One problem related to wiring has been reported for the 2006 BMW X3. The most recently reported issues are listed below.
Internal headlight wiring is extremely flaking off its insulation, revealing bare wires throughout both headlights. Both sections of the light are affected, xenon and halogen. Discovered during routine bulb replacement. Merely touching the wires caused extra flaking. Seems to be a potential electrocution/fire hazard.
