40 Tank Assembly problem

Failure Date: 07/14/2007

The check engine light kept coming on and they replaced a sensor and had me buy a new fuel cap which didn't fix the problem. I had taken my vehicle to the dealership 5 times before they correctly diagnosed the problem as a fuel tank vapor leak. The only way to fix this is to replace the entire fuel tank. My vehicle has been in the the service department for the past 3 weeks and the fuel tank is on national backorder. I have been reading about this being a problem on the Trailblazer ext. On many websites and blogs. It seems that this would be of a huge safety concern.

41 Tank Assembly problem

Failure Date: 05/09/2007

In the 2004 Chevrolet Trailblazer engine check light stayed on. Unfortunately, none of the 10 Chevrolet dealers we took this vehicle to could diagnose the problem w until we were past the 70,000 miles extra warranty Chevrolet added to cover all the vehicles with this problem. Warranty information was addressed in special policy adjustment- fuel tank inlet check valve fracture #05012 on March 14, 2005. Apparently, as we were told by a Chevrolet dealer this vehicle had a fracture in the gas tank, and the only way to fix it was to replace the tank. There was no recall on this problem, but I have found number of articles of people complaining of the same problem on the internet. This was a huge safety issue, especially for us, as this vehicle was the primary transportation for my children to and from school.

42 Tank Assembly problem

Failure Date: 02/01/2007

I have a 2004 chevy Trailblazer lt. On the gas tank where the fill neck is connected to it, the seam is cracked and leaks gas. I have tried to have the tank repaired but with no success. I have contacted gm and visited a chevy dealership about this concern and they want me to pay $1,300 + plus change the tank. This vehicle has not been damaged in a wreck. This is simply a defective part that causes a huge safety concern for me. I have read of other Trailblazer gas tanks cracking at the same location that resulted in a campaign to replace them. I think that gm should replace these tanks that crack before they result in a fire and cause damage or injury. Gm and the dealership have demonstrated no concern for my safety and that of my family. I feel that this safety issue should eb dealt with by the manufacturer. Thank you for your time.

44 Tank Assembly problem

Failure Date: 07/01/2004

My complaint is regarding a potential incident. I own a 2004 chevy Trailblazer. I bought this new in 2004. Within 3 months, I smelled gas from inside the truck. Then noticed when I fill the tank, it leaks out of the top. I brought this to gm attention and they said there is no recall and that I would be responsible 100%. Could cost up to 1000. Can you please investigate the issue and determine if there are others out there like me? I beleive this is a lemon type issue and I am planning to have my attorney take action but wanted to get your feedback?.
