What Owners are Saying About the 2020 GMC Sierra 2500 HD Regular Cab

"Headache from the start"

"Infotainment system is unreliable and does something different every time I start the truck. I have been back to the dealer 6 times for repairs to the parking sensors. Two weeks ago the DEF tank heater shorted out and the dealer cant get parts. I can get the part if I want to pay 750.00 for something covered under warranty but GM won't release them to the dealer for warranty work. When passing a car on a hill the wheels spun a bit which caused the traction control and hill start assist to come on at the same time. Left drivers mirror won't fold in like the right one does. Radio tells me it needs an update but fails when it try's to download it. All for this and 72000.00 price tag. I can't wait to get rid of it."

"My Forever Truck"

"I bought this as my retirement vehicle. Couldn’t ask for a better truck. Lots of power, reliable, and plenty of room are some of the traits I love the most. I haven’t had to do anything except for routine oil changes/maintenance and topping off the DEF every 3rd fill up of diesel. Getting about 23 mpg which is great for such a BEAST of a truck."

"Fantastic Truck"

"Solid and dependable, I still love this truck! Absolutely zero issues. Whether it's load after a home improvement run, pulling the camper into the mountains or across the country, or shifted into 4-wheeldrive...it does its job with excellence."
