The 2015 GMC Sierra HD has 3 recalls, including a side curtain airbag inflator defect where a metal end cap or other fragments can break loose and strike occupants inside the cabin.
The other two recalls both involve the brake pedal pivot nut, and together they reflect a situation where an earlier repair attempt did not fully resolve the issue. A loose pivot nut can cause the brake pedal to become sloppy or stop working entirely, which can prevent the driver from slowing the vehicle or cause the pedal to interfere with the accelerator.
