It is good to know that I am not the only one with the door hinge problems. I have had it fixed by the dealer twice and they said next time it happened I would have to pay out of pocket. I told them I was a mechanical engineer and have an understanding of strengths of materials and mechanical designs. I said he rear door hing is not adequate for the weight of the rear door and tire.
Overall, thusfar, I like my Rubicon. However, the rear hinge has been a problem. As a result of repairing the door hing, the plastic lining in the back rattles when I play music with bass. Also, I have had to replace two tail light assemblies that were broke for the real door opening too far.
Finally, and unrelated, the GPS is horrible. I expected more from a brand new vehicle days.
Does anybody have a solution?
