Models
Supercede:
The ending breakpoints for the 2002 Chevrolet TrailBlazer and the 2003 Chevrolet TrailBlazer EXT have been revised. Please discard all copies of bulletin 07076, issued September 2008.
Condition
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.
