I have a 2002 Trailblazer ext and the gas tank leaks at the filler tube connection.

Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 54,000 miles
The check engine light came on. I took the 2002 Chevrolet trailblazer to the dealer, who determined the gas tank leaked from the top of the tank where the gas entered. There was no way this could occur from wear and tear. This was a defect in the workmanship, product liability. It will cost approximately $800 for repairs.

Found a crack in the filler pipe leading to the gasoline tank on my 2002 Trailblazer ext. First started smelling gasoline, then loss of gas mileage and then check engine soon light remained on.

I own 2002 trailblazer and twice the fuel tank had broken around the filler neck letting fuel leak out. The problem is several other owners have had the same problem. The second time it broke I replaced it my self and I am sure it is a manufacturing defect. If a owner had this problem it could cause fire/explosion.

I have a crack in the fill neck of my gas tank. Very expensive fix on a 2002 Trailblazer ext. Caused a loss of speed on the highway and effects the pick up especially when going up hills, even small inclines.

Chevy trailblazer 2002 ltz - VIN [xxx] there is a crack in the connection between my gas tank and the filler pipe. Chevy told me that currently have a "special policy" #05012 which covers this flaw, however my car does not fall under that even though the symptoms are the same. How can I pursue this and get it fully covered. [xxx] updated 07/18/2012 information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

problem #1

Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 70,000 miles
After smelling gas fumes and having the "service engine soon" lamp illuminated, I took my 2002 Chevrolet Trailblazer ext to my mechanic for service. The attachment from the fuel filler line and the gas tank was loose. He relayed that Chevy was having a lot of problems with this. After pursuing this with GM, I found a special policy # 05012. GM will fix the problem on vehicles with up to 70,000 miles. My vehicle has 72,000 miles. GM refuses to repair this defect.
