Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 555,802 miles
Since July 2006, mileage 49,000, we have had our check engine light come on many times for the same code. After many trips to the garage, and many things replaced, on Jan 31, 2007, mileage 55,802, the dealer told us that I should not drive it home as it could be a fire hazard as there were cracks all over the top part of the gas tank by the filler hose. A new tank was put on and cost came to $832.74. I spoke with customer service at GM and they said GM would do nothing for reimbursement. Since then, I have seen many vehicles posted on the web that have had to have there tanks replaced. If this is a safety concern and fire hazard, why is this not becoming a recall, and why is GM not being held responsible for any of this? I don't think a vehicle with 49,000 miles on should have to have a tank replaced. Thanks for your time.

My 2003 Trailblazer ext smell of fumes. I took it to the dealership in the first case they told me that I need a new gas top and a seal. The check engine like came on again this time they tell me that the fuel tank at the sprout has a leak and I need a new gas tank.
