Envoy 2WD V8-5.3L VIN P (2004)
On some 2004 model year Buick Rainier and GMC Envoy XUV; 2002-2004 model year Chevrolet TrailBlazer, TrailBlazer EXT; GMC Envoy, Envoy
XL; and Oldsmobile Bravada vehicles currently or previously registered in the corrosion areas shown above, the fuel tank modular reservoir assembly,
which contains the fuel pump, may develop corrosion of the fuel feed/return pipes after an extended period of time. Severe corrosion may cause the
formation of small perforations. These perforations may allow a small amount of fuel to accumulate in a recessed area outside of the fuel tank. If this
were to occur, it would be accompanied by a fuel odor. If left uncorrected and the corrosion is allowed to progress, a fuel spray from the pipes may begin
to occur.
Special Coverage Adjustment
This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date
the vehicle was originally placed in service, regardless of ownership.
Dealers are to replace the fuel tank modular reservoir. 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 September 30, 2008, 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 September 30, 2008, must
