- Reliability (4)GMC Yukons generally have a good reputation for reliability. The 2018 model is considered solid, with common issues being relatively minor and well-documented. Regular maintenance is key to its longevity.
- Maintenance (3)Maintenance costs for a full-size SUV like the Yukon can be higher than smaller vehicles due to larger components, more fluids, and potentially higher labor rates. Fuel economy is also a significant ongoing cost, especially with the V8 engine.
- Technology (4)The SLT trim comes with a good array of technology, including an intuitive infotainment system with an 8-inch touchscreen, Apple CarPlay, Android Auto, and multiple USB ports. Safety features like front and rear parking sensors and a rearview camera are standard, with more advanced options available.
- Comfort (4)Comfort is a strong suit, with a spacious and well-appointed interior. The ride quality is generally smooth, especially on highways, soaking up most road imperfections. Seats are supportive, though the third row is best for children or short trips.
- Dynamics (3)The 2018 GMC Yukon SLT offers decent straight-line performance with its V8 engine, but its large size and body-on-frame construction lead to noticeable body roll and less agile handling compared to crossovers. The steering can feel a bit numb.
