    • Transmission trash

      By Jason on Monday, April 07, 2025

      2.0
      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
    • Fantastic truck

      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!
    • Don't judge a truck by the appearance

      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).
    Price is plus tax, tag, title, registration, any dealer-installed accessories, dealer fee of $989 and Electronic Registration Filing Fee of $299, which charges represent costs and profits to the dealer for items such as inspecting, cleaning, and adjusting vehicles and preparing documents related to the sale.

All advertised pricing is on in-stock units only and is inclusive of all applicable manufacturer offers and may not be combined with other exclusive offers. All payment quotes received assumes that taxes and fees will be paid at the time of sale by the customer in addition to the down payment amount stated or shown. Certain offers presume financing through the Manufacturer Captive Lender, subject to approved credit.
