Exhaust & Emissions
If the front tank overfills, the excess pressure may cause the front tank to expand and contact the driveshaft, possibly resulting in a hole in the tank. The hole will leak fuel, which in the presence of an ignition source, can increase the risk of a fire.
For vehicles equipped with dual fuel tanks, the front fuel tank fuel lever sensor may stick in the low fuel position, allowing the tank to overfill with fuel as fed by the rear fuel tank. If the tank is overfilled, it can expand and possibly puncture on the drive shaft causing a fuel leak and a fire hazard.
Recall repairs on your Chevrolet or GMC truck must be performed by a General Motors dealership. General Motors will notify known owners of affected vehicles beginning in March, 2019. 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 N182204190.
