“I have purchased a 2003 Hummer h-2 last year in arizona. I now live in florida. My trucks steering vibrates and makes a clicking type noise when driving on poor pavement. Then the windshield wiper stopped working. I turned the vehicle off and on. The windshield wiper started working, but the windshield wiper washer keeps spraying cleaner on the windshield. I had to remove the relay to make it stop. The rear window washer keeps spraying cleaner on the window also. I called a chevorlet dealer in florida and told them about the problem. …”
NHTSA complaint #10228809, filed 2008-05, 63,000 miles“My right front wheel, inner backing and axle came off. The lower flange broke away from the lower a-arm. This happened while I was driving on a paved road near my house. The a-arm hit the ground and spun the H2 off the road and into a tree. The right wheel's brake backing plate and axle came off all in one piece. Except for this one flange, the remainder of each front wheel is held in place by only ball joints. The upper flange is attached to a ball joint. The lower flange is a major structural component of the front end. …”

NHTSA complaint #10110806, filed 2005-02, 5,686 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. …”
NHTSA complaint #10241626, filed 2008-09, 61,000 miles“Driving down highway 64 east mile marker 261... Driving down the road in 03 Hummer H2 and was cut off. My speed was 70, their speed was 55. Slammed on brakes and attempted to drive around person that cut me off. When I hit the brakes went into a skid (I think I lost my steering on the right front tire, still skid marks on road). Held the skid for 600 feet(?) at which point I lost control. Drove into ditch and attempted to do a 180 and back into the woods because I was going up a hill and the ravine on either side was getting very deep and there was a bridge coming up. …”
