We have a 2019 3120. The bathroom pivot door started making a groaning noise as we opened and closed the door. I found the top pivot hinge attachment to the door was to tight causing the door to hang from the top hinge. This put a bending torque on the pivot bar in the door jam (groaning noise). I adjusted the top hinge attachment letting the door ride on the bottom hinge and the top to be just a guide.
