2003 Hummer H2 Owner Comments

problem #1

Sep 042003

H2 4WD 8-cyl

  • Automatic transmission
  • 2,500 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. There was no impact to any of the parts of the right wheel assembly or axle even after I was thrown off the road. Obviously the brake line and ABS circuit was severed immediately. I had no brakes and little other control. After the H2 hit the tree, it came to a stop. The bottom of the tree stayed stationary, but the top of the tree broke off and came down (hard) on the right windshield post, bending the post and shattering the windshield. With no front wheel, the H2 does not have any mobility except for skidding and sliding. This is the third case of this same type of defect reported to the website "www.H@source.com" it was suggested that I report it to you. There was an article in the sacramento bee about this type of defect. Please see "www.sacbee.com/content/business/auto/story/5721689P-6694625C.html"
