- Reliability (4)4 out of 5 starsGMC heavy-duty trucks generally have a strong reputation for reliability, especially the robust Duramax diesel engine. While it's a new model year, the underlying platforms and powertrains are proven, suggesting good long-term dependability.
- Maintenance (3)3 out of 5 starsMaintenance costs for heavy-duty trucks, especially diesel variants, can be higher than standard vehicles due to specialized parts and fluids. However, the service intervals are typically long, and the widespread dealer network makes servicing convenient.
- Technology (5)5 out of 5 starsGMC has packed the 2025 Sierra 3500HD AT4 with cutting-edge technology. The infotainment system is intuitive and responsive, featuring a large touchscreen, wireless Apple CarPlay/Android Auto, and a host of advanced trailering technologies and driver-assist systems that enhance safety and convenience.
- Comfort (4)4 out of 5 starsThe AT4 trim offers a comfortable and well-appointed interior. The seats are supportive for long hauls, and the cabin is relatively quiet, isolating occupants from road and wind noise. The ride quality, while firm due to its heavy-duty nature, is more refined than expected.
- Dynamics (4)4 out of 5 starsGiven its size, the Sierra 3500HD AT4 handles surprisingly well, especially for a heavy-duty truck. The steering is responsive, and body roll is managed effectively for its class. It feels stable and confident on the highway and capable off-road.
