- Reliability (4)GMC Yukons generally have a good reputation for reliability, and the 2018 model continues this trend. Major issues are uncommon if properly maintained.
- Maintenance (3)Maintenance costs are typical for a full-size SUV. Parts can be more expensive than smaller vehicles, and fuel economy is a significant factor in overall running costs.
- Technology (4)The infotainment system is user-friendly with good features like Apple CarPlay/Android Auto. Safety features are adequate for the year, but not class-leading.
- Comfort (4)The interior is spacious and comfortable, especially for long trips. The ride is smooth, absorbing most road imperfections effectively. Third-row seating is decent for its class.
- Dynamics (3)Given its size, the Yukon XL SLT handles reasonably well for a large SUV, but don't expect sporty dynamics. It's built for cruising, not cornering.
