- Reliability (4)4 out of 5 starsGMC trucks generally have a good reputation for reliability, and the Sierra 1500 AT4 is expected to continue this trend. While new models can have minor initial quirks, major issues are uncommon.
- Maintenance (3)3 out of 5 starsMaintenance costs for a full-size, off-road capable truck like the AT4 can be higher than average due to specialized components (tires, suspension) and potentially higher labor rates. Fuel economy, while improved, still contributes to overall running costs.
- Technology (5)5 out of 5 starsGMC has packed the AT4 with cutting-edge technology, including a large infotainment screen with wireless Apple CarPlay/Android Auto, numerous driver-assist features, and an available head-up display. The camera system is particularly useful for trailering and off-roading.
- Comfort (4)4 out of 5 starsThe interior is well-appointed with comfortable leather seats and a spacious cabin. The ride quality is surprisingly smooth for an off-road oriented truck, though some road imperfections can be felt more than in less aggressive trims.
- Dynamics (4)4 out of 5 starsThe 2025 GMC Sierra 1500 AT4 offers impressive off-road capability with its lifted suspension and knobby tires, yet maintains decent on-road manners for a truck of its size. Steering is responsive, and the powerful engine provides ample acceleration.
