On 04-07-2021 I was traveling West on Florida S.R. 60 / US 301; WHEN A CAR IN FRONT OF ME WAS STOPPING. I APPLIED THE BRAKES AND FAILED TO STOP IN TIME; HITTING THE REAR END OF THE AUTO IN FRONT OF ME. IT APPEARS TO ME THAT THE BRAKES DID NOT WORK CORRECTLY TO STOP. I FEEL (FELT) LIKE THE BRAKE PEDAL WHEN APPLIED FELT LIKE AIR IN THE BRAKE LINE SYSTEM. THE BRAKE PETAL ALMOST WENT ALL THE WAY TO THE FLOOR. THEIR WAS ONLY ABOUT 3130 MILES ON THE VEHICLE AT THE TIME OF THIS INVIDENT. I STILL FEEL THAT THERE IS A PROBLEM WITH THE BRAKES AND HAD THEM CHECKED BY THE DEALER ON 08-20-2021 WHERE THEY PERFORMED A BRAKE INSPECTION AND THE PADS AND ROTOR WERE MEASURED. UPON THE FILING OF THIS REPORT I STILL DO NOT FEEL COMFORTABLE NOR SAFE DRIVING THIS VEHICLE WITH THE BRAKE ISSUE. ALSO MY FRONT DRIVER AIR BAG DID NOT DEPLOY. THE AUTO BODY MANAGER SAID WHEN I ASKED AS TO WHY; THAT THE SENSOR PERHAPS WAS NOT HIT STRAIGHT ON TO MAKE IT DEPLOY. I WILL FOLLW UP ON AN ADDITIONAL COMPLAINT ON THE AIR BAG ISSUE
