## NHTSA's summary

The Fuel Injector Condition\-Specific Repair Coverage Program applies to qualifying repairs for the required replacement of one or more the fuel injectors which were determined to have failed due to a buildup of external corrosion in the engine’s center fuel injector bore area that resulted after this location was periodically contaminated by engine coolant residue over time. This special program’s coverage is 15 years / 150,000 miles as determined from the vehicle's original in\-service / first delivery date.
