ON 7/25/2020, MY 2019 KIA SORENTO HAD COMPLETE BRAKE FAILURE, FOR THE THIRD TIME IN 4 MONTHS. I TOOK MY SORENTO TO MY DEALERSHIP SERVICE DEPARTMENT WHERE I WAS TOLD THAT THE PROBLEM WAS A "DEFORMED BOOSTER BRAKES VACUUM HOSE"WHICH THEY REPLACED (2 DAYS IN THE SHOP MARCH 23RD TOO MUCH 25TH). ON JULY 13, 2020 IT HAPPENED AGAIN AND THE CAR WAS BACK AT THE DEALERSHIP SERVICE DEPARTMENT, FOR THE SECOND TIME. A WEEK LATER(JULY 25TH) THEY CALL TO ME TO PICK UP THE CAR. THE SERVICE MANAGER INFORMED ME THAT THEY HAD REPLACE THE HOST WITH AN UPDATED VACUUM HOSE, AND THAT KIA COOPERATION ENGINEERS WERE AWARE OF THIS PROBLEM. ON SATURDAY 5 DAYS AFTER HAVING THE VEHICLE BACK FROM THE SERVICE DEPARTMENT, THE BRAKES FAILED AGAIN COMPLETELY WHILE I WAS DRIVING, WHICH RESULTED IN A ACCIDENT. MY INSURANCE COMPANY IS CALLING IT A TOTAL LOST. MY CAR IS A LEASE WITH 9,800 MILES ONLY.I HAVE HAD THE CAR FOR 1 YEAR ONLY. MY WAS NOT THE ONLY KIA SORENTO BROUGHT BACK TO THE DEALERSHIP WITH THE SAME PROBLEM. WHAT SHOULD I DO?
