What is wrong: On certain sport utility vehicles, a fuel filter fitting can become disconnected. If this were to occur while attempting to start the engine, a no-start condition would result and fuel would be pumped out the fuel filter onto the ground.
Risk: If the fitting becomes disconnected while the vehicle is in motion, the engine would stop due to inadequate fuel supply and cause a loss of power steering assist. If an ignition source were present, fuel leakage from a disconnected fuel filter fitting could result in a fire.
Remedy: Dealers will replace the fuel filter quick connect retainers. Owner notification began september 20, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1‑800‑222‑1020. Gmc at 1‑800‑462‑8782, or oldsmobile at 1‑800‑442‑6537.

During the course of this ea investigation, odi observed that the majority of the complaints (88%) and warranty claims (94%) were reported for vehicles that are registered for use in the salt belt region of the us.this area includes 20 states in the northeast, mid atlantic and the midwest regions and the district of columbia.consumers in the salt belt region reported to odi that they could smell fuel vapors in their vehicles while driving.upon further examination of their vehicles, they discovered that fuel vapors were coming out of the top of the fuel tank. This condition is caused by corrosion of the return and sender lines of the fuel pump module.water and road salt collect on top of the fuel pump leading to small pinholes appearing on the fuel lines.fuel may leak and collect on top of the module and/or spill onto the ground.the data evaluated under this investigation reflect a relatively low frequency of occurrence that largely arises in salt belt states.gm has extended the warranty on the subject component to ten years or 120,000 miles.further use of agency resources does not appear to be warranted at this time; accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.for additional information select document search.

B lazer hesitates when driving and notice a gas smell when I turn on blazer at the beginning and I noticed a leak inside but was not sure where its coming from. I contacted chevorlet dealer on possible recall they stated its not on there system and I would have to pay for diagnose and because of the mileage maybe they may not be able to fix this. Why would I have to pay for diagnose if its something on their end and its online as a recall on blazers. I think this can be a hazard to be smelling gas that flows in to air system of the blazer while driving.

Hello, our 2002 chevy trailblazer smells inside the car of gasoline. We have to put the windows down in the winter as well as the other season, just to drive the car. My wife gets sick because of the smell. Every time will fill the car or close to empty, the whole car smells with gas fumes. It is very bad and very dangerous. We have tried to get the dealership to fix the problem (in 2017) with the fuel recall, but to no is the answer. This is a serious problem and I don't live in a salt belt region.
