The hood-latch striker wires on replacement hoods installed for Safety Recall 20V-142 may not have been heat-treated properly, possibly causing them to fracture.
Consequence: If a striker wire fractures, the hood may open unexpectedly while driving, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will replace the hood assembly, free of charge. For hoods sold over the counter, dealers will contact customers with instructions for hood replacement.

The diffuser component of the Roof-Rail Air Bag (RRAB) inflator may not have been properly crimped to the inflator and could separate from the inflator during air bag deployment.

General Motors, LLC (GM) is recalling certain 2020-2024 Chevrolet Silverado 2500, 3500, GMC Sierra 2500 and 3500 vehicles equipped with power-unlatching tailgates. The tailgate's electronic gate-release switch may short circuit due to water intrusion, which can result in the tailgate inadvertently unlatching while the vehicle is in park.

Remedy: Owners are advised to check that the tailgate is closed and latched before driving. Dealers will replace the exterior touchpad switch assemblies, free of charge.
