NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2015 Chevrolet Silverado 3500:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.

The brake pedal pivot bolt nut loosened itself and came off of the bolt, allowing the bolt to back out of the pedal mount and the brake pedal fell out of position and became lodged behind the accelerator pedal. Thankfully no accident occurred. After performing research with local dealer and independent repair shop it was found to be an obvious repeat failure of the General Motors safety recall #20760E already performed on the vehicle. I reached out to GM customer support who were rude and I received no help in the matter. Can provide more information upon request.
