2002 Chevy trailblazer 1) check engine light came on. Observed strong gasoline odor and leakage. Vehicle failed emissions inspection. 2) took car for service where they identified that the gas tank's fill nipple had split where it was joined to the tank (stress failure?). 3) I heat-welded the nipple back on to the tank.

Check engine light was on vehicle, computer check said fuel tank has a leak or crack. This is a safety hazard which could cause a fire or explosion and should be recalled. Had to have replaced by the garage at my expense. Research on the internet has shown there have been a lot of these trailblazers with this problem and there should be recalled.

Check engine light came on my 2002 Chevrolet trailblazer (86,000 miles). Team Chevrolet analyzed and advised the gas tank is cracked. This same problem occurred at 12,000 miles but was repaired for free as vehicle was under warranty and there was an alert issued for this problem. However, the alert "policy" ran out at 70,000 miles so the dealership, nor GM will cover the estimated expenses of $850. I protested that this was a known and repeated problem and a fire/safety issue but they are not willing to assist in any way.

I own a 2002 trail Blazer ext. I bought it brand new and I have had many many problems with it. I finally have had it and decided to see if the internet reported any similar problems and to my amazement there are many people out there with the same problems, but here is my story. I have had to have the brake lights electrical system on both sides replaced, molding around the license plate frame repaired, oxygen sensor replaced, sway bars replaced, windshield wiper motors replaced, left side passenger window motor broke twice, gas tank replaced because it was leaking gas and now it is back in the shop once again because the engine light came on and I had the onstar system do an engine analysis and they said something is wrong with my power train. I took it to the dealership and they call to tell me the gas tank is leaking gas and needs to be replaced. I told them I just had it done in October 2003. They told me I could not drive my vehicle. I see there was a recall done on some 2002 trailblazers due to a problem like this, but they say my vehicle is not one of them. Why? I am having the same problems with the gas tank. This is the second one. I am lucky I took it in or something may have happened if it is this dangerous. I would appreciate a response back. Thank you, kathy yates.
