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.

Trailblazer 6-cyl

  • 114,000 miles


While driving down the road in my 2006 trail Blazer I had a door switch/latch malfunction. In my vehicle when you pass 15 mph the doors automatically lock. At that moment the doors switched to locked and at the same exact time the door lock/latch failed and the door opened while the car was moving. I made arrangements with my local Chevy dealer via Chevy customer care to correct a recall with the door switch. When I received my vehicle back the door latch/lock was not fixed. That part wasn't under recall. The part that failed was the door lock actuator which is an electronic device that is part of the door switching/locking system. The fact that the door switch was recalled due to shortages is quite possibly for the failure of this latch/lock. I am an avid seat belt wearer, luckily. I am great concerned with the potential for serious injury or death with this failure in other vehicles. I have reached out to the dealer and GM but was told too bad for the dealer and have bad no response when I mentioned their lack of concern for safety. Thank you

I came out to my vehicle today, unlocked the door with the keyless remote but the driver's door was unresponsive. Upon starting the vehicle I realized the windows don't work on the driver's side as well. I removed the driver door control module to find a burn mark internally on the door as well as burnt plastic on the door module itself. The window and lock worked fine the night before so I'm concerned with the short circuit occurring over night without a key in the ignition.

  • 38,000 miles
I hit a bump one day and the interior light popped on for a second and then went off. I eventually realized the rear door was not latching at all, I tinkered with it, tried some wd-40, it does work intermittently, but is getting to the point where its not latching the majority of the time. The 3 bolts holding the locking mechanism and the point where the lock with latch do show signs of corrosion. It appears the 2003 Trailblazers had this same issue and eventually there was a recall. At 38,000 miles I also had the fuel gauge issue and the fuel sending unit is bad.
