| EA05017 | GENERAL MOTORS CORP. | 10/28/2005 | 04/30/2007 | HUMMER H2 STEERING KNUCKLE FAILURES | ||
| Odi upgraded this investigation at the conclusion of pe04-080.the alleged defect involves the failure of the steering knuckle at the lower ball joint boss, resulting in a separation of the lower ball joint from the knuckle.a lower ball joint separation could result in a loss of steering and/or a disabled vehicle. it appears that the fractures of h2 steering knuckles can be attributed to wheel/tire collision forces being transferred directly to the steering knuckle.the original knuckle design appears to be sufficient for the h2 application.evidence from inspected vehicles, photographs, police reports and edr data indicates collision impact events placed stress on the steering knuckle causing it to fracture.further use of agency resources does not appear to be warranted.the closing of this investigation does not constitute a finding by nhtsa that no safety-related defect exists with regard to the subject component.the agency reserves the right to take further action on this issue if warranted. | ||||||

| 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. i flipped once but knocked both front tires off. i drive a lot(150 miles a day on average) and have never had a wreck. this was ridiculous, i feel like i clearly lost my steering on my front right(passenger side) and the more i think about it the more i feel like that's what happened. well the trucks totaled so nothing that can be done to fix it... on the up hand i walked away from a pretty bad accident with only aches a and pains. *jb | |||

| While turning right at 30 mph the front end dropped down. this caused consumer's vehicle to hit a parked vehicle. the vehicle was towed. dealership was notified, but did not resolve the problem. *ak | |||

| Lifted vehicle was taken into have a leaking upper driver's side cv boot replaced. when the axle was removed, it was discovered that the axle had been destoyed and the pieces punctured the cv boot internally causing the leak. this is the 2nd time in a little over 600 miles that this boot needed to be replaced. when the cv boot was last replaced, there was no noticable damage to the axle. was informed by a gm tech today that the damage may have occured when the axle was reinstalled. now i have been informed by the dealership that the gm factory rep has denied warranty coverage. vehicle has been lifted and dealership attributes the damage to the lift and the angle of the axles. vehicle is not used off-road and 4x4 option is not used. other h2's on www.h2source.com have had similar problems but this was due to off-road usage. *mr | |||

| 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 http://www.sacbee.com/content/business/auto/story/5721689p-6694625c.html *la | |||

| Dt*: the contact stated while driving over bumps in the road at various speeds the force of the bumps are felt within the vehicle. the vehicle sags on the passenger side due to the torsion bar losing it's spring. the dealer has replaced the torsion bar but the problem recurred. | |||
