This bulletin has been updated to revise the Part Information section. Please discard all
copies of 14423.
Vehicles involved in Special Coverage 07099 have been transferred to Special Coverage
14423. Special Coverage 07099 has been closed.
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
(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 15 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.

vehicles with a standard wheelbase and the other is for vehicles with an extended wheelbase.
Only one of the two fuel sender kits is required to complete the repair.
SERVICE PROCEDURE
1. Inspect the fuel tank for a leak at the fuel tank inlet check valve (ICV). Refer to Fuel Tank Leak
Test in the Diagnostic Information and Procedures section of SI.
If the fuel tank does NOT require replacement, no further action is required. Inform the
