Best truck I’ve bought

by Hammer from Butler, pa | March 26, 2021

The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

I absolutely LOVE my truck!

by Kasi from South Mississippi | January 04, 2021

We bought this truck in July of 2020 and it is my “Mama-mobile”! Yes it’s a woman’s truck 😉 I have a 7 1/2 year old son and almost 5 year old son, both who are extremely tall for their ages and there is PLENTY of room in the back with room to spare!!! I have put 15k miles on it already and it’s still drives so smooth and I have not had a lick of trouble out of it!! No regrets on this purchase at all, and I’m usually very critical of vehicles!

Pretty Bummed Out

by MattRealEstate from Baltimore, MD | December 13, 2020

Hopefully all will get resolved...coming out of a Tahoe with 110,000 miles and excited to get into my 2020 Sierra Denali 1500 Carbon Pro with the Duramax Diesel. At this point, I have had the car 2 weeks and it has been back at the deal twice, this time going on 4 days. First issue was a coolant sensor that set off an engine warning and the second problem is car wouldn’t start due to dead battery. Apparently 4 open recalls on the 2020 and I guess my dealer didn’t take care of them? They still can’t figure out what is draining the battery. Truck has about 900 miles on it. Now have the feeling of “what’s going to be messed up?” Every time I press the start button. Certainly takes the enjoyment out of owning this physically beautiful truck. When it works it is an absolute joy to drive and it is the best looking truck on the road....all that said....I want it gone.
