4/5 Overall
NHTSA 5-Star Safety Rating
Electrical system and engine complaints dominate what owners of the 2017 Silverado 2500 report. The most consistently described issue involves the fuel pump control module failing, causing the engine to shut off unexpectedly or the truck to crank without starting, multiple owners report this happening more than once on the same vehicle, and several note the part has been difficult or impossible to source. Powertrain complaints largely track with this pattern, often describing lost power while driving. Electrical complaints span a broader range, but steering-related failures come up more than once: owners describe the power steering cutting out and the wheel going stiff, as well as a separate pattern of excessive slack or looseness in the steering. A handful of reports mention airbag deployment with no collision involved, specifically the side curtain airbags activating while the steering wheel and dash airbags did not.

By System
The 2017 Chevrolet Silverado 2500 has 5 recalls, the most serious being a fire risk tied to the optional engine block heater on Duramax 6.6-liter diesel models, where a short circuit in the heater cable or its terminals can ignite a fire.
On the fuel side, trucks equipped with the optional dual tank setup have a rear fuel tank that can collapse inward, cutting off the fuel pump's ability to transfer fuel to the front tank and causing the engine to stall without warning while driving. Two seatbelt recalls cover different parts of the restraint system: the front seatbelt retractors were built with the wrong torsion bar, meaning the belt may not pay out or lock correctly in a crash, and a separate issue affects the front seatbelt pretensioners, which are the devices that snap the belt tight against an occupant when a collision occurs. If the pretensioners fail to fire, or if the front airbags don't deploy when they should, the driver and front passenger absorb significantly more crash energy than the restraint system was designed to allow.
