By System
The 2024 GMC Sierra 3500 has 3 recalls, the most serious being a steering gear shaft that can fracture and disconnect from the steering arm, causing a total loss of steering control.
The other two recalls both involve the power-unlatching tailgate, where water can get into the electronic gate-release switch and cause a short circuit that unlatches the tailgate on its own. This can happen while the truck is parked or moving, allowing the tailgate to swing open and drop any unsecured cargo onto the road. These recalls only affect trucks equipped with the power-unlatching tailgate option.
