Buying a used 2020 GMC Sierra 1500? Check these 12 recalls first
Ten recalls, four rated critical: a fuel pump leak fire risk, a battery cable that can stall the truck, and two separate actions on rear wheels locking up, one specific to diesels. High-severity items add seat belt fire risk, brake caliper bolts that can break, driveshaft separation, an unsecured center seat belt bracket, and two Continental tire recalls. Of 461 unverified NHTSA complaints, engine leads at 229, then power train at 95, with 12 crashes, 13 injuries, and 5 fires.
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.
- Confirm the fuel pump and battery cable recalls were both completed
- Ask which rear wheel lock-up recall applies and whether the remedy was performed
- Check the brake caliper bolt recall and have the tire recalls matched to the installed tires
- Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
