2018 Subaru Outback

REAR TAIL GATE OPENS WITHOUT ACTIVATION AT 35 MPH WHILE VEHICLE IS IN MOTION. I HAVE A VIDEO BUT IT IS TOO BIG TO SEND. MY WIFE AND I WERE ON A BUSY HIGHWAY AFTER JUST PURCHASING FLOWERS AND PLANTS AT A LOCAL NURSERY WHEN THE TAILGATE JUST STARTED TO OPEN ALL BY ITSELF SPILLING SOME OF THE PLANTS ON THE HIGHWAY. THE TAILGATE LOCKED IN THE OPEN POSITION AT ABOUT TWO FEET IN THE OPEN POSITION.

8" NAVIGATION/DISPLAY FROZEN. NO BACK-UP CAMERA WHEN IN REVERSE. DOES NOT RESPOND TO INPUTS EITHER ON THE DISPLAY OR FROM STEERING WHEEL. "POWER" SWITCH DID NOT POWER DOWN THE UNIT. STOPPING THE ENGINE AND RESTARTING DID NOT RESET THE UNIT. STOPPING THE ENGINE, OPEN AND CLOSE THE DRIVERS DOOR AND RESTARTING DID NOT RESET THE UNIT. REMAINED INOPERATIVE DURING MORNING COMMUTE (30 MIN). CENTER CONSOLE REMAINED ON AFTER EXITING AND LOCKING THE CAR. AFTER 9 HOURS THE BATTERY WAS DRAINED AND THE ENGINE WOULD NOT START. AFTER A JUMP-START, THE UNIT DID RESET AND SEEMS TO BE WORKING NORMALLY. THERE SHOULD BE A WAY TO POWER-DOWN (REBOOT) THE NAVIGATION/RADIO DISPLAY WITHOUT HAVING TO STOP THE CAR AND RESTART THE ENGINE.

AFTER PUTTING ON HAZARD SWITCH AND LEAVING VEHICLE, I CAME BACK TO VEHICLE AND THE KEYLESS ENTRY WOULD NOT FUNCTION. SYSTEM DID NOT SEEM TO RECOGNIZE MY SMARTKEY AS THE DOOR HANDLE SENSOR DID NOT OPERATE. I TRIED THE BUTTONS ON THE SMARTLY FOB AND THEY TOO DID NOT FUNCTION. ALSO TRIED THE MOBILE REMOTE APP AND THAT TOO FAILED. I HAD TO USE THE MECHANICAL KEY TO ENTER VEHICLE. OF COURSE THE SECURITY HORN GOES OFF, BUT STRANGELY I WAS ABLE TO START VEHICLE SO SYSTEM WAS ABLE TO RECOGNIZE MY SMARTKEY AFTER ENTRY. PROBLEM SEEMS TO ONLY OCCUR AFTER A SPECIFIC TIME PERIOD. IF I PUT ON THE HAZARDS AND COME BACK IN A COUPLE MINUTES, SYSTEM WORKS NORMALLY. IT SEEMS TO OCCUR AROUND THE FIVE TO 10 MINUTE TIME FRAME.

THE CAR IS PARKED. THE FLASHERS ARE ACTIVATED. THE CAR IS THEN LOCKED FROM THE OUTSIDE WITH THE KEY FOB. AFTER RETURNING TO THE CAR A SHORT TIME LATER (MAYBE 5 MINUTES OR SO) THE KEY FOB IS TOTALLY UNUSABLE. LOCK, UNLOCK, REAR HATCH OR PANIC DO NOT WORK. MUST THEN USE THE KEY IN THE DOOR LOCK, TO UNLOCK THE DOOR. THEN, OF COURSE, THE ALARM SOUNDS UNTIL YOU CAN PUT THE KEY INTO THE IGNITION TO SILENCE THE ALARM. THERE APPEARS TO BE A TIME OUT PROBLEM BECAUSE THE KEY FOB CAN UNLOCK THE CAR WITH THE HAZARD FLASHERS ON, RIGHT AFTER LOCKING THE CAR BUT THIS PROBLEM ONLY HAPPENS AFTER THE CAR HAS BEEN LEFT FOR A SHORT TIME. I HAVE GIVEN THIS PROBLEM TO SUBARU HEADQUARTERS AND THEY GAVE ME A CASE NUMBER OF 1-27586772057. IN AN EMERGENCY WHEN THE FLASHERS ARE ACTIVATED, IF THE CAR IS LOCKED AND UPON RETURNING A SHORT TIME LATER AND THE KEY FOB WON'T UNLOCK THE CAR, THERE COULD BE A DANGEROUS SITUATION, ESPECIALLY IN A DANGEROUS LOCATION OR SOMEONE (ESPECIALLY AN OLDER PERSON) MIGHT PANIC AND NOT THINK CLEARLY WHAT TO DO NEXT. I AM ABLE TO REPEAT THIS PROBLEM AT ANY TIME SINCE IT HAPPENED. I TRIED BOTH KEY FOBS WITH THE SAME RESULT.
