2020 GMC SIERRA 3500 Recalls — Canada & USA

The 2020 GMC Sierra 3500 has two recalls, the more serious being a transmission control valve failure that can cause the rear wheels to lock up suddenly, raising the risk of a crash. The second recall affects trucks equipped with power-unlatching tailgates: water can get into the electronic gate-release switch and cause a short circuit, which may trigger the tailgate to unlatch on its own. If this happens while driving, cargo in the bed can fall onto the road. Note that the transmission issue stems from a prior repair that was not completed correctly, so owners who had that earlier work done should confirm whether this recall also applies to their vehicle.
