Exterior Lighting Problems of BMW Z4

I have just found out that my 2006 BMW Z4 convertible has serious wiring issues. The wires for example on my front headlights the insulation is falling off the and leaving bare wires. I am very concerned this could be a fire safety issue that could result in bare electrical wires shorting together and starting a car fire. My research shows that many people who have 2006 BMW Z4 convertibles are having this same issue. This seems to be a real issue with BMW using cheap wiring harnesses material and over time due heat and cooling is cause the insulation to fail and resulting in this issue.

The front headlight wiring harness is flaking off and could cause a short and lose your lights at night and cause a accident. There has been no recall and it's happening to all of the BMW cars that had this environmentally friendly insulation. It is a hazard because you can lose both headlights without notice and have a accident. It has been going on for years according to several mechanics I've spoken too. It also is a huge expense to replace.

Reoccuring issue: -door locks not functioning by remote or central button -wipers not functioning -trunk release not functioning by remote or button -windows not functioning -lighting of interior not working, to include gauge cluster -top not functioning issues intensify on days of low/higher temperatures. Seems to reset by disconnecting battery and reconnecting after several minutes. Issues points to gm5 module being faulty/failing this is not discovered until you start the car, seems to be a random occurrence, but happens at least once weekly. Sometimes it is multiple times a day.

Gm5 module fail. When the gm5 module fauls windshield wipers won't work (this could be a big problem if it rains!), interior lights won't work, windows won't go up or down, no alarm functions and of course no automatic door lock control (doors can manually be locked and unlocked as long as the double lock is open. ).

I left my BMW in the sun all day and now my locks wont work. Many resources link this problem to the gm5 which controls the lighting and locks. Bad locks can be a safety and security issue on parked cars but also for moving cars as children may open vehicle doors in traffic.

Passenger's airbag indication light is malfunctioned. The indication light of passenger's airbag shows always off. Therefore it can't tell the airbag is on or off.
