2023 GMC Sierra 3500

The defect

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.

The risk

An unlatched tailgate may open while driving and result in a loss of unsecured cargo, creating a road hazard and increasing the risk of a crash.

The 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. Owner notification letters were mailed May 17, 2024. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N232426400.

The vehicle experienced a catastrophic fuel system failure involving the high-pressure fuel pump and related fuel system components. While driving, the engine began stalling and lost power, making the vehicle unsafe to operate. The failed components were replaced during repairs; however, the repair records, photographs, and additional documentation are available for inspection upon request. The failure created a significant safety risk because the vehicle stalled unexpectedly while being driven, resulting in a sudden loss of power. This placed the occupants and surrounding motorists at risk by reducing the driver's ability to safely control the vehicle or move it out of traffic. The problem …

275/65R20 - Goodyear Wrangler. This is the tire that came with the vehicle. It had approximately 32,000 miles. The tire separated and exploded. We installed the spare but one of the other tires is getting ready to explode. This is not normal wear and tear. This is out of the ordinary that tires on a new vehicle explode. We were on [XXX] when this happened. This tire is a death trap. This is forcing us to replace all 4 tires because we do not know what is going to happen. The dealership (Jerry Seiner) will do NOTHING. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
