  • Reliability (4)
    4 out of 5 stars
    GMC generally has a good reputation for reliability, and the 2021 Yukon XL is expected to follow suit. Early reports suggest solid build quality, though long-term data is still accumulating.
  • Maintenance (3)
    3 out of 5 stars
    As a large, full-size SUV with advanced features, maintenance costs can be higher than average. Fuel economy, while improved, still reflects its size and V8 engine, leading to higher running costs.
  • Technology (4)
    4 out of 5 stars
    Equipped with a large infotainment screen, wireless Apple CarPlay/Android Auto, and a host of driver-assist features, the technology suite is modern and user-friendly, though some advanced features are optional.
  • Comfort (5)
    5 out of 5 stars
    The interior is spacious and well-appointed, providing excellent comfort for all passengers, even in the third row. The ride quality is smooth, absorbing most road imperfections with ease.
  • Dynamics (4)
    4 out of 5 stars
    Despite its large size, the Yukon XL AT4 offers surprisingly capable off-road dynamics and a stable, if not sporty, on-road feel. The independent rear suspension significantly improves handling over previous generations.
