The 2015 Chevrolet Silverado 3500 has 7 recalls, the most serious involving a brake pedal pivot nut that can loosen, leaving the driver unable to stop the truck and potentially causing the pedal to interfere with the accelerator.
Two recalls cover the curtain airbags along the roofline: the inflator end cap can break free or the inflator sidewall can rupture, sending the end cap or other pieces into the cabin during a deployment. On the fuel side, trucks equipped with dual tanks have a low fuel sensor in the front tank that can stick, allowing the rear tank to overfill the front tank until pressure builds enough to expand and puncture it against the driveshaft, creating a fuel leak. There is also a concern with the front airbags and seatbelt pretensioners, where a wiring issue can prevent both systems from firing in a crash, leaving the driver and front passenger without full restraint protection.
