      Safety and Security

      • Forward collision mitigation - Forward thinking. You look away for just a second and suddenly the vehicle in front of you has stopped. That's when the forward collision mitigation system comes to life. When it senses an impending impact, it will activate a combination of features to help prevent or reduce the severity of an accident. Forward collision mitigation is always looking ahead.
      • Rear camera - Watching your back! The rear camera helps you see obstacles and hazards you otherwise couldn't by showing enhanced images of what is behind you. The rear camera is an extra set of eyes that's both convenient and safe.
      • Head-up display - Keep your head up! You don't have to take your eyes off of the road to get information from your dashboard anymore. With head-up display, important driving information - like speed and RPM's - displays on your windshield in your line of sight. Because when you're driving, the most important information lies on the road ahead. Keep your eyes on the road with head-up display.

      Technology and Telematics

      • Smart device mirroring - Smartphone, meet smart car. You can control your device through your vehicle's infotainment system. Smart device mirroring brings together safety and convenience by making it easier to find what you're looking for while keeping your eyes on the road.
      • Mobile hotspot - WiFi on the fly. Connect your devices to the Internet through your vehicle's private mobile hotspot and take the internet wherever your journey takes you, without eating up your data allowance. Find the hotspot with mobile hotspot.

        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

        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.

        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!
