HELLO, ON AN ESTIMATED 8+ TIMES, I PUT MY VEHICLE INTO GEAR, DROVE OFF AND BOTH MY SIDE VIEW MIRRORS WERE IN THE CLOSED/UP POSITION. I HAVE LEARNED FROM GM SUPPORT THAT GM DID NOT DEVELOP SOFTWARE WHERE THE MIRRORS AUTOMATICALLY OPEN: WHEN EITHER OPENING THE DOORS OR PUTTING INTO GEAR. THIS IS EXTREMELY DANGEROUS AND I HAD NEVER EXPERIENCED ON MY FORMER MERCEDES E-350 LEASES, THIS SAFETY TECHNOLOGY WAS STANDARD. THE LATEST INCIDENT I WAS DRIVING ON A MAIN WEST TO EAST ROUTE FOR ABOUT 2 MILES, NEEDED TO GET INTO THE RIGHT LANE, WENT TO LOOK AT MY RIGHT MIRROR, AND IT WAS COMPLETELY FOLDED UP. IT WAS VERY, VERY DANGEROUS, ALMOST GOT ME REAR-ENDED SINCE I BRAKED HARD WHEN I NOTICED AND I ALMOST SIDE-SWIPED THE CAR TO MY RIGHT.
