- Reliability (4)The GMT800 platform is legendary for its durability, with engines and transmissions frequently reaching 250,000+ miles, though minor interior trim and electronic failures are common.
- Maintenance (4)Parts are incredibly abundant and inexpensive due to the shared platform with the Silverado and Suburban, making it easy and affordable to service at most shops.
- Technology (2)By modern standards, the technology is very dated, featuring basic analog gauges, a simple CD/cassette player, and early-generation OnStar systems.
- Comfort (5)With its massive cabin, plush SLT leather seating, and a soft suspension setup, it remains one of the most comfortable long-distance cruisers for large families.
- Dynamics (3)The 5.3L Vortec V8 provides solid towing power and smooth acceleration, but the vehicle suffers from significant body roll and a numb steering feel typical of large, truck-based SUVs.
