2012 GMC Sierra 1500 Hybrid recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Electrical system
What's wrong, in plain English: Wiring, modules, batteries. Short circuits can cause stalls or fires. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.
What could happen: If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.
The fix: GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The recall began on February 12, 2015. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14696…
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2012 SIERRA 1500 HYBRID.
- Book a repair at any authorized GMC dealer. Quote NHTSA campaign 14V827000 (manufacturer code 14696 for the original equipment, and 14912 for the service replacement parts).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-458-8006.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
