The hinge for the rear liftgate window failed. There is a horizontal crack across the hinge. It appears to be metal fatigue. This failure is a safety hazard for the following reasons: 1) the window no longer seals properly and could allow exhaust gases to enter the vehicle cabin, resulting in carbon monoxide poisoning. It is very possible that this failure would not be detected immediately. 2) the hinge failure causes additional strain on the remaining hinge and latch. Further failure would result in the window detaching from the vehicle. A) if this occurred while driving, the window could impact vehicle behind the Suburban or shatter on the roadway leading to debris related accidents. B) if this occurred while stationary, the glass could (which is heavy and sharp edged) could injure a person standing or walking at the rear of the vehicle. This exact same failure occurred previously on this vehicle at ~ 13000 miles of operation. The repair was made by a dealer at no charge to the owner. The recent recurrence of the failure of the same hinge occurred at ~107000 miles. The problem was reported to General Motors customer service and was logged as service request # 71 743 851 820 by jatta flores. Jatta denied owner's request that GM repair the defect.
