  • 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.

We were involved in a head on collision with another vehicle. Both were traveling at approximately 45 mph. The air bags did not deploy. I was driving the vehicle and have a broken right leg, broken left heel and ankle. I was temporarily knocked unconscious from hitting the steering wheel. My wife suffered a broken wrist, fractured pelvis, and fractured tibula.
