* Based on opinions and should be considered as general guidance only.
- Reliability (4)Built on the proven GMT800 platform, the engine and transmission are notoriously robust, though owners should watch for minor electrical issues and air suspension failures.
- Maintenance (3)Mechanical parts are widely available and relatively affordable due to shared components with the Tahoe/Yukon, but poor fuel economy and premium part costs for Cadillac-specific trim can be high.
- Technology (3)While it featured cutting-edge tech for 2006 like a Bose sound system and rear-seat entertainment, the infotainment interface and navigation system now feel very primitive.
- Comfort (4)Exceptional seat cushioning and a quiet cabin provide a luxurious ride, though the third-row seating is somewhat cramped and lacks the refinement of the front captain's chairs.
- Dynamics (3)The 6.0L V8 offers impressive straight-line power for its size, but the soft suspension and high center of gravity lead to significant body roll and a disconnected steering feel.
