Trailblazer EXT LT V6

  • Automatic transmission
  • 125,000 miles

Well after 125,000 miles it finally happened to me as well. Like some others, the hatch cover flew off my car on the highway going 65+ MPH. Thankfully the car traveling behind me was able to avoid getting hit by it. After researching and hearing from others, I can not believe that GM has done nothing about this. This is clearly a safety issue if these are flying off the car. I hope I have no problems driving around with out it as luck would have it my husband lost his job just a few days before this happened and has been unable to find this used as the junk yard vehicles are missing the cover too! For those with the same vehicle, in the past year, the drivers side power seat panel broke, the AC lines busted in the rear and the gas gauge has stopped working. Just forewarning and good luck...I am selling mine as soon as we get this fixed.

Trailblazer 4WD EXT V8

  • Automatic transmission
  • 94,400 miles

I noticed an odd thumping sound while driving at highway speed. When I pulled over to investigate, I discovered that the rear hatch cover had broken loose on both ends. I continued very slowly to the next exit where I was able to purchase some duct tape in an attempt to hold it on and continue to my destination. Three miles later, the part broke loose and flew from the car. It was a miracle it missed the vehicle behind me and went sliding down the berm. The lighting fixture was still hanging from the wire, still attached. I was told that if I could find the part at a junk yard, I could save some money, but it appears so many of them never make it that far, that I'm outta' luck.

I've read where this is due to snow and ice build-up, but we've had an extremely mild winter so far with very little snow. A friend at church has lost her rear hatch cover twice. The first time was within the first year, so GM covered that repair. This is obviously a very serious design flaw that GM should acknowledge and repair at no cost. They are fortunate there haven't been any know accidents, injuries or law suits related to this issue.

Trailblazer LS V6

  • Automatic transmission
  • 54,952 miles

I opened the hatch when there was snow on top of the car and noticed a spungy resistance. After clearing off the snow I tried again, same thing. so with the hatch only slightly opened I looked up and found the problem. The Ice on the roof prevented the trim pannel from moving properly and caused the cheap little plastic clips that hold it to the hatch hinges to break!

When I called the dealer he told me the price right away. He said he had just fixed one that morning and generally does about 30 every winter!!!!

Remember when you scrape your windows to climb up and remove the ice from the top of the hatch before opening. This should be covered by a TSB

Trailblazer EXT V6

  • Automatic transmission
  • 70,000 miles

Rear hatch cover out of no where just flew right off the back window. Could have really turned out bad had someone been behind us, luckily no one was. Have been calling around to try and find a replacement for it and every mechanic/wrecker i have talked to says this happens all the time on these vehicle. I think GM should be responsible to fix it right and cover all costs, regardless of how many kilometers are on it. This is a dangerous thing, and for the price of these trucks, seems ridiculous that something could just fly off at any time. So far with pricing, the part alone is $560/CDN, but thats primed, not even painted or installed. Seems like a lot of money to pay for something that is probably going to fly off again.

Trailblazer XT V6

  • Automatic transmission
  • 48,467 miles

This vehicle obviously was not intended to be used in a northern climate. The first time we experienced a significant amount of snow and freezing rain this past winter (freezing rain is common in southern Ontario) the fibreglass hatch cover on the rear tailgate snapped off. The ice must form under the cap and when the rear door is opened, it causes the cheap mount to give way. We sought help from our dealer, but were told that it was not their problem. Have heard that from GM before. We were told that it would require a $700+ fix (parts and paint) and that we would be responsible for the full cost of the repair. Our neighbour has the identical vehicle, the identical problem, received the identical lack of help from GM and is also driving around with duct tape holding his GM product together. I've seen many others with the same problem in our area. THINGS LIKE THIS SHOULD NOT HAPPEN TO EXPENSIVE VEHICLES. They don't seem to happen to my Mazda's...

Trailblazer EXT V6

Rear hatch cover, exterior hardware surrounding third break light, falls off without warning, even when vehicle is in motion. GMC blames and attributes this problem to ice accumulation instead of fixing their poor design and does not take responsibility for correcting the problem, endangering all motorists.
