I leaned on the armrest when entering the car. It just tore off, leaving a big hole where the hinge attached. I going to wrap some wire loom around the wiring to the rear seat electrical outlet, bend some cardboad blocking in there and spray some foam inside to support the plastic and try JB Weld to stick it back together. JB Weld worked well on an air guide that cracked.
The armrest design always had too much side to side flex. One model (XC70?) has a rail on the passenger side of the console. I've wondered if offer additional support to the console lid.
