Buying a used 2021 GMC Sierra 1500? Check these 7 recalls first
Seven recalls, two critical: rear wheels that can suddenly lock up, plus a diesel-specific version of the same issue. High-severity items include 6.2L V8 engines that may fail, wrong seat belt bolts, an unsecured center seat belt bracket, and faulty Continental tires; a mismatched spare tire recall is medium. Engine dominates the unverified complaint record, 299 of 561 reports to NHTSA, followed by power train at 134. Six fires, 5 crashes, and 2 injuries are reported among them.
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.
- If it has the 6.2L V8, confirm the engine failure recall inspection or remedy was done
- Verify both rear wheel lock-up recalls, including the diesel-specific one if applicable
- Check the seat belt bolt and bracket recalls, plus whether the spare matches
- Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
