This page covers 5 recalls, 48 owner complaints and NHTSA crash-test ratings for the 2018 Chevrolet Silverado 2500.
The 2016 to 2018 Chevrolet Silverado 2500 received a four-star overall rating from NHTSA's New Car Assessment Program for US-market vehicles. The truck earned four stars in frontal crash protection and five stars in both side crash and side pole crash tests. Rollover resistance received three stars. NHTSA applies these ratings across model years until a significant redesign occurs, so this assessment covers the entire 2016 to 2018 range.
4/5 Overall
NHTSA 5-Star Safety Rating
For the 2018 Silverado 2500, engine and electrical complaints make up the bulk of what owners report. On the engine side, multiple owners describe fuel pump failures, specifically the low-pressure pump, leading to stalling, sometimes in traffic, and costly repairs. Electrical complaints cover a range of issues, including a recurring pattern of rear defroster short circuits that owners say caused the rear window to crack or shatter without any warning light. A handful of odometer fraud reports also appear in the complaint set, with private-sale buyers discovering significant mileage discrepancies, in some cases, the actual mileage running more than double what was shown at purchase. Powertrain complaints are fewer in number, rounding out the picture at a lower volume. The rear defroster and window damage pattern and the fuel pump stalling complaints are the most consistently described mechanical issues across this model year.

By System
The 2018 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.
Crew Cab models face a separate safety concern with the roof-rail curtain airbags: the inflator's end cap can detach or the inflator itself can rupture, sending the cap or other fragments into the cabin during deployment. On the fuel side, trucks equipped with the optional dual fuel tank can experience the rear tank collapsing under pressure, which cuts off fuel transfer to the front tank and causes the engine to stall unexpectedly while driving. The front seatbelt retractors on certain trucks were built with an incorrect internal torsion bar, meaning the belt may not manage the load properly in a crash and could allow more forward movement than intended, raising the risk of injury.
