Gas tank leaking. I have two children (safety issue) I think there is something that GM needs to do about this problem.. obviously it is a problem. I guess we need to take further actions ourselves.

I got a strong smell of gasoline in my 2003 Chevrolet Trailblazer. I stopped at a garage and they looked at it and said the fuel line was either busted or corroded. They could not fix it right away, but said they didn't think the fuel line on a 2003 vehicle should be rusted. The gas was pouring out underneath the vehicle causing a fire hazard. I called the local Chevrolet dealer and they could not fix it either, but they informed me that it would be rusted through that they are replacing a lot of them and also brake lines. I ask if there was a recall for this on the vehicle, and he said no it's just the ice melting materials they use on the roads around here. The gas tank has to be removed and the lines need replaced. The garage that is doing the work says that the fuel pump and filter should be replaced while the tank is down. I don't believe a four year old car should have fuel lines and brake lines rusting out like that. I think it is an engineering mistake on the materials these lines are made from. I am sure a lot of other people have spent large sums of money to repair this problem and if my complaint can get a recall started that would benefit all Trailblazer owners.

Chevrolet 2003 Trailblazer: Noticed a large puddle in driveway, which was gasoline. Started SUV up and the gas just poured out of the vehicle. I was afraid to drive it, but knew I had to do something. I drove it to the nearest repair station, wherein, after inspection it was found to be rotted supply and return lines on fuel pump module. The repair station removed the remaining fuel from the fuel tank; replaced fuel pump module; reinstalled fuel tank; reinstalled fuel. At a total cost of $778.14 used. I am a GM retiree after 33 years of service, and would like to be reimbursed for said amount of money. Thank you for your consideration in this expensive matter.

The gas intake pipe allows gas to spill out when fueling 2003 Trailblazer.basically, the fuel pumps at all gas stations I use do not shut off when fueling and gas overflows onto the ground. The dealer has ordered a replacement part but no recall is out. This is a fire hazard and safety concern.
