5 safety recalls, most serious first
1. Seat belts
What's wrong, in plain English: Seat belts may not hold you in a crash. The front seat belt retractor assemblies were built with the incorrect torsion bar. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 209, "Seat Belt Assemblies."
What could happen: The seat belt retractors may not perform as intended during a crash, increasing the risk of injury.
The fix: GM will notify owners, and dealers will replace both front seat belt retractor assemblies, free of charge. The recall began March 24, 2021. Owners may contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020. GM's numbers for this recall are 17368, 17375, and 17376.
What to do

- Book a repair at any authorized GMC dealer. Quote NHTSA campaign 17V567000 (manufacturer code 17368, 17375, and 17376).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-888-988-7267.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
