The symptom was caused by the supply wires to the igniter losing there insulation at stressed harness attachment point, arced over, and caused the copper conductors to become brittle. This symptom was seen on the projector assembly wiring as well as the daylight running light which did not exhibit the copper breakdown. …”
NHTSA complaint #10926533, filed 2016-11, 114,000 miles“The adaptive bixenon headlights use biodegradable wiring. This wiring cannot withstand the headlights adaptive headlight movement.
