I have been smelling a gasoline odor on the side of my SUV where the fuel door/fuel tank is located. Research on the internet yielded many Trailblazer owners reporting fuel tank/sending unit/pump corrosion resulting in a fuel leak. A family member of mine just had this exact problem repaired on a 2003 Chevrolet Trailblazer. I believe this same issue is starting with my 2002 Trailblazer. I replaced the gas cap to eliminate the possibility of the gas odor coming from the tank fill area, but the odor persisted. The odor resembles an actual gasoline spill and/or leak and not just gasoline vapor odor, ie: Filling the tank. Like I stated before, internet research yields many Trailblazer owners reporting this issue and having to pay for costly repairs. Any issue regarding the fuel system/gasoline, in my opinion, should be an immediate safety concern. I have not received any information from GM in regards to a recall bulletin. I am going to conduct more investigation, but in the meantime the smell of a gasoline leak is unmistakable. I hope this information is helpful and I hope that a recourse regarding this issue and its repairs can be formulated. In the meantime I feel that a major safety issue is present and needs fast and efficient attention. Thank you. The consumer stated the fuel pump was severely corroded on the top including two fuel lines that exit the top of the fuel pump. There was a fuel leak resulting from corrosion. The consumer paid for the repairs at his expense. Updated 12/16/10

Have a 2002 Trailblazer that started to smell like fuel. Took to dealer and they said gas tank was cracked where the fuel pump meets tank. Whole vehicle smelled like fuel. Chevy dealer charged me $1,200 for new tank, fuel module and ring. Really dangerous with all the fumes and disappointed in Chevy with no help!!

Gas fumes inside of vehicle, fumes and leaking gas outside of vehicle near gas tank. Took to GM dealer to diagnose and they replaced rusted and leaking fuel pump module at my cost I did ask for and had returned the old part which was rusted. Would this not be considered a safety hazard with leaking gas? it is a blessing that there was not a fire.

Gas vapors coming from under left rear of vehicle when I fill it full of fuel. I saw that this issue is under investigation. I have not yet repaired the vehicle as I am awaiting the outcome of a potential recall. I currently just don't fill it full of fuel.

For several days, I smelled gasoline around my vehicle and had trouble starting the vehicle. Once I got it to a garages, I was informed that the fuel pump assembly was completely rotten and needed to be replaced. The mechanic informed me that he has never seen this before on a modern vehicle. The fuel pump was working, but the components into the pump were rotten and leaking, thus requiring the replacement of the entire fuel pump.

2002 Chevrolet Trailblazer has developed fuel leak from fuel sending unit module. Must have approximately $550 repair done for simple safeties sake. Can't drive around leaking fuel. Unusual for a 5 year old car to develop gas leaks due to manufacturer defect. Would like recall and reimbursement for needed repairs. Thank you.

Refer to NHTSA action number: PE07013 and EA07009.... ODI has received reports that the fuel pump module leaks fuel and or vapor underneath the vehicle. GM states, "the failure mechanism is corrosion of the fuel pump module flange which may lead to a fuel leak. Corrosion of the fuel pump module flange is the result of the vehicle operating in a corrosive environment." ODI has opened this engineering analysis to further assess this issue.

Purchased Feb 1, 2002. Since then have had nothing but problems. Had into 4 different dearlerships fixing many problems but after each visit another problem occurs. From tail lights burning out, windhshield wiper motor failures, instrument cluster replaced, heater control panel replaced once, memory mirror modules replaced 2 times, heated seat switches replaced 2 times, rear window defogger/replaced entire rear window 1 time, battery replaced 1 time ( said battery was at fault for current problems) battery was fine and charged me $ 150 for new battery that was not the correct battery replacement, exhaust gasket became loose/loud and had to be replaced, the fuel pump replaced because it just cut off as I was on the expressway going approx 65 miles an hour, I had to get to the side of the road quickly- had to be towed to dealership. Problem fixed, however after I picked it up then the current problem began. I could go on and on with the problems that I have had. Present problem is that whenever I turn on the heat it dies out with no warning---just stops and stalls. Dealership says they fixd it but upon pick up the problem still exists. Gone to pick it up 2 times, but when I start it and put on heat, it dies all over again even after dealership claims they fixed it. I live in Chicago and it has been a cold winter. Almost caused a crash on another expressway on way home from having the airbag sensor and a complete brake job done and all fluids changed. This vehicle is not worth $ 37,000 and I feel it is time that GM accept some responsibility for this lemon of a vehicle. It is my only vehicle and I am still paying dearly for it but lately cannot even use it as it remains in one dealership after another at my expense. I will not purchase another vehicle from GM. I need help and answers as I am not getting anywhere even with this vehicle still under warranty.

Engine stalled while in heavy rush hour traffic at 55 mph. Pulled to shoulder, attempted to restart engine. Every time we tried to start car, fuel pump engaged and gas sprayed under vehicle...creating a large puddle of fuel.
