Recently reported ELECTRICAL SYSTEM problems on 2009 Porsche Cayenne

During normal commute to work driving, a message "check dim beam" appeared on the dashboard message board. upon attempting to change a faulty dim beam headlamp bulb, i found headlamp harness wiring and all internal headlamp assembly wiring is cracked and crumbling and conductors are exposed and causing shorts and apparent lamp failure. other headlamp lighting (side directional lamp) lighting flashed on and off when harness was touched, and other components of electrical system flashed and turned off and on by themselves, particularly the radio. when the suspect dim beam lamp was swapped with opposite (passenger side, the replacement lamp did not work but the suspect lamp from driver side worked on the passenger side leading me to believe the lamp assembly was suspect. upon opening the access points on the drivers side assembly, the wiring was seen to be crumbling and unsafe. i am worried that a fire may start and have discontinued use of the vehicle at this time.

Vehicle was parked in garage. went to use it, opened door to drivers side, dash reads ignition lock fault. would not start, would not come out of park. towed to dealer (after towing co. did emergency unlock of transmission to get out of garage. vehicle has been at porsche dealership for a week now, told at first ignition switch was bad. replaced and still not functioning (no start) now told control module must be replaced as it got "wet" and vehicle interior floor had gotten wet. research on internet shows many other people have had this problem with electrical components getting wet from a defect in car. *tr

The electronics on the car are showing a suspension issue. and the electronics on the car do not work for more than 5-7 min before shutdown and restart. this includes radio, bluetooth, gps, etc. when the electronics start back up the radio is turned on. *tr
