Before you buy
- Get the 17-character VIN from the seller and run it at nhtsa.gov/recalls. It shows which recalls are still unrepaired on that exact car.
- Verify all applicable hood and tailgate recall repairs.
- Request seat-belt and roof-rail airbag recall completion records.
- Confirm wheel lock-up recall status and ask about transmission or brake symptoms.
- Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
