2011 Chevrolet Silverado 2500HD Reliability - Consumer Reports
We found this version of the Silverado 2500 to be the best choice of the three heavy-duty trucks available on the market during this period. Payload and towing capacity are impressive, yet braking and handling capabilities come close to matching those of the half-ton version of the truck, a combination of performance attributes its rivals couldn't match.

Reliability

We expect the 2022 Silverado 2500HD will be more reliable than the average new car. This prediction is based on data from 2020 and 2021 models. Select the used car model year to see reported issues with those similar past models.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for over 300,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2021 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.
