"takata recall" our car started flashing "increased battery discharge" and "all electrical devices will shut off" we took it to the bmw house. They diagnosed it, as needing a new battery. We replaced the battery and 1 week later the same message came on again "increased battery discharge' "all electrical devices will shut off" . We had to take it back to the bmw house and they diagnosed it this time as needing the external door handle replaced, they said the door handle had gone out and that some part in that handle puts the car to sleep but it was not allowing the car to go to sleep and this pulled the battery down. We replaced that. That lasted 2 weeks and again this same message came "increased battery discharge" "electrical devices are shutting down. I was on the way to the bmw house once again it started to smell like wires burning and under the console where the gear is started to smoke bad!! To the point that I parked the car then I called the fire department. Our car had to be hauled to the bmw house. It is unknown why all this happened.
