Buying a used 2020 GMC Sierra 3500? Check these 8 recalls first
A dense recall year: two critical actions on diesels whose rear wheels can suddenly lock, two on hoods that can fly open while driving, plus a seat belt fire risk, an unsecured center seat belt bracket, weak roof airbags and a self-unlatching tailgate. Owners filed 45 unverified NHTSA complaints, and the outcome counts are comparatively high for the volume, with four crashes, two fires and four injuries. Power train is the leading area at 18, then 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 the seller about any lockup or skid incidents
- Inspect the hood latch and confirm both hood recalls were performed
- Ask about the seat belt fire risk and center belt bracket recalls and check the center belt anchorage
- Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
