2016 BMW 340I Electrical System Problems

MY CAR IS ACTUALLY A 2017 BMW 340I BUT THE SYSTEM DID NOT ALLOW ME TO CHOOSE THAT CAR. I HAD THE AUTO-START/STOP FEATURE ENGAGED AND THE CAR STALLED ONCE I CAME TO A COMPLETE STOP. I WAS DRIVING ON A STREET AT THE TIME. I HAD TO RESTART THE ENGINE BUT IT WOULDN'T START COMPLETELY OFF. I DISABLED THE FEATURE AND IT STOPPED DOING THIS. LATER ON JULY 5TH, THE CAR SIMPLY STOPPED STARTING ALL TOGETHER. AT THIS TIME I WAS PARKING IN MY PARKING GARAGE AT HOME AND WHEN I TURNED THE CAR OFF I TRIED STARTING IT BACK AND IT NO LONGER WORKED.

ON THE FIRST OCCASION IT LURCHED FORWARD AT A HIGH RATE OF FORCE AND HIT A FENCE AS I WAS PULLING IN SLOWLY TO PARK - I COULD NOT CONTROL IT WITH THE BRAKE UNTIL I PUT IT IN REVERSE; ON SECOND OCCASION (2 WEEKS LATER), I WAS ON A CITY STREET SLOWING TO 5MPH AND STOPPING AT A RED LIGHT AND SUDDENLY WHILE I WAS FULL FOOT ON BRAKE THE CAR WAS REVVING AND BUCKING AND I COULD NOT CONTROL IT UNTIL I THREW IT INTO PARK. FOOT HARD ON THE BRAKE THE WHOLE TIME. BOTH TIMES DRIVING COMPLETELY STRAIGHT AND VERY SLOWLY INTO...
