MY CAR HAS SUDDENLY LOST POWER IN SEVERAL OCCASIONS NEARLY CAUSING AN ACCIDENT AT 60 MPH ON ONE OCCASION. WHEN POWER IS LOST STEERING SEIZES UP COMPLETELY. THIS HAPPENS WITH ABSOLUTELY NO WARNING WHATSOEVER & MY CAR HAS STARTED UP AS THOUGH NOTHING IS WRONG AFTER. THE SECOND ISSUE IS SO WELL KNOWN IT HAS BEEN LABELED AS THE "TERRIBLE TRIAD" AC ROAD ALL BMW FORUMS, YOUTUBE. TWITTER, ETC. YOU CAN FIND THOUSANDS OF CHATS & FORUMS DISCUSSING THE 3 LIGHTS WHICH APPEAR SIMULTANEOUSLY DUE TO TRANSFER CASE ACTUATOR & I DRIVE ISSUES. MY 4X4 LIGHT IS ON INDEFINITELY & ALL OF THE SYMPTOMS CAN BE FELT.
