Alternator/generator/regulator problems of the 2007 BMW 3 Series

When driving, the smell of burning or melting plastic is so strong, I have to roll down the windows. The smell occurs about 5 times a week and can be smelled both inside and outside the car. It occurs at various times. . . On the freeway, on surface streets, stopped at a red light etc. There is a safety recall, for positive crankcase ventilation(pcv) valve heater, but they don't have a plan or method of fixing this. Since it can lead to a fire, it needs to be fixed, but the dealership has no information about even how to fix the problem. The website and letter tells you to call the local dealership but they tell you to contact BMW north America, however they don't answer the phone. The service supervisor at the local BMW dealer ship in glendale CA has not returned my messages and the number they refer me to, BMW north America at 800. 831. 1117 just keeps ringing. . . No answer. I don't feel safe inhaling the plastic fumes and it could lead to my car catching on fire. BMW needs toanswer questions and provide customer service rather than referring me to advertisements to purchase a new BMW. (that is what happens on their "recall" website). I would like them to provide a car and keep my car at the dealership until they figure this out. I think they would find a solution very quickly if they had to provide alternator transportation. Thank you for your help!.
