Smell of gas developed around vehicle at all times. Had it looked at and nothing was found. Brought it to another shop and they dropped out the fuel tank, finding the top of the tank wet with fuel and the connection rusted. The solution was to replace the fuel pump and parts.

I am the owner of a 2003 Chevrolet Trailblazer ext, I purchased the vehicle new from GM. In the last year my ses light has been coming on, I took my vehicle to an auto parts store and they analyzed my vehicle to read the code causing the ses light to come on. I had a leak in my fuel tank emissions system. They recommended I replace my fuel cap to fix the problem. Over the past year and after replacing the fuel cap, the problem would go away for a month or so and they reoccur. I took my vehicle in for a system check of the fuel system. My mechanic performed a smoke test on the fuel system, they told me they found a fracture on a weld with the fuel tank, furthermore they said there was problems with the Chevrolet trailblazers with faulty welds on the fuel tank. I searched the internet and found auto forum board stating GM has known about this problem for a while. Talking with a co-worker about my problem, he stated he owned a 2003 trailblazer and recalled receiving a notice from GM about this problem, he gave me a copy of his notice where the notice talks about fracture of a weld on the fuel tank and Chevrolet providing owners with an extension of repairs for 10 years of ownership or 150,000 miles. I never received a notice from Chevrolet about this program. I called the Chevrolet customer assistance center, where I told them what happened with my vehicle; I also told them I had 167,000 mile on my vehicle. They told me they first needed to verify the crack by a GM dealership mechanic. They also told me I had to pay for the fuel system to be check and there might be some consideration for them to pay for the repair if it was indeed a crack in the fuel system. The crack was confirmed by the Chevrolet dealer, but they told me since my vehicle had over 150,000 miles they would not pay for the repair of my vehicle. The fuel tank is a static system, it should not wear out, I feel GM designed a faulty product and should repair this crack at their cost. Please help me.

About a month ago I started to smell gas vapors when I drove my car. One day I was on the highway and a person next to me honked his horn and told me that he saw gas leaking under my car. I was near pep boys and pulled in the parking lot. I shut my car off and looked underneath it. I saw a lot of gas dripping from under my fuel tank and falling onto the ground. I went inside pep boys and told them the problem. It was nearly closing time so I left the car overnight and called for a ride home. Pep boys called me the next morning and gave me an estimate of $270 just to drop the tank and look at what may have caused the leak. They said it was likely a bad fuel pump or bad fuel lines. I asked them another estimate on how much it would cost to fix my gas leak. They said it would cost around $600 to $800 to fix my car if the fuel pump or bad fuel lines were really the problem. I told them to not work on the car and said that I would pick it up. So I towed the car back home and pulled it into the garage. This is the first time that my car has leaked gas. The next day I took off the fuel tank to check where the leak was coming from. When I looked at the top of the tank, the fuel pump was corroded and there was gas on the outside of the pump. Also when I took the tank off, the filler neck hose was cracked and was not connected to the gas tank. I called a junk yard and ordered a fuel pump for $150. I also called my local dealer and told them my issue. They said that my car had too many miles on it and was not covered by warranty anymore. Since the dealer could not help me, I called General Motors customer service and issued a safety defect on my vehicle. They said that there was a extended special coverage on my vehicle that might cover the repair. I called another dealership and I am waiting for them to call me back. Right now my car has been in the garage for almost a month. The only way to fix it is to buy a new gas tank for $500.

The contact owns a 2003 Chevrolet Trailblazer ext. The contact stated that whenever the vehicle is filled with fuel, the sensor that indicates the tank is full fails to work. As a result, gasoline overflows and leaks from the tank outside of the vehicle. Since December of 2008, the vehicle has been repaired four times, which included a fuel tank assembly and tank replacement. The VIN was unknown. The current and failure mileages were 55,000.

I filled my gas tank on my 2003 Chevy Trailblazer ext. And got a gas smell, shortly after the check engine light came on. There is a leak in the fill and fuel pump area I guess. I was referred to see if there were any recalls for this defect and came across this. The garage did a temp. Repair with silicon that only lasted 3 weeks. Now the same thing is happening. I would have to change the entire gas tank to fix this issue.

Began to smell fuel from the rear of my 2003 Trailblazer ext. I had received a letter from GM stating the filler neck some times cracks and would be fixed without cost. I took the vehicle to my dealer, they dropped the tank and said the fuel module was corroded and they would replace the tank but want $625 dollars to replace the fuel module. And will not release my vehicle. I told them to put it back the way it was and they said they can't.

I have a 2003 trailblazer with 73,000 miles on it. Just recently we are smelling gas fumes really bad to the point it makes us sick and is also hard to deal with one car having to be dropped off at work, etc. I have 3 children and have parked the vehicle because number 1, I feel like this is a big safety hazard for my children and number 2, I cannot afford to repair this after reading all the comments on the internet ($900.-$1000. To repair). It sounds like there are a lot of people dealing with the same thing. Can you tell me where to go with this situation" am I suppose to contact GM, and if so are they doing anything about this problem" thanks, sandy nosker
