2020 GMC Sierra 3500 Denali review

Great Diesel truck when emission sensors work

January 30, 2023
By Mahrad from Lady Lake, FL
Owns this car

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

2018 GMC Sierra 3500 Denali review

An overall nice truck but for a person at my size(5,11)

November 8, 2024
By Magga from Ölfus,Iceland
Owns this car

An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!
