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 completion of applicable fuel-tank recalls and ask about stalling.
- Request block-heater cord recall repair records.
- Confirm seat-belt and airbag recall repairs and ask about brake or steering 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.
