Buying a used 2021 Chevrolet Silverado 3500? Check these 5 recalls first
The critical brake module fire risk stands apart because it advises parking outside — the hazard is present even with the truck off. A second critical recall covers diesel rear wheels that can lock. Seat belts appear twice, as an unsecured center bracket and as incorrect bolts. Of 40 unverified NHTSA complaints, electrical system leads, followed by powertrain, latches and structure; one crash and one fire were alleged. Routine here: the tailgate unlatch recall.
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 the brake module fire recall is completed and ask whether it was parked outside beforehand.
- Confirm both seat belt recalls, checking bolt type and the center belt bracket.
- Test the tailgate latch and ask about electrical faults, the top complaint area.
- Open recalls are repaired free at any Chevrolet dealer, whoever owns the car — an open recall is a to-do item, not a bill.
