DOOR LATCH FAILURE. NOTICED PROBLEM WITH DOOR AJAR LIGHT LIT FOR A COUPLE DAYS. SUBSEQUENT BATTERY DRAINING PROBLEMS. SEEMS DUE TO KEEPING LIGHTS ON IN CAR BECAUSE IT THOUGHT DOORS WERE OPEN EVEN THOUGH THEY WERE SECURELY SHUT. WITHIN COUPLE DAYS FRONT DOORS WERE TOTALLY INOPERABLE. COULD NOT OPEN FROM INSIDE OR OUT OF CAR. REQUIRED ENTRY FROM REAR SEAT. THEN UPON DRIVING TO DEALER FOR DIAGNOSIS THE DOOR AJAR LIGHT LIT UP AND RELEASED THE DOOR LATCHES SO THAT BOTH OF THE DOORS ATTEMPTED TO OPEN WHILE DRIVING AT HIGHWAY SPEED. THIS CONDITION HAPPENED TWICE. THIS ISSUE SEEMS TO DIRECTLY MIMIC MULTIPLE KNOWN ISSUES FOR FORD FLEX MODELS AND MANY OTHER FORD MODELS AROUND THIS SAME TIME. AT THIS TIME, 2015 FLEX MODELS ARE NOT INCLUDED (DESPITE THE OBVIOUS EXACT SAME CONDITION). I HAVE BEEN NOTIFIED BY MY LOCAL DEALER, FULTON FORD IN FULTON, MO THAT IT WILL COST ME NEARLY $1000 TO REPAIR BOTH FRONT DOORS THAT FAILED AT THE SAME TIME. REPAIR IS TO TAKE PLACE ON 01/30/20 (WAS DIAGNOSED ON 01/29/20). THEY HAVE CHECKED AND ACKNOWLEDGE THIS MIGHT BE A WIDER FORD ISSUE BUT OUR CAR SIMPLY DOESN'T HAVE A CURRENT RECALL SO NOTHING THEY CAN DO. SEEMS TOTALLY OUT OF PLACE SINCE THERE IS ENOUGH EVIDENCE THAT THIS IS AN ONGOING PROBLEM WITH FORD DOOR LATCHES.
