What owners wrote

I purchased a chevrolet ext trailblazer on nov. 26, 2004. 2 months later on feb. 1, 2005 it was towed into the dealership after shutting down 5 times with 2 loud explosions. The malfuction of the vehicle came close to a couple of accidents occuring and an almost near death experience for my daugher and I when it shut down for on a 4 lane highway by attempting to cross it unto the residential area.

Reported at 5,000 miles, February 2005

Due to a service engine soon warning light and smelling gas inside my vehicle, I took my vehicle to my local mechanic. He stated there was a crack in the neck of my fuel tank. The tank needs to be replaced. He also stated that this is a common problem with trailblazers. I then took the vehicle to the GM dealer where it was purchased. Their initial diagnosis was the fuel cap needed to be replaced. At that point I asked them to check for a crack. They did and verified there is a crack.
