2019 Kia K900 4 DR AWD

I BOUGHT THIS CAR IN NOV. '20. THE FIRST TIME THAT THE TEMP DROPPED BELOW 65, ON THE FIRST "AUTO STOP" OCCURENCE AFTER REACHING OPERATING TEMPERATURE, AFTER ABOUT A SECOND OF THE ENGINE TURNING OFF,A LOUD BEEP OCCURRED AND A MESSAGE POPPED UP SAYING THE SYSTEM HAS SHUT DOWN AND I NEEDED TO SHIFT INTO N OR P AND PRESS THE START BUTTON TO RESTART THE ENGINE. IT ACTUALLY REQUIRED PRESSING THE BUTTON TWICE WHILE THE LOUD BEEP CONTINUED, STUCK IN TRAFFIC. IT WILL DO THIS UP TO 4 TIMES IF IT'S BELOW ABOUT 65 AND THE VEHICLE HAS SAT FOR HOURS OUTSIDE.TO THIS DATE, THE MFG. HAS YET TO DETERMINE THE CAUSE OF THE SHUT DOWN. A DTC WAS NEVER STORED. A CONTINUOUS MIL ILLUMINATION NEVER HAPPENED. IT'S BEEN TO THE DEALER MULTIPLE TIMES. I CALLED KIA TWO DAYS AGO AND THEY SAID THEY WOULD CALL THE DEALER AND HAVE THEM PUT PRESSURE ON KIA'S OWN TECH LINE. NO CALL HAS BEEN RECEIVED.I BELIEVE THAT A LOSS OF MOTIVE POWER IN TRAFFIC REPRESENTS A SERIOUS SAFETY CONCERN AND REGARDLESS OF THE ACTUAL MALFUNCATION CAUSING THE SHUT DOWN, THE SHUT DOWN FAILURE MODE OF THE SYSTEM, VERSUS JUST RESTARTING THE ENGINE WITH A MIL ILLUMINATION AND A STORED DTC IS A SERIOUS SAFETY CONCERN AND THAT HYUNDAI MOTOR GROUP SHOULD BE MADE TO IDENTIFY ALL SUCH KIA, GENESIS, AND HYUNDAI MODELS WITH SUCH A SYSTEM AND BE MADE TO RECALL THEM AND REPROGRAM THEM TO NOT ALLOW A REMOVAL OF MOTIVE POWER WHILE BEING DRIVEN IN TRAFFIC, IN ADDITION TO ADDRESSING THE ACTUAL MALFUNCTION IN MY K900. OR IF THEY CAN'T, THEY NEED TO BE MADE TO DEACTIVATE THE SYSTEM PERMANENTLY, RESTATE FUEL ECONOMY ESTIMATES, AND REIMBURSE DRIVERS.
