- Book a repair at any authorized GMC dealer. Quote NHTSA campaign 03V094000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-745-6096.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
