2015 GMC SIERRA Recalls — Canada & USA

The 2015 GMC Sierra has 11 recalls, the most serious being a rear axle shaft that can fracture without warning, causing a rear wheel to separate from the vehicle while driving. Several recalls involve fire risk. On models with 4.3L or 5.3L engines, exhaust components can overheat at idle in cold temperatures, melting nearby plastic parts and potentially starting an engine fire. On diesel HD models with dual fuel tanks, loose fuel transfer pump fittings can allow diesel to leak, and a separate recall covers a poorly secured fuel tank vent line that can detach and also cause a fuel leak near an ignition source. The ignition system on certain trucks can snap back from the Start position to Accessory unexpectedly, cutting engine power along with power steering and braking while the vehicle is moving. On HD models, power steering hose clamps may not be properly secured, allowing the hose to pull free from the pump or steering gear and dump steering fluid. There is also a separate recall where the electric power steering assist can drop out suddenly while driving, though a dashboard message and chime do warn the driver. On the safety equipment side, side curtain airbag inflators on certain trucks can fail during a crash, and a metal end cap from the inflator can be launched into the cabin and strike an occupant.
