2021 GMC YUKON

If you're searching for a 2021 GMC Yukon SLT for sale in Detroit, Michigan, your search ends here. Best of Michigan Auto Sales has this commanding full-size SUV in stock and ready for a test drive. With 65,682 miles on the odometer, this Yukon SLT hits the sweet spot for used SUV shoppers — enough life already lived to keep the price competitive, but plenty of road ahead for your family and adventures alike.

About This 2021 GMC Yukon SLT

The 2021 model year was a landmark for the Yukon. GMC completely redesigned the Yukon from the ground up, delivering a longer wheelbase, an available independent rear suspension, and a significantly more upscale interior. The SLT trim sits comfortably in the middle of the Yukon lineup — above the base SLE but below the ultra-luxury Denali — giving buyers a premium experience without stretching into top-tier pricing territory. At just over 65,000 miles, this Yukon is well within its prime years of service, especially given the durability that GMC full-size SUVs are known for.

This is a 4WD-equipped model, making it exceptionally well-suited for Michigan drivers who deal with lake-effect snow, icy city streets, and unpredictable winters throughout Wayne County and the greater Detroit metro area.

2021 GMC Yukon Performance and Engine

Under the hood of this Yukon SLT sits GMC's proven 5.3-liter EcoTec3 V8 engine — a powerplant with an outstanding reputation for balance between muscle and efficiency. Paired with a smooth-shifting 10-speed automatic transmission with overdrive, this drivetrain delivers confident acceleration whether you're merging onto I-75 or hauling a trailer up north to the lake.

The EcoTec3 engine features Dynamic Fuel Management, which allows the V8 to run on fewer cylinders during light-load cruising, improving fuel economy without sacrificing the power you need when it matters. The 10-speed transmission keeps the engine in its optimal power band, resulting in a driving experience that feels refined and responsive — far from the lumbering SUV stereotype of years past. Combined with the 4WD system, this Yukon handles Michigan roads in all four seasons with authority.

GMC Yukon SLT Features and Interior

The SLT trim is where the Yukon starts to feel genuinely luxurious. Expect features like leather-appointed seating, a heated steering wheel, heated and ventilated front seats, a power panoramic sunroof, and GMC's large touchscreen infotainment display with wireless Apple CarPlay and Android Auto compatibility.
 

Technology and Connectivity

The 2021 Yukon SLT comes well-equipped with GMC's infotainment suite, built-in Wi-Fi hotspot capability, and a premium audio system. Rear-seat passengers benefit from available rear entertainment options, and the third-row seating — now much more accessible thanks to the 2021 redesign's power-sliding second row — makes this a practical choice for larger families.
 

Safety and Driver Assistance

This Yukon comes loaded with modern safety tech including Forward Collision Alert, Automatic Emergency Braking, Lane Keep Assist, Rear Cross Traffic Alert, and a Surround Vision camera system that makes parking this big SUV in tight Detroit city spots far less stressful than you'd expect.

GMC Yukon Reliability and Ownership

The 2021 GMC Yukon has earned strong marks from owners and automotive journalists alike. The EcoTec3 5.3 V8 is one of the most battle-tested engines in the GM lineup, with a track record of reaching well beyond 150,000 to 200,000 miles with proper maintenance. The 10-speed automatic transmission, while new to this generation, has proven reliable across the broader GM and Ford truck platforms that share the unit.

Owners consistently praise the 2021 Yukon for its dramatic interior improvement over previous generations, its highway ride comfort, and its towing capability. Common maintenance items to budget for include brake service, tire rotation, and oil changes — routine costs for any V8 SUV. Overall, the Yukon SLT at 65,000 miles is the kind of vehicle where the original owner absorbed the steepest depreciation hit, and you get to enjoy years of dependable, premium driving.
