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.

I was driving down a curvy road. I looked away from the road for a second and when I looked back to the road I was slightly veering off. I overcorrected the car to my left and corrected back to the right. Once I was back straight again-the side impact airbags deployed. This all happened very quick. I was traveling about 35-40 mph. There was no damage to the vehicle, I did not hit anything and there was no collision. There was only one other passenger in the car and no one was hurt. I called the insurance company who declined the claim since there was no collision or property damage. They attributed the crash to overly sensitive yaw sensors. The insurance company told me they have seen similar occurrences that they attributed to the yaw sensor. I made a claim with Chevrolet, the manufacturer, of my vehicle. Chevrolet sent out a 3rd party engineer/inspector to look at and diagnose the vehicle. The engineer's report said that the vehicle was preparing for a roll over and acted as it was supposed to so there was no mechanical malfunctions. Nothing has been done to correct this situation. The airbags on the vehicle have not been replaced. Chevrolet says the car has no mechanical defect and the insurance company says there was no collision or anything to attribute to why the airbags deployed, other than the airbags being too sensitive.

The contact owns a 2005 Chevrolet Trailblazer. While driving 45 mph, both side air bags deployed without an impact or crash occurring. The contact swerved on the highway, but managed to drive the vehicle to the dealer, where it is currently being inspected by the manufacturer. The current and failure mileages were 74,000.

Was driving on highway at approximately 65mph when we were cut off by another vehicle. We drove off onto the shoulder to avoid the accident and started to slid sideways. As we corrected the vehicle we entered upon the pavement and corrected the sliding vehicle and was continuing to drive straight for about 3 seconds when the side airbag deployed. Tgere was no collision nor was the corrective move so erratic as to tip the vehicle.

: the contact stated while traveling 20 mph, the side curtain airbags deployed without a collision. The contact sustained minor injuries. The dealership was unable to determine a problem, but replaced the airbag sensor with the sensor for the current model year vehicles.
