Buying a used 2021 GMC Sierra 2500? Check these 6 recalls first
The 2021 GMC Sierra 2500 has 6 recalls in this group. The brake module fire recall carries a park-outside instruction, making its applicability and completion especially important. Other entries concern seat belt brackets and bolts, spare tire interference with ABS, tailgate unlatching, and diesel rear wheel lockup. Its 51 NHTSA owner complaints are unverified reports: POWER TRAIN 12, EXTERIOR LIGHTING 9, ENGINE 8, and SERVICE BRAKES 6. The record includes 1 reported fire.
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 brake module fire recall status and follow applicable park-outside instructions.
- Obtain seat belt bracket, bolt, and tailgate recall completion records.
- Confirm spare tire ABS and applicable diesel wheel lockup remedies; review brake and powertrain records.
- Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
