About This 2021 GMC Yukon SLT

The 2021 model year marked a major generational redesign for the Yukon, bringing an independent rear suspension, a significantly longer wheelbase, and a vastly improved interior over the previous generation. This isn't just any used SUV — it's a comprehensively reimagined truck-based hauler that genuinely competes with premium three-row SUVs. Finished in a sharp Black exterior, this SLT trim sits confidently in the middle of the Yukon lineup, offering a long list of upscale features without the fully loaded Denali price tag. At 116,500 miles, this Yukon is well into its working life but built to go considerably further with proper care — something GMC full-size SUVs are well known for.

2021 GMC Yukon Performance and Engine

5.3L V8 Power and Real-World Capability

Under the hood sits GMC's proven 5.3L V8 OHV engine, producing 355 horsepower and 383 lb-ft of torque. Paired with a smooth 10-speed automatic transmission, this powertrain delivers confident acceleration, effortless highway merging, and the towing capacity — up to 8,500 pounds — that makes the Yukon genuinely useful for hauling boats, trailers, or campers up through northern Michigan or across the Midwest. The V8 also benefits from Dynamic Fuel Management, which can deactivate cylinders under light load to improve fuel economy on long drives. Whether you're navigating I-75 through Detroit, heading up to Traverse City, or making a run out to Ann Arbor, this engine never feels strained.

GMC Yukon SLT Features and Interior

What the SLT Trim Delivers

The SLT is where the Yukon lineup starts to feel genuinely luxurious. Expect leather-appointed seating for up to nine passengers, a power-adjustable driver's seat, heated front seats, a large infotainment touchscreen with Apple CarPlay and Android Auto compatibility, and GMC's available rear-seat entertainment options. The 2021 redesign brought dramatic interior improvements — the third row now has real adult-usable legroom thanks to the extended wheelbase, and available power-folding second and third rows make loading cargo effortless. Dual-zone automatic climate control, a premium Bose audio system, and a power liftgate round out a feature set that makes daily family life easier across the board.

GMC Yukon Reliability and Ownership

What to Expect as a Yukon Owner

The GMC Yukon has one of the strongest long-term reliability reputations in the full-size SUV segment. The 5.3L V8 is a workhorse engine with decades of refinement — it's not unusual to see these motors run well past 200,000 miles with routine oil changes and maintenance. The 2021 generation also addressed one of the previous Yukon's biggest criticisms by replacing the old solid rear axle with an independent rear suspension, improving both ride quality and cargo floor configuration. Common ownership considerations include keeping up with transmission fluid services, brake inspections given the vehicle's weight, and monitoring the air suspension if equipped. Overall, buyers in Wayne County and across Metro Detroit consistently report high satisfaction with the Yukon's dependability over the long haul.
