* Based on opinions and should be considered as general guidance only.
- Reliability (3)3 out of 5 starsWhile GMC trucks generally have a solid reputation, the AT4X's more complex off-road systems could introduce potential points of failure over the long term. Owners report good initial reliability, but long-term data for this specific configuration is still developing.
- Maintenance (3)3 out of 5 starsRoutine maintenance is standard for a full-size truck. However, the specialized off-road components of the AT4X may require specific expertise or parts for any non-routine repairs, potentially increasing costs or downtime.
- Technology (4)4 out of 5 starsGMC offers a comprehensive suite of modern tech, including a large infotainment touchscreen, wireless Apple CarPlay/Android Auto, and a good selection of driver-assistance features. Some competitors might offer slightly more intuitive interfaces.
- Comfort (4)4 out of 5 starsThe interior is well-appointed and spacious, with comfortable and supportive seats. Road noise is generally well-managed, making for a pleasant experience on longer journeys.
- Dynamics (4)4 out of 5 starsThe AT4X trim offers impressive off-road capability with its Multimatic DSSV dampers and locking differentials, providing a commanding and stable ride even on rough terrain. On-road manners are also refined for a truck of its size.
