The HD Sierra is designed for heavy towing and hauling, and rides stiffer than the Silverado 1500. The standard engine is a 6.0-liter V8. Our tested 397-hp, 6.6-liter turbodiesel produced a whopping 765 foot-pounds of torque and could haul close to a 2,500-pound payload. The diesel is punchy but noisy, and the Allison-made six-speed automatic is smooth.

Owner Reports

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A 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.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A 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.

Model Summary
The HD Sierra is designed for heavy towing and hauling, and rides stiffer than the Silverado 1500. The standard engine is a 6.0-liter V8. Our tested 397-hp, 6.6-liter turbodiesel produced a whopping 765 foot-pounds of torque and could haul close to a 2,500-pound payload. The diesel is punchy but noisy, and the Allison-made six-speed automatic is smooth. Braking and handling capabilities come close to matching the half-ton Sierra. Handling is not agile but has a modicum of responsiveness that other three-quarter-ton trucks don't provide. Reliability of the turbodiesel version is below average.
