- Reliability (4)GMC Yukons generally have a good reputation for reliability, and the 2018 model is no exception. Major powertrain components are robust, and common issues are relatively minor and infrequent.
- Maintenance (3)Maintenance costs are typical for a full-size SUV. Parts can be more expensive than smaller vehicles, and fuel economy, while decent for its class, means higher running costs. Routine servicing is straightforward.
- Technology (4)The infotainment system is user-friendly with a responsive touchscreen and good connectivity options including Apple CarPlay and Android Auto. Standard safety features are decent for the year, though advanced driver aids are often optional.
- Comfort (4)Comfort is a strong suit, with spacious seating across all three rows, especially in the XL version. The ride quality is generally plush, absorbing most road imperfections well. Front seats are supportive for long drives.
- Dynamics (3)The 2018 GMC Yukon XL SLT Standard Edition offers a generally smooth ride for its size, but handling can feel a bit ponderous, especially in tighter turns. The steering is light, which helps with low-speed maneuvering, but lacks significant feedback.
