CAR DOORS UNLATCHED (BECOMING IN OPEN POSITION [UNLOCKED AND UNLATCHED] BEFORE IT BEING COMPLETELY OPEN). IT HAPPENED TWICE, ONES WHEN I WAS DRIVING AND THE WARNING BUZZER TURNED ON AND THE INSTRUMENT PANEL GIVE ME A MESSAGE TELLING ME THE DRIVING DOOR IS OPEN, THIS IS HAPPENED SUDDENLY AFTER DRIVING FOR 10 MINUTES IN VERY GOOD LOCAL STREETS CONDITION. I STOPPED TO CHECK THE DOOR AND I WAS SURPRISED TO FIND ITS BEEN UNLATCHED TO THE PRE OPEN POSITION. SECOND TIME HAPPENED WHEN WAS THE CAR PARKED AND LOOKED, AFTER ABOUT 30 MINUTES THE CAR HORN STARTS BEEPING AND THE LIGHTS FLASHING, L GOT A MESSAGE FROM ONSTAR ON MY PHONE TELLING ME MY CAR DOORS ARE IN OPEN POSITION. I WENT OUT TO CHECK THE CAR AND I FOUND THE DRIVER SIDE REAR DOOR IS IN OPEN POSITION (PRE OPEN POSITION, UNLOCKED AND UNLATCHED POSITION, IF YOU PULL THE DOOR IT WILL OPEN COMPLETELY). THIS IS A SAFETY CONCERN
