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.

Door paint start to bubble this fist was notice after I hit the 1,000 mile marker. The paint was repaired by the dealer. Then 3 years later the paint bubble again on all my doors and the back hatch and front hood. It was then repaired by the dealer. 3 years went by and the issue is back the dealer states they do not know why it keep doing that and is unable to fix it again. I feel this is a paint issue with GM. My 2005 Trailblazer was having the same problem with the paint around the doors. I am now stuck with a large cost to get this repaired again due to an issue with the paint that I been dealing with since I first bought the truck.

The rear center brake light cover assembly located above the rear hatch fails. I need to have it replaced. I have already had it replaced once. This will be the 3rd one that will be on this vehicle. Currently it is off. I can not take a chance on causing an injury accident to someone because it can blow off the back of the vehicle. My sister has a 2005 model and has also had hers replaced. Hers did blow off and shattered in the roadway.

Trailblazer 6-cyl

  • 91,000 miles
While attempting to get my son from the vehicle, the left rear passenger handle assembly pulled away from the door housing and into my hand. The linkage remained intact, so I pushed the handle back into place and luckily was able to open the door from the outside. Upon borescope review, the mounting bracket to which the handle fastened was so badly corroded that it disintegrated when I closed the door and dropped to the bottom of it. Mind you now that this corrosion took place inside the door housing as the door handle assembly is not sealed whatsoever from the exterior elements (and GM wonders why the recent door.window switch recall occurred). Upon review of the right side rear passenger door, I noticed the same rust staining below that handle (vehicle is white, so contrast is good) so it is likley only a matter of time before that fails as well. I contacted Chevy, was assigned a case number & took the vehicle to the dealers for required assessment. Was called the next day by Chevy and told they are aware of the problem, however they could not offer any assistance "due to the nature of the climate where I live" (northeast). I questioned their rationale and asked them if they sold specific vehicles to ne customers - their reply was "no". I again reiterated that the corrosion took place on the inside of the door, not the exterior - however the scripted response from csr was the same. I strongly urge NHTSA to investigate this problem further as it is a definitive safety issue in event of an accident in which my children would have to be rapidly extracted from the vehicle and the first responder is sitting there with a faulty handle in his hand. Yes, they could break the window, but try telling a 1 & 3 year old to close their eyes and turn their head and see if compliance is attained!

At 33,000 miles the Chevy bowtie emblem on the rear of the car was replaced under warranty, at 35,000 miles the front one was replaced. Both had deteriorated on their own. Now at 49,000 miles they are deteriorating again. These should still be replaced at dealers/GM cost.

On Friday, May 22, 2009, I had my 2006 Chevrolet Trailblazer serviced at the classic Chevrolet dealership in grapevine for replacement of the fuel tank sensor (which appears to be a manufacturer defect as well). At approximately 6:00 P.M., I picked up my vehicle at the dealership. When my daughter and I got into the vehicle, the air conditioning was set to the highest fan setting with the temperature set to 60 degrees. I reduced the fan setting to ¿auto¿ and raised the temperature setting to approximately 70 degrees. Less than five minutes and approximately one (1) mile from the dealership, the rear glass window of the vehicle spontaneously exploded. At the time of the incident, I was traveling approximately 15 ¿ 20 miles per hour and there was not a vehicle in front or behind me. The noise and mess scared my daughter in the back seat and luckily, the glass did land on her. I immediately pulled over the vehicle to examine the damage and check the street for any objects that may have caused the damage. Upon finding none, I returned to the dealership prior to there closing at 6:30 P.M. upon return to the dealership, the service technician offered to provide a quote the next morning for replacement of the glass, and could not provide any possible reason for the incident. Upon leaving the dealership, I returned to the scene of the incident in order to examine the area more closely for a possible clue to the reason for this occurrence. After examining the street, the shoulder of the street and surrounding area closely, there was no evidence of the glass shattering from an external object. Pieces of glass were on the street and surrounding areas up to twenty feet from the location of the incident. The next morning, I removed items stored in the rear of the vehicle and removed the broken glass, piece by piece. There was not a single object in the vehicle that could have caused the window explosion. This has occurred in other GM vehicles over the years.

I have seen the news when the 5 high school seniors in New York, May 2008 I believe, were killed and then just 3-4 weeks ago, Oct 2008, the news reported a young mother was killed out West. Both accidents involved a front end collision and both where mid-size GM SUVS (Chevrolet Trailblazer, GMC Envoy, Buick rainer). Both accidents resulted in fires and deaths. The news reported the fire was to intense to attempt a rescue in the New York case. In the case out West, the young mother's two children were rescued, but to the intense fire she was unable to be rescued. I would like to know if there have been any other complaints or comments on this or if it was ever reported to this Agency. I have a 2006 Chevrolet Trailblazer as my main vehicle and would not want it to have some unknown defect that may cause my or any member of my family a loss of life. Thank you for any information you can provide.
