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… - 3.0
Infotainment system unreliable!
By Brian C | on Friday, June 27, 2025
The servicing dealer has been great, the GM engineers not so much! The truck will without warning have no sound for the radio and the blinkers. GM told the dealership to reprogram then when that didn't work they said replace the amplifier and when that didn't work, they said replace a module, and when that didn't work they said to replace the amplifier again, and when that didn't work they said we know it's a known problem but we don't know how to fix it. All of this with less than 9k miles. The dealer has done everything that GM has asked them to do, but none of it works. It's very frustrating to pay this much for a truck and you can't get the radio to stay working. It also got away from the factory with paint damage and a dent in the hood,( the dent is from the inside out on a double wall). I thought I was upgrading when I went from a F250 Lariat to a Denali, but I may have traded one headache for another.… - 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!…
