Wire harness, that passes through rubber articulated gasket that connects between vehicle body and rear hatch door of wagon, suffers from wire fatigue that causes individual wire insulators to crack and conducting wires to break, leading to failure of critical automobile safety equipment; namely, rear wiper motor, rear back-up lights, rear middle brake light, rear license plate lights, rear window defroster. this design defect has be reported by numerous owners and has been documented on youtube (https://www.youtube.com/watch?v=amekptvgmhs) and outback owners' bulletin board websites (http://www.subaruoutback.org/forums/66-problems-maintenance/20718-rear-wiper-does-not-return-park-home-position.html). probable manufacturing defects include: (i) orientation of rubber articulated gasket through which rear door wiring harness passes is such that it causes undue flexing of wire harness wires upon open / close sequence of rear tailgate, and (2) defective and/or undersized wire harness wires unable to withstand the open / close sequence of rear tail gate.
