The HD Sierra and its twin the Chevrolet Silverado HD are designed for heavy towing and hauling. The 6.0-liter V8 and 6.6-liter turbodiesel, both mated to a six-speed automatic, carried over on the 2015 redesign. There is also a natural gas (CNG) version of the 6.0-liter V8. GM said that the new cabs and interiors provide increased space and comfort, with extensive storage space.

    Overall Owner Satisfaction

    Consumer Reports’ Annual Owner Satisfaction Survey can improve the chances of finding a compatible car match. How? Our survey data reveals whether, all things considered, owners would buy the same car again. The answer to that question is what determines our owner-satisfaction rating, which is a powerful piece of intel because it predicts how well a particular model will satisfy other owners.

    Comfort

    Includes seats, climate control, noise, and ride

    What Owners Say

    "We use this truck to travel with our fifth wheel. We get a lot of seat time so comfort is very important. The truck is very quiet for a diesel. The seats are good for all day trips. The ride is not so great but it is, after all, a one ton truck with dual rear wheels."

    Jimmy T., OK (2015 GMC Sierra 3500HD)

    "Very comfortable quality seating, front & rear. For a diesel engine, very little engine noise and road noise."

    John B., PA (2015 GMC Sierra 3500HD)

    "Very comfortable seats with many adjustments for personal comfort. Much quieter than our previous Chev truck."

    Barbara D., AB (2015 GMC Sierra 3500HD)

    "Bucket seats are very comfortable. Very quiet ride. Very little road or wind noise."

    Anonymous, WA (2015 GMC Sierra 3500HD)

    "Extremely quiet interior, especially for a diesel. Excellent seats and climate control. Very nice fit and finish of interior overall."

    John H., MD (2015 GMC Sierra 3500HD)

    "Not well padded and not comfortable."

    Anonymous, TN (2015 GMC Sierra 3500HD)

    Value

    Did you get what you wanted relative to the price you paid?

    What Owners Say

    "when i bought the truck I wanted a certain rim on it, they provided that request, now after 2 1/2 years the wheel s are corroding. I am not impressed with the response from GM, they said that it is normal wear and tear. when you buy a truck worth 62,000 dollars you expect more."

    Percentage of owners who would definitely purchase that same vehicle again. Owner-satisfaction Ratings are determined by the percentage of those who answered "definitely yes" to the question asked by the Consumer Reports Annual Auto Survey "Considering all factors (price, performance, reliability, comfort, enjoyment, etc.), would you get this car if you had to do it all over again?". If we don’t have sufficient data, a similar model might be used to form the owner-satisfaction score.
