2015 BMW 328I Structurebody Problems

INTERMITTENTLY IT IS NOT POSSIBLE TO OPEN THE DOORS FROM THE INSIDE OF MY VEHICLE USING THE DOOR HANDLE.. THE DOOR REMAINS LOCKED AND WILL NOT OPEN FROM THE INSIDE BY PULLING THE DOOR HANDLE. THE ONLY KNOWN WORKAROUND IS TO FIND THE "UNLOCK ALL DOORS" BUTTON ON THE DASHBOARD TO UNLOCK THE DOORS AND IT'S NOT CLEAR THAT THIS IS A VIABLE SOLUTION FOR ALL CASES. HERE IS A VIDEO OF THE ISSUE: HTTPS://WWW.YOUTUBE.COM/WATCH?V=V7_UBSGJTQQ THIS IS A WIDESPREAD ISSUE FOR THE F30 GENERATION OF BMW PASSENGER CARS (2011'2019). WHAT I 'M TRYING TO UNDERSTAND IS: HOW IS SOMETHING THIS CRITICAL TO SAFETY (BEING ABLE TO EXIT THE VEHICLE, ESPECIALLY IN AN EMERGENCY) NOT SUBJECT TO A RECALL OR A AT THE VERY LEAST A TSB? I WAS TOLD THAT THIS REPAIR FOR MY VEHICLE WHICH IS JUST OUTSIDE OF THE FACTORY WARRANTY WOULD COST OVER $1000. SEE THE FOLLOWING...

REAR SPOILER MALFUNCTION APPEARED ON MY SCREEN WHILE I WAS DRIVING ROUGHLY 30 MILES PER HOUR, THEN THE REAR SPOILER BEGAN TO SMOKE WITHIN 60 SECONDS. I PULLED THE CAR OVER TO PARK IT, AND AFTER ANOTHER 100 SECONDS, THE SPOILER CAUGHT FIRE AND WITHIN 180 MORE SECONDS THE WHOLE REAR OF THE CAR WAS ON FIRE. BY THIS TIME THE FIRE DEPARTMENT SHOWED UP AND EXTINGUISHED THE FLAMES.
