Condition
Some 2004 model year Buick Rainier, 2003-2004 model year Chevrolet SSR, 2002-2004 model year Chevrolet TrailBlazer, Chevrolet TrailBlazer EXT, GMC Envoy, GMC Envoy XL, and Oldsmobile Bravada, and 2004 model year GMC Envoy XUV vehicles contain a fuel tank inlet check valve (ICV) that could fracture. The ICV is located above the full fuel level. A fractured ICV could allow fuel vapors to pass through and droplets of fuel to accumulate on the side of the fuel tank as it passes over the fracture during refueling. If the ICV fractures, the vehicle's Service Engine Soon (SES) light may illuminate, and the owner may notice a fuel odor and/or a few drops of fuel on the ground when refueling the vehicle.
Special Coverage Adjustment
This special coverage covers the condition described above for a period of fifteen years or 150,000 miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
Dealers are to replace the fuel tank. The repairs will be made at no charge to the customer.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after November 2, 2015, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to November 2, 2015, must be submitted to the Service Contract provider.
Vehicles Involved
All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties section in GM Global Warranty Management system. Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.
