Fuel pump module leaks gasoline
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.

What 2003 GMC Envoy 360 owners say
Most recent owner complaints, unedited.
While traveling 55 miles per hour on icy roads my vehicle lost control and hit a guard rail, then a telephone phone which was knocked over causing it to roll 3 times. The vehicle is a total loss. During the accident none of the airbags were deployed. As traumatic as the accident was I feel they should of went off.
Fuel pump module corrosion causing leaking fuel and fuel vapors from the top of the fuel tank. This is due to a design defect as the fuel pump module sits lower than the highest point of the fuel tank and moisture and debris accumulate on top of the fuel pump module. The top of the module is not manufactured with appropriate rust-proofing measures and the materials used leave it prone to rusting and failure, compromising the seal and allowing fuel to escape from the tank. This poses a fire hazard, especially if fuel is able to reach heated exhaust pipes, etc. I took my vehicle into a a gmc dealership and was denied repair of the vehicle or reimbursement for repair. There was a special coverage for this vehicle that has since expired, proving that gm is / was aware of the problem. Given the numerous complaints of this exact same issue, this should be escalated to recall status due to the inherent safety issue and fire risk.
