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 VIN applicability and completion of engine failure and wheel lockup recalls.
- Obtain records for seat belt bracket, seat belt bolt, and tire remedies.
- Confirm spare tire ABS recall work and request engine and transmission repair history.
- Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
