2018 Chevrolet Silverado

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Silverado.

Body TRUCKTransmission Automatic 8-spd

The 2018 Chevrolet Silverado is a full-size 4WD truck specified with an eight-speed automatic transmission and an engine oil capacity of 6.0 quarts using 5W-30 viscosity, carrying EPA ratings of 18/24/20 mpg. Reliability data records 508 total owner complaints—with powertrain issues cited as the top concern—alongside seven recalls, placing this model year substantially below the 2,168-complaint high water mark of 2000 yet far above the 17-complaint low of 1991 observed across the 1990–2008 historical range. This situates the 2018 Silverado in a moderate position within the model’s documented reliability history, distanced from the severe complaint volumes of the worst years but remaining well above the most reliable vintages.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The federal record provided spans 1990–2008 and does not include data for 2018 or its adjacent model years, so a direct year-over-year comparison for the target year is not possible from this dataset. What the record does show is a clear generational arc: complaints, recalls, and investigations spiked dramatically with the 1999 model year (1,724 complaints, 17 recalls, 14 investigations), peaked around 2000–2003 (over 2,000 complaints in 2000 and 2003), and then steadily declined through 2008 (1,074 complaints, 5 recalls, 3 investigations), suggesting that later years in this generation benefited from progressive manufacturer corrections. The 2018 target year's complaint profile — Power Train (103), Engine (45), Service Brakes (39), and Unknown/Other (31) — indicates powertrain and engine concerns dominate, with 10 crash-related complaints and 4 fire-related complaints flagged, though the data does not specify root causes for any of these. Because the 2018 model falls entirely outside the provided federal record window, there is insufficient trend data here to position it within the generational arc or to assess whether it represents an improvement or regression relative to surrounding years. **Takeaway:** Based solely on this dataset, a confident buy/don't-buy recommendation for the 2018 Silverado cannot be justified — the power train and engine complaint counts warrant a pre-purchase inspection focused on those systems, but you should supplement this with NHTSA data specific to the 2018 model year before deciding.
