Buying a used 2020 GMC Sierra 2500? Check these 9 recalls first
This is the heaviest recall year in the range: two critical actions on diesels whose rear wheels can suddenly lock, plus hoods that can fly open while driving, a seat belt fire risk, an unsecured center seat belt bracket, weak roof airbags, a spare tire that can disable anti-lock brakes, and a self-unlatching tailgate. Owners filed 74 unverified NHTSA complaints, with one crash, three fires and one injury; power train reports dominate at 22, followed by electrical and brakes.
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 both rear-wheel-lock recalls on the diesel and ask about any hard braking or lockup episodes
- Check the hood latch and secondary latch and confirm the hood recall repair
- Ask whether the seat belt fire risk and center belt bracket recalls were completed, and tug-test the center belt
- Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
