Engine
6.6L V8* Based on opinions and should be considered as general guidance only.
- Reliability (4)4 out of 5 starsGMC's heavy-duty trucks are generally known for their durability. The 3500HD platform has a proven track record for tackling tough jobs. While long-term data for the 2026 model is unavailable, expectations are high based on previous generations.
- Maintenance (3)3 out of 5 starsAs with any heavy-duty pickup, maintenance costs can be higher due to larger components and more robust systems. Regular oil changes, tire rotations, and fluid checks are crucial. Finding specialized technicians for certain repairs might also be a consideration in some areas.
- Technology (4)4 out of 5 starsGMC has packed the Sierra 3500HD AT4 with modern tech. The infotainment system is user-friendly with a large touchscreen, and features like trailer assist cameras are invaluable. Apple CarPlay and Android Auto are standard. Some advanced driver-assistance systems are optional, which is a minor drawback at this price point.
- Comfort (4)4 out of 5 starsThe cabin is well-appointed and surprisingly quiet for a heavy-duty truck. Seats are supportive, and the ride quality is manageable even when unloaded. However, road noise can intrude on longer journeys, and the sheer size of the truck can make parking a challenge.
- Dynamics (4)4 out of 5 starsThe Sierra 3500HD AT4 offers immense towing and hauling capability. While not as agile as a smaller truck, its powerful engine and robust suspension handle heavy loads with confidence. Off-road performance is commendable, with the AT4 package providing excellent ground clearance and traction.
