Without any accident, under normal usage, the vehicle's license plate lights failed. The problem was traced to a break in a conductor (wire) contained in a wiring harness that connects the vehicle to the rear hatch through a rubber bellows. Once the bellows was retracted, the broken wire was found along with twelve (12) other wires that were all nearly broken: their insulation was cracked and several wires ultimately broke completely upon further flexing. These other wires fed the brake lights, turn signals, running lights, hatch lock, and all other electrical circuits on the rear hatch. It appears that the insulation on this wire does not hold up in this environment and will ultimately fail in the course of several years. This poses a safety problem as the vehicles rear lights (turn signals, brake lights, etc. ) can fail at any moment.
