Engine
A damaged fuel line can create a fuel leak, increasing the risk of a fire.
The high pressure fuel pipe that connects to the high pressure fuel pump may become damaged or detached, resulting in a fuel leak. This can occur as a result of the high pressure fuel pump detaching from it's mounting, and would create a fire hazard.
Recall repairs on your Chevrolet, Cadillac, Buick or GMC truck must be performed by a General Motors dealership. General Motors will notify known owners of affected vehicles (a timetable for this notification is not available as of the time of this writing). If you do not receive a notification, but wish to check to see if your vehicle is included, please contact one of your local General Motors dealerships. They will also check for any other incomplete recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with. The General Motors recall number is 18188.
