2020 GMC Sierra 2500 consumer reviews

Is awesome truck with defined body lines door fit and no wind noise tires not up to quality of truck so swapped them out truck has awesome electronics

this pickup is the ultimate in work vehicles. It will do anything i will need it to do without question. It doesn't smell like diesel which makes my wife VERY happy! I only gave 3 stars for value for money because I believe vehicles are way over priced in general. Walser is very competitive with their prices if not lower.

This is a awesome new GMC 2500 HD fully loaded with every option possible. I have had Ford and Dodge and GMC is like driving a luxury car.

This truck is brand new. It is what I expected it to be. Very spacious cab for a taller man. Plenty of power and great looks.

Great solid truck with diesel. Nice ride with great interior. Debated between half ton and 3/4 ton so glad I went the 3/4 ton route!

Having owns 3 previous model the new Denali hd duramax has excellent new features. The camera system increases safety by a large margin.the rear Ac is a great new feature.

Great new features. Numerous expected upgrades from 2017 model which sucked in technology and rear passenger comfort. Finally caught up with competition. Reliability was great on the 2017. I expect it to be the same on 2020 as well. However, GM company as a whole has worthless customer relations. I purchased my vehicle two weeks before a $750 promotion. They would not give me the promotion. They dump all the responsibility on the dealer so that GM doesn’t look bad. The dealer did a great job and acted very responsibly but GM did not give me the promotion. In this day and age for a company that was rescued by USA tax dollars this type of action is unacceptable. For this reason I do not recommend GM vehicles any longer. I used to be one of their previous mechanics at a very large dealership. They have not learned from their previous mistakes.

The GMC Sierra 2500HD Denali is a great pick up . I only wish it came with Adaptive Cruise control as did my previous GMC Yukon. I Sure miss it

This is what a high performance truck is all about. The style and details of this truck are terrific. I test drove it this year, and I plan on buying one next year. To all you big truck luxury buyers out there, this is a fabulous truck.

After I reviewed the options and performance of the 2020 GMC 2500 Sierra Denali (Diesel), it was a no brainer to upgrade from my Ram which was comparatively close, except for the advanced electronics and HUD, moreover, the safety features are unmatched. The gas mileage is 5 MPG better than my previous Ram 2500.
