Transmission trash
By Jason on Monday, April 07, 2025
Bought a 2023 GMC Duramax diesel Sierra SLT had it for two years hit 50,000 miles. The throttlebody broke went in for service. Got it back three weeks at 62,000 miles now my transmission is slipping. I travel back-and-forth from South Carolina to North Carolina for work daughter’s truck would be my forever truck. What a joke Hundred thousand dollar truck junk - 5.0
Fantastic truck
By Jjj on Sunday, November 07, 2021
This one of the most solid vehicles that I have ever driven! The 401 hp engine is more than enough power and the transmission is smooth! Highly recommend this truck! - 3.0
Don't judge a truck by the appearance
By jmil on Wednesday, May 11, 2022
Great truck, loved it until the DEF tank heater malfunctioned and shut down the truck. Now sitting waiting for the replacement tank for over 10 weeks. Turns out every HD truck 2020 and 2021 has the same problem and all will need this replacement that is being produced at a snail's pace by GM. Per the dealership, last count, over 9000 trucks like mine are idle waiting for this part. $65000 waste of money and terrible service by GMC (not the local dealership).
