The 2022 GMC Sierra 2500 has 3 recalls, the most serious being a brake system defect where water can enter the brake pressure modulator and cause an electrical short that may lead to a fire, and a diesel-engine transmission issue where the control valve can fail and cause the rear wheels to lock up without warning.
On the tailgate side, this recall only affects trucks equipped with the power-unlatching tailgate: a water-damaged electronic release switch can trigger the tailgate to unlatch on its own while the truck is parked or moving, dropping the gate unexpectedly and sending any unsecured cargo into traffic.
