Alternator/generator/regulator Problems of BMW 550

Our car's electrical panel lit up before the car stalled on two separate occasions. The first time, BMW replace the battery. The second time, BMW replaced the alternator. 12 days after being serviced by BMW, our house burned down due to a fire originating on the front left side of the BMW. That afternoon, my husband had come home from work, parked the car in the garage, and turned it off. The fire started within 30minutes of being shut off and parked. We received a letter in the mail informing us our BMW was under recall for a malfunctioning fuel pump injector.

My 2011 BMW 550i has thrice had this weird response in the past 6 months. After driving for 30m-1h suddenly got multiple different warning lights before I lost control of steering (stiff like a dead body) and brakes following which the car stalled. It was towed to the dealership who said this was a bad battery which did not make sense but the car was running thereafter so I took it home. The second time the dealership was closed - I was able to start the car a few minutes later and took the risk of driving home. The dealership said since the car was running they could not run any diagnosis. Thereafter the car ran fine for 3 weeks and then it happened again. This time I could restart it but the car would only move a few feet before stalling. After towing it to the dealer they tell me that the battery and alternator both are bad. I can understand that but there should never be a total loss of control on steering and brakes. That to me is a safety issue and BMW needs to fix it but the dealership does not seem to know what to do. They just want to fix the battery and alternator and call it "problem resolved" without digging further. I have not seen any recalls either. I am now afraid to drive the car because it could get me killed.
