These trucks are much stiffer and ride less comfortably than the standard 1500 (1/2 ton). They are designed for hard work and a 3/4 ton capacity. The ride is bouncy but the available engines include a relatively refined, Isuzu-developed 6.6-liter turbodiesl V8 and a huge 8.1-liter, 340-hp V8.

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.

Overall Owner Satisfaction

Owner Satisfaction with:

Driving Experience

Includes acceleration and handling

What Owners Say

"I pull a 30 ft. 5th wheel trailer. Pulls and accelerates much, much better than the '93 Dodge I had previously."

James B., CA (2004 GMC Sierra 2500HD)

"Quick acceleration and smooth shifting with the Duramax engine and Allison transmission."

Anonymous, AL (2004 GMC Sierra 2500HD)

"This truck will pass everything except a gas station. More power than it needs, so be careful on slick pavement."

Stuart W., CA (2004 GMC Sierra 2500HD)

"I pull a 39ft 5th Wheel RV, 15,600 lbs. across country. This truck never hesitates, over 200,000 miles!"

RANDY P., TX (2004 GMC Sierra 2500HD)

"I bought this vehicle for the purpose of towing a heavy boat and an equally heavy travel trailer. Does both with ease. Does handle like a heavy pickup, but I am not disappointed in that at all."

STEPHEN J., CA (2004 GMC Sierra 2500HD)

"I only use this vehicle for towing trailers (thus I don't know what my MPG is empty). Very happy I chose a diesel engine over gas, but what impresses me most, is the Allison transmission in it."

DALE T., OR (2004 GMC Sierra 2500HD)

"had the steering shaft replaced, due to a known issue with a clunking when turning the steering wheel. The steering gear box needs to be replaced, but have not found anyone that makes one including the manufacturer (still looking)."

JAMES B., FL (2004 GMC Sierra 2500HD)

"Pulls very heavy loads with no problem"

Brad H., TX (2004 GMC Sierra 2500HD)

"The combination Diesel engine and Allison transmission are an excellent pair for towing."

Dale T., OR (2004 GMC Sierra 2500HD)

"Pulls my enclosed trailer with ease."

Anonymous, IL (2004 GMC Sierra 2500HD)

"It meets my needs in every area. Strong towing, fair in mpg, stylish as any pu and comfortable"

Kenneth K., MA (2004 GMC Sierra 2500HD)

Comfort

Includes seats, climate control, noise, and ride

What Owners Say

"I have been told that riding in my pickup is almost like riding in a Cadillac, and I agree."

Anonymous, VA (2004 GMC Sierra 2500HD)

"Seats have worn out due to use. Suspension in seat is not comfortable"

Michael D., SC (2004 GMC Sierra 2500HD)

"When you buy a heavy duty truck you expect it to be just that. This truck rides like a tank if there is no weight (materials) on it."

Anonymous, CA (2004 GMC Sierra 2500HD)

"Driver seat very comfortable."

Anonymous, AZ (2004 GMC Sierra 2500HD)

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.
