Five problems related to structure have been reported for the 2006 Chevrolet Trailblazer. The most recently reported issues are listed below.
I had by back hatch open and I grabbed the door handle to close it. I pulled it down and as I pulled it down I hear a pop and all the glass shattered down on me with the door still open up in the air. Three weeks later I replaced the window. (not a cheap glass almost $1000 with labor to replace) the mechanic opened and closed the door and the hatch to test for defects. All went well. I went to close the door so that I can leave the mechanic shop and I heard the pop and the glass shattered again. GMC has no recalls for the 2006 chevy Trailblazer ext LS and I have to go get this back window again. This is a great truck just don't know what is wrong with this back window. Ughhhh!.
The glue that holds the rear window on the vehicle separates from the window, causing the window to blow out. We noticed the window was lopsided so we opened it and found that one side of the window had come unglued. We took it to the dealership this morning and they said it couldn't be reglued - it would have to be completely replaced. Chevy won't cover it because it's out of warranty. We left and he called us with the quote of $1000 for replacement. Just a few minutes later, the entire window blew out. It shattered glass all over the road and vehicle, even hitting us in the back of the head. Luckily our daughter was not in the car. The plastic cover that sits over the top of the window flew off the back and into traffic. There was a car behind us but there wasn't much traffic so they managed to avoid being hit. No one was hurt when it exploded but it could very easily have hurt someone in the back seat or in vehicles behind us.
My 2006 chevy Trailblazer ext is junk! we purchased it used in 06 it had around 20,000 miles it now has 75,000 the front doors make loud popping noises when opened and shut. They are coming loose from the frame.
I have an excessive amount of wind noise around the front windows especially at speeds over 50. I have checked with my dealer, but there appear to be no fixes. I contacted gm but they said they have no complaints and offered no help except to check with my dealer. I tried out a few other Trailblazers and found the same wind noise issue. I saw similar complaints on other web sites, but none are making it here. It appears turning up the radio may be the only fix.
: the contact stated while the vehicle was parked on an incline, the rainwater did not drain properly and went backward into the passenger side of the vehicle. This caused the passenger side floor board to flood. The dealership determined this was how the vehicle was manufactured and should not be parked on an incline.
