1999 BMW 528I User Comment / Complaint

I have a 1999 bmw 528it wagon. until a month ago my husband had a 1994 bmw 318ic. all four headlight lenses in these cars became quite filmy, and have been for some time, which i believe to be a significant safety hazard, as it diminished the ability to see at night. these cars were not antiques, and the safety equipment should hold up for a minimum of 10-15 years, in my opinion. will you please make bmw do something to remedy this situation at the company's expense, not the owner's? i have a 1989 volvo, and its lenses are still fine, so this is not something that happens in all cars.
