2018 GMC Sierra 2500 Recalls & Complaints

The 2018 GMC Sierra 2500 has 5 recalls, the most serious being a fire risk tied to the optional engine-block heater, where an electrical short in the heater cable or its terminals can ignite a fire.

Trucks equipped with the optional dual fuel tank have a separate concern: the rear tank can collapse and cut off fuel transfer to the front tank, causing the engine to stall without warning. On the occupant safety side, the roof-rail curtain airbag inflator can rupture or shed its end cap during deployment, sending metal fragments into the cabin. Front seatbelt retractors on some trucks were built with the wrong internal torsion bar, which can cause the belt to perform below the required standard in a crash and raise the risk of injury. Some of these recalls only affect trucks with specific options, including the dual-tank setup, the Duramax 6.6-liter diesel, or the optional block heater cord.
