This page covers 6 recalls and 13 owner complaints for the 2017 Chevrolet Silverado 3500.
Complaints for the 2017 Silverado 3500 are spread across a few systems with no single dominant pattern, given the thin complaint volume. In the powertrain area, owners describe transmission trouble including failure to upshift and a stuck torque converter, with the check engine light coming on and a diagnostic code pointing to the torque converter clutch circuit. An isolated but notable electrical complaint describes a melted fuse panel and main wiring harness failure that left the truck unable to start even after battery and starter replacement. One owner reports the touchscreen malfunctioning intermittently at low mileage, with dealers unable to resolve it after multiple reprogramming attempts. A separate report describes the automatic emergency braking system triggering unexpectedly on freeway on-ramps, cutting throttle and sounding alerts when other vehicles pass perpendicularly ahead.

By System
The 2017 Chevrolet Silverado 3500 has 6 recalls, the most serious involving the fuel system on trucks with dual tanks, where a stuck fuel sensor or a collapsing rear tank can cause overfilling, a punctured tank, or an engine stall.
On gasoline-engine models with dual tanks, a stuck fuel-level sensor in the front tank can allow the rear tank to keep pumping fuel until the front tank expands and contacts the driveshaft, potentially punching a hole in the tank. On diesel dual-tank models, the rear tank can collapse and cut off fuel transfer, stalling the engine while driving. There are also two related fire risks on trucks with the optional Duramax 6.6-liter diesel engine and an engine block heater: the heater cable or its connection terminals can develop an electrical short that may start a fire. On the safety equipment side, the front seatbelt retractors were built with the wrong torsion bar and may not hold properly in a crash. There is also a concern with the front airbags and seatbelt pretensioners, which may fail to deploy in a crash, reducing protection for the driver and front passenger.
