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.

problem #2

Aug 232013


  • 100,000 miles


First incident: (23 August 2013) driving to stop at stop sign at approximately 15mph, vehicle turned off without any warning lights. Second incident: (26 August 2013) driving on highway going close to 65 mph, once again vehicle turned off without any warning lights. Had to turn hazards off and coast to safe zone while cars were passing me going 65-80mph. Third incident: (28 August 2013) driving close to 50 mph, once again vehicle shut off without any warning lights. Once again had to coast to the median and hope not to get in a car wreck. All 3 of these incidents happened with my 2 year old daughter in the vehicle. I have also done research through various forums and websites. It happens without any warning at all and from what I have read there is only a temporary fix by changing the ignition switch but months later it comes back. The only thing that you can do (from my knowledge) is let it sit for an hour or 2 and then it starts up fine, but when your driving at 70 mph the last thing you want is for your vehicle to completely shut off on the highway. There are thousands of people in the exact same situation as me hoping the next time they get into their vehicle they wont be in an accident. Thank you for your consideration.
