“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.”
