I had the gas tank of our Lumina replaced twice at the local garage in
the past 6 monthes. The problem with the original tank, and the first
replacement was that the tank was flexing. When you turned the car
on/off you could hear loud thud noises as the gas tank flexed. After
a couple monthes of this flexing, the tank cracks and breaks. The
Mechanic actually told us that we had to have drove over something
like a rock and damaged the tank. This is obviously not true.
I am now on tank #3 (second replacement). The problem is still
occuring, but now you can hear it flex while driving. The mechanic
claims he sells many of these tanks and has not seen this problem
before. Im up over $1000 already, and I dont know what to do. The
car should have been taken to the GM dealer in the first place, but I
am wondering if anyone here knows of something that could be tried
before forking over another $1000+ to get this fixed at the dealer.
We have put new caps on the gas tank filler and that has not worked.
Has anyone heard of this happening before? Any advice would be
