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.

Vehicle listed caught on fire while driving on interstate with unknown cause. No previous warnings. Was a risk to safety of driver/and or passengers.

My vehicle has developed a leak in the plastic fuel tank at the junction of the fill hose connection and the body of the tank that is causing release of flammable vapors and liquid gasoline underneath the vehicle and causing failure of emissions systems. These vehicles have a rampant and long-standing reputation for developing leaks in their plastic fuel tanks at this location which cannot be repaired by any normal means available to a consumer. Virtually all of these vehicles eventually develop leaks, which cause release of flammable fuel vapors and raw gasolene releases. Why isn't there a recall on these faulty fuel tanks? The manufacturer only provided a short-term solution for a limited period of time that is no longer available for vehicles that still have the leaking tanks. The condition is dangerous.

Strong gasoline odor. Received a notice in 2016 regarding this. Notice said no action required if there was not gasoline smell. The odor was noticed about a month ago. Called the dealer that sent the notice who told me it expired! They never said the repair would expire, but to ignore it unless I smelled gasoline. So now gasoline fumes are not dangerous??
