Hummers are designed to tackle off-road conditions and severest of weather situations. Adhering to the regular maintenance timetable and replacing broken parts as soon as possible will keep your H2 running for 300,000 to 500,000 miles without any big fixes.
Overall, the buying experience was very nice. The car was able to take us on long trips from Maharashtra to Goa and Hampi without any issues. After 6 years, the engine is still running strong with no problems. We purchased the 8-seater petrol variant and it looked really good. It is great on highways and the service by Chevrolet has been great. Although they have stopped selling the car, they still provide good service and parts availability. The car's average performance is what we would expect from an 8-seater MPV, but the ground clearance is a bit low.
