2020 Kia Optima Brakes

FOR THE PAST FEW DAYS I HAVE BEEN FEELING A LEFT TO RIGHT MOVEMENT AT TIMES WHEN I PRESS THE BRAKE PEDAL SO AFTER FURTHER CHECKING I NOTICED IT MOVES LEFT TO RIGHT WHEN MOVED BY HAND MY CAR ONLY HAS 36128 MILES SO WHY IS THIS COMING LOOSE ALREADY?

THE FCW FORWARD COLLISION WARNING SYSTEM SEEMS TO NOT GET ACTIVATED UNDER ANY CIRCUSNSTANCES. I HAVE CHANGED THE SENSITIVITY OF THE SYSTEM TO ALL LEVELS AND IT NEVER SEEMS TO DETECT THE CAR IN FRONT OF IT. IT NEVER WARNS YOU OF AN INMINENT COLLISION. THE CAR IS ALWAYS IN MOTION WHEN I TRIED THE SYSTEM

I OWN A 2020 KIA OPTIMA (MY SECOND ONE IN LESS THAN A YEAR). THREE WEEKS AGO, I APPLIED MY BRAKES BEFORE ENTERING A CURVE. IN THE PROCESS, I HIT A BUMP (NOT A POT HOLE) IN THE ROAD'S AND MY BRAKES DISENGAGED AND I THOUGHT I WOULD LOSE CONTROL OF THE VEHICLE BECAUSE I WAS NOT SURE THE BRAKE WERE GOING TO ENGAGE IN TIME FOR ME MISS A HIT ON COLLUSION. THE SAME THING HAPPEN AGAIN, YESTERDAY. THIS IS NOT THE FIRST TIME I HAVE EXPERIENCED BRAKE PROBLEMS WITH A KIA OPTIMA. IN MY 2016, THE SAME THING WAS OCCURRING. THE SERVICE SHOP REPLACE A ROD OR SOMETHING THE BRAKING SYSTEM. I HAD A LOANER KIA OPTIMA (2019). I COULD FEEL VIBRATIONS IN BRAKE PADDLE WHEN I DROVE OVER A BUMP IN THE ROAD WHILE APPLYING THE BRAKES. THE SAME OCCURRED IN THE FIRST 2020 KIA OPTIMA THAT I PURCHASED LAST OCTOBER. KIA COUNTRY SAVANNAH TRY EVERYTHING TO SOLVE THE PROBLEM. LUCKILY, THE DEALERSHIP TRADED ME I OUT OF THAT VEHICLE BEFORE MY FIRST PAYMENT AND WAS GIVEN A LOANER VEHICLE UNTIL MY CURRENT VEHICLE WAS LOCATED AND DELIVERED FROM ANOTHER DEALERSHIP. NOW, I EXPERIENCING THIS ISSUE WITH YOUR COMPANY'S VEHICLE. I WAS FORCED TO TRADE-OUT OF 2016 CAR DUE TO KNOWN ENGINE PROBLEMS.
