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.

Please consider a new requirement for all new vehicles produced that are equipped with a rear liftgate/tailgate, such as crossovers, SUV's and mini-vans. There is no way to open the gate from the inside. There needs to be a latch to open all gates from inside the vehicle in case it becomes the only way out in case of fire or if sinking in water.

Crashed straight into the back end of a vehicle doing 60 while I was doing atleast 80, or 85, maybe more, I don't remember. The first thing I remember seeing is realizing I'm alright despite the blood in the cockpit and on my face despite sneezing which was spreading blood. Is this a vehicle defect or what? my math says that crashing at 85mph into a vehicle doing 60 is like crashing into a brick wall at 25mph. I've had a local mechanic check it out and he says according to his obd-II computer everything is working fine (or was atleast) :) anyways, please feel free to contact me again with any more question you may have.

Trailblazer 6-cyl

  • 700,000 miles
I bought my 2005 Trailblazer new in 2006. The rear driver side door quit working and I had to use a bungee cord to keep it shut until I got it in to a mechanic to look at. I was told that somehow water got inside the door and damaged the components mechanic was able to get the door to shut but warned me if it was opened again it may not shut so it has been duct-taped up so my children won't inadvertently use it. I noticed rust on the top of the vehicle in front of the moon roof very early on. The rear passenger door has to be opened gently from the back portion of the handle as it appears it is going to break off in the near future. The rear hatch and also the glass portion of the hatch back has now stopped working. It was brought in for an oil change and I asked the mechanic to check it out he was able to get it unlocked a couple times by pressing the auto unlock on the key repeatedly (more than 3 times he said) I have not been as fortunate and have not been able to use the rear quarters now because of this.

I bought my 2005 Trailblazer in August 2008. In October 2008, the rear window hinge adhesive was separating causing the hatch to not close properly. This was replaced by the dealership. Now in September 2010 the same thing is happening. The rear window adhesive has completely disconnected from the hinge and the window does not close properly and has a possibility of completely falling off. When the entire rear door is opened now the hinge 'pops' up and hits the glass. The dealership is trying to find an appropriate adhesive to mend this problem and they say Chevy will not pay for another glass replacement. The first replacement came from the factory with the hinge connected to the glass. This seems like a factory defect. I know there are other Chevy vehicles of different years that have experienced this problem and worse when the doors did fall off or the glass scattered due to the poor adhesive on the hinge. This will cost over $800 to replace if this cannot be resolved and there is no guarantee the adhesive on the new glass will hold and I will have no recourse.

No real events, the hinge became unglued from the rear window, causing the window to become unhooked from the body of the Trailblazer. Because this then raises the window above the roof of the vehicle the wind can catch it and pull it completely off the vehicle when traveling at high speeds.
