“I have a 2008 Hummer h-3. On november 3rd 2009 while driving about 30 miles an hour on a sharp left curve, there was a loud clunk in the front end and the truck pulled hard to the right making the vehicle go down into the ditch. Several week before this incident while in a parking lot making a sharp left turn( less than a mile per hour) there was a real loud clunk in the front passengers side, this happen twice including a week before the failure. When I checked under the front end I did not see anything. The vehicle was taken to the Hummer dealer but they could not tell if anything failed. …”
NHTSA complaint #10295189, filed 2009-12, 11,000 miles“I was not involved in an incident. The rear frame of this vehicle has rusted 90% away. if it were driven any further the rear axel will fall off. I was towing a boat and it and the axel and rear bumper could have flown off the vehicle. I had no idea the extent of damage. I've owned the vehicle for 11 years. I've read that other Hummer h3 owners have had the axel fall off. Please let other Hummer h3 owners know how severe this can be. Every northern tier state vehicle 2008 and older with 146,400 miles can not have this dangerous of a situation. …”
