A hinge member comprises a mounting portion to be secured to a vehicle body panel, and an extension portion having a fixed orientation relative to the mounting portion. The extension portion has a pivot-receiving slot defining a hinge pivot hole to receive a hinge pivot, and a slot portion extending from the hinge pivot hole. At least a portion of the pivot-receiving slot has a lateral dimension smaller than a diameter of the pivot hole. A hinge assembly includes a first hinge member pivotally joined to a second hinge member by a hinge pivot having a hinge pivot pin in a pivot pin bushing. Preferably, the pivot pin bushing shears under a pre-selected level of force or load to permit the pivot pin to be slidingly received in the slot. Embodiments of the hinge assemblies are well suited for hingedly mounting motor vehicle body panels to the vehicle body.
