Battery Problems of BMW 7 Series

My complaint is with 2007 BMW 750li model. There is an energy parasite in the vehicle's electrical system. It has been narrowed down/pointed out as the "comfort access system" by other owners. This comfort access system does not shut-down completely when parked and drains the battery. Energy drain also occurs during the vehicle operation and the vehicle shuts down a/c blower frequently to conserve energy. It required me to jump start the vehicle on numerous occasions. I have taken the vehicle to BMW dealers on three different occasions and besides changing the battery, nothing much has been addressed. Even after new battery, loss of energy still persists. There are many complaints on the web regarding this issue. BMW would not proactively address the issue, unless the diagnostics system directs them to a specific area/areas. My vehicle currently is not pointing to any errors, so BMW shrugs away and asks me to live with it. In the meanwhile, it is an unreliable and unsafe vehicle to operate. Presently, the loss of energy is resulting in blower or other energy consuming device shutdown, and requiring a jump for vehicle start up. If this phenomenon gets worse, the vehicle can loose power completely during operation and shutdown, leading to a very unsafe condition, especially, on highways it can lead to fatal accidents. I would like this safety issue to be addressed by nhsta. I am available anytime to provide any additional information. This issue has been reported to BMW dealrs at mt. Laurel, NJ and alexandira, va, and customer service and is fully documented by them.
