WHILE ADAPTIVE CRUISE CONTROL IS ENGAGED THE VEHICLE WILL BRAKE ON ITS OWN. THIS OCCURS WHEN THERE ARE NO OTHER VEHICLES OR OBJECTS IN SIGHT. THE VEHICLE APPLIES THE BRAKES HARD ENOUGH WHERE IF ANOTHER CAR IS FOLLOWING CLOSELY IT COULD REAR-END MY VEHICLE. I HAVE HAD THE CAR IN TO CIRCLE PORSCHE 5-6 TIMES WITH NO RESOLVE. THIS WAS FIRST REPORTED TO THE DEALER ON JUNE 29, 2015.
