- Reliability (3)The Vortec 6.0L V8 and heavy-duty transmission are robust, though the vehicle is frequently plagued by air suspension leaks and minor interior trim failures.
- Maintenance (2)Ownership costs are high due to extremely poor fuel economy, the high cost of oversized tires, and the premium price of specialized heavy-duty components.
- Technology (2)Reflects standard 2004 GM parts-bin engineering; it features a basic Bose sound system and dual-zone climate control, but the optional navigation system is now obsolete.
- Comfort (4)The cabin is exceptionally wide and features plush leather seating with a high command seating position, offering a smooth, truck-like ride that absorbs bumps well.
- Dynamics (2)While highly capable off-road, the H2 feels sluggish and ponderous on pavement with significant body roll and a 0-60 time that struggles to keep up with modern traffic.
