Denali HD trim looks like a farm truck.

by cars.com reviewer from Toledo on Tue Nov 24 2020

The Denali HD trim is supposed to be sleek and classy like it was when it first came out in 2010, which I currently own. The 2021 looks like a farm/work truck. I was going to buy the same truck brand new for 2021 but will not be doing so now. Get rid of the rooftop running lights, fender steps, rear bumper steps, mirror lights and novelty tailgate. These features aren't what Denali HD purchasers are looking for or they would buy a lesser trim package. We want sexy, not gimmicky.

Would Not Buy Again!!

by machoman from Casa Casa Grande on Thu Aug 27 2020

Bought this 2011 ext cab. short box 2500 Duramax HD new. I have had continuous maintenance issues since I purchased it. Every sensor or node has been replaced. At 100K a new Turbocharger. At 139K new engine, 2nd turbocharger, injectors, injector pump, starter, radiator, ECM. I have paid out over 44K for repairs. I would not by this product again. Note: I have purchased two used and two new GMC. 2nd Note: I have meticulous about my preventive maintenance needs. No reason for this many issues. Done!! Next truck will be Dodge Cummins.

Smoothest 10-speed transmission in a diesel. EVER

by Richard from Kennesaw, Ga on Fri Nov 13 2020

This truck drives insanely smooth, and when towing it is almost like the trailer is not even there. GM really stepped it up with this truck. Over 15 Camera Views as well...

Best HD truck I’ve ever driven!!!

by GMC Man from Georgia on Fri Nov 13 2020

This truck is in a class of It’s own. Awesome views with the towing cameras. Performance is great on it as well. Gets the job done heavy duty at its finest.
