2020 GMC Sierra 2500 Recalls & Complaints

The 2020 GMC Sierra 2500 has 9 recalls, the most serious being a transmission control valve that can cause the rear wheels to lock up without warning, raising the risk of a crash.

Two separate recall filings cover this transmission issue, including one where a prior repair attempt did not fully resolve the problem. A related hood latch concern also spans multiple filings: the latch striker wire can fracture and allow the hood to fly open while driving. When front seatbelt pretensioners deploy in a crash, hot gas can vent through the pretensioner bracket and ignite the carpet in vehicles with carpet floor covering, potentially causing a fire inside the cabin.

On the safety equipment side, the roof-rail curtain airbag inflator has a diffuser component that can separate during deployment, reducing the airbag's ability to protect occupants. The front-row center seatbelt bracket may not be secured to the seat frame, meaning the belt may not hold an occupant in a crash. On vehicles equipped with a 17-inch spare tire paired with larger accessory road tires, the mismatched sizes can prevent the anti-lock brakes from controlling the rear wheels independently. Finally, on trucks with power-unlatching tailgates, water intrusion can short the release switch and cause the tailgate to open on its own, dropping cargo onto the road.
