2021 GMC Sierra 2500 Recalls & Complaints

The 2021 GMC Sierra 2500 has 6 recalls, the most serious being a brake system fire risk and a transmission defect on diesel-equipped trucks where the rear wheels can lock up without warning, raising the risk of a crash.

Two recalls affect seatbelts in the front-row center seating position: in one case, the bracket anchoring the belt may not be secured to the seat frame, and in another, incorrect bolts may have been used to attach the belt assembly to the vehicle. Either condition can prevent the belt from properly restraining an occupant in a crash. On the tire side, certain trucks equipped with a 17-inch spare tire used alongside 18- or 20-inch road tires can confuse the anti-lock brake system, preventing it from independently controlling the rear wheels during hard braking. There is also a tailgate concern on trucks with power-unlatching tailgates: water can short-circuit the electronic release switch and cause the tailgate to open on its own, potentially dropping cargo onto the road.
