GM Recalls Over 320,000 Heavy-Duty Trucks for Tailgate Malfunction

General Motors (GM) recently announced a recall impacting over 320,000 heavy-duty Chevrolet Silverado and GMC Sierra pickups due to a defect in the power-unlatching tailgate system. The issue, which affects vehicles from the 2020–2024 model years, can result in unexpected tailgate openings, raising concerns about safety and potential property damage. The recall, initiated in February 2024, involves trucks sold in both the United States and Canada.

Affected Vehicles and Key Models

The recall targets the following heavy-duty models:

• Chevrolet Silverado 2500/3500 (2020–2024)
• GMC Sierra 2500/3500 (2020–2024)

These vehicles come equipped with an electronic tailgate release switch, which, under specific conditions, may short-circuit due to water infiltration. This malfunction can cause the tailgate to open while the truck is parked, creating risks for unsecured cargo.

Timeline of Events

1. Initial Investigation: GM began its inquiry in November 2023, prompted by consumer complaints of unexpected tailgate openings.
2. Defect Identification: By January 2024, GM engineers identified that water intrusion into the external tailgate release switch caused short circuits, leading to the malfunction.
3. Recall Announcement: GM officially announced the recall in February 2024.
4. Customer Notifications: Recall notifications were scheduled to begin on March 18, 2024.

Nature of the Defect and Associated Risks

Identified Issue

• Water can enter the external tailgate switch, causing a short circuit that triggers the tailgate to unlatch unexpectedly.

Safety Risks

• Documented Incidents: GM received 136 reports of malfunctioning tailgates, including three minor property damage cases and one minor injury.
