Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“We purchased this H2 in december 2014 and by feb 2015 noticed a grumbly sound in the brakes. We took it in for service and the tech told us the whole undercarriage was rusted and all the brake lines were rusted thru and had to be replaced. Since some of the lines were no longer available, they had to create them. This was a costly fix and who knows what the safety impact could have been.”
NHTSA complaint #10717606, filed 2015-05, 98,651 miles“I have a major problem with leaking and rattling coming from the sunroof and now I cannot get it to function. It sounds like it might actually fly off when I am riding down the road. I have heard very many complaints on this same problem from other H2 owners. I am not worried about it working properly but I am very concerned about it flying off and causing serious injuries to my self or other people it may hit.”
NHTSA complaint #10226489, filed 2008-05, 95,000 miles“Consumer was going 70 MPH and the two front tires locked, while the two back tires kept moving. Vehicle then continued to skip. The driveshaft was replaced. For the past 8 month this vehicle has been in the shop more than at the consumer's home. The vehicle has needed a new alternator, transmission, battery,ignition and drive shaft. The roof leaked and the consumer had to replace one of the side windows.”
NHTSA complaint #10103378, filed 2005-05, 24,000 miles“Any time it rains the vehicle fills up with water. The dealer has replaced the sun roof, the gasket in the drivers door, and the cargo hatch. The electric drivers seat moves up automatically when the vehicle is turned off causing the driver to be crushed against the dash board. The consumer feels that the hood is too heavy and that there is no support bar to hold it up. The vehicle has been to the dealer seven times since the consumer purchased it.”
NHTSA complaint #10066668, filed 2004-04, 10,000 miles“Windshield wiper intermittent. Comes on without switch being activated,will not go off at all. Pulled fuse at the dealership still wouldn't go off. Was driving down the road in the rain, wipers would not function at all, however wiper fluid was rapidly spraying out at full spray and continued to spray after fluid was all gone. Bad visibility problems. Had to pull over to side of freeway in redding,ca and call local Hummer dealer which was 100 miles away. Gentleman I spoke with said he had heard of this many times. Got it fixed,and it did not remedy the problem. …”
