- Reliability (4)4 out of 5 starsGMC heavy-duty trucks generally have a good reputation for reliability, and the 2025 model is expected to continue this trend. While it's a new model year, the underlying components are proven. Early indications suggest strong build quality.
- Maintenance (3)3 out of 5 starsAs a large, heavy-duty truck with advanced features, maintenance costs can be higher than average. Parts are often more expensive, and specialized fluids or services may be required. Fuel economy, while decent for its class, will also contribute to running costs.
- Technology (5)5 out of 5 starsGMC has packed the Denali Ultimate with cutting-edge technology. The large infotainment screen is intuitive and responsive, and features like the multi-view camera system and advanced trailering tech are incredibly useful for heavy-duty tasks.
- Comfort (5)5 out of 5 starsThe Denali Ultimate trim lives up to its name in comfort. The seats are exceptionally supportive and offer plenty of adjustments, making long hauls a breeze. The cabin is well-insulated from road and wind noise, providing a serene environment.
- Dynamics (4)4 out of 5 starsFor a heavy-duty truck, the Sierra 3500HD Denali Ultimate handles surprisingly well. It feels stable on the highway and the steering is more precise than expected for its size. It's not a sports car, but it's competent for its class.
