Before you buy

1. 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.
2. Verify applicable block heater cord recall repairs and inspect the cord's condition.
3. Obtain completion records for seat belt retractor and side airbag recalls.
4. Ask about stalling and request rear fuel tank recall and repair documentation.
5. Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
