One problem related to tailgate hinge has been reported for the 2000 Chevrolet Suburban. The most recently reported issues are listed below.
Rear back glass is detaching itself from the molding that holds the window to the hinges of the vehicle. I had the local Chevrolet dealer look at the window and they told me that it was normal wear and tear. I know that this is not normal for a vehicle of this age,(only 4 years old when problem found). Nothing has been done to fix this but I think that there should be a recall by GMC since I've talked with body shops in this area and this is not the first time they have seen this type of problem. For safety if this window were to separate while you are driving it may possibly cause a mishap on the road.
