Under the hood, a 2.0L turbocharged engine paired with a 9-speed automatic transmission and all-wheel drive delivers 21 miles per gallon in the city and 26 on the highway, balancing power with efficient operation. The turbocharged design provides responsive acceleration when you need it while maintaining reasonable fuel economy for daily driving and longer trips.
The Denali trim elevates the ownership experience with thoughtful details. Perforated leather-appointed seating creates an inviting cabin, while heated front seats and steering wheel provide comfort during colder months. The power sunroof floods the interior with natural light, and the power sunscreen allows you to control glare and heat as conditions change.
Technology integrates seamlessly into your routine. The GMC infotainment system with navigation keeps you on course, while Apple CarPlay and Android Auto connectivity bring your smartphone's functionality to the dashboard. SiriusXM satellite radio expands your entertainment options beyond traditional broadcasts, and the Bose sound system ensures quality audio throughout the cabin.
Safety and convenience work together throughout this vehicle. Four-wheel independent suspension and speed-sensing steering provide confident handling, while electronic stability control and traction control manage power delivery. A rearview parking camera assists with backing maneuvers, and OnStar emergency communication provides an added layer of security. Dual front and side airbags, along with ABS brakes and brake assist, support your protection on the road.
This local trade presents an opportunity to own a well-equipped Denali with established service history and familiar maintenance records. The combination of practical capability, premium comfort features, and proven reliability makes this a solid choice for buyers seeking a capable midsize SUV.

Excellent
By Estiva | on 7/28/2026 5:46:15 PM
2023 Terrain SLT AWD with 96,000 miles. I’ve had since new, and maintained exclusively at my local Chevrolet/GMC dealer. Most of my miles are highway, but I’m averaging 32 MPG, and have had NO issues. I had the tires replaced at 80,000, it still has the original brake pads. This vehicle still drives like new. I was recently at a family reunion and received compliments on the vehicle. The only thing I miss is the power liftgate I had on my 2019 Chevrolet Equinox.… - 5.0
Awesome car
By OHGMCDenali | on 2/13/2026 7:18:25 PM
This purchase has turned out to be the best thing I did in car purchasing in a while. I enjoy the ride, the comfort and the equipment. Its not a rocket ship but who needs an SUV to go from 0 - 60 in 2 secs? If you need that stay in a sports car. You'll love this well made SUV… - 4.0
