  • Reliability (4)
    4 out of 5 stars
    GMC heavy-duty trucks generally have a strong reputation for reliability, especially with their robust powertrains. While new technology always carries a slight risk, the core mechanicals are proven and built to last under demanding conditions.
  • Maintenance (3)
    3 out of 5 stars
    As a heavy-duty truck with advanced features and powerful engines, maintenance costs can be higher than average. Specialized parts and labor for diesel engines and complex systems contribute to the expense, though routine maintenance is straightforward.
  • Technology (5)
    5 out of 5 stars
    Packed with cutting-edge technology, including a large infotainment screen, advanced driver-assistance systems, a comprehensive camera system for towing, and wireless connectivity, the Sierra 3500HD Denali provides a modern and convenient user experience.
  • Comfort (5)
    5 out of 5 stars
    The Denali trim excels in comfort, offering a plush and quiet cabin. High-quality materials, heated and ventilated seats, and a well-tuned suspension soak up road imperfections, making long journeys surprisingly pleasant for a truck of this caliber.
  • Dynamics (4)
    4 out of 5 stars
    Given its size, the Sierra 3500HD Denali handles remarkably well. Steering is precise for a heavy-duty truck, and body roll is managed effectively, especially when unladen. The powerful engine provides ample acceleration and towing capability.
