I BOUGHT A CAR IN APRIL 2018. THE FIRST ACCIDENT OCCURRED ON THE HIGHWAY IN MAY 2018. I WAS DRIVING AT A SPEED OF 75 KM / H. I SAW THE CAR IN FRONT OF ME STEPPING ON THE BRAKES AND I ALSO STEPPED ON THE BRAKES, BUT MY CAR DID NOT SLOW DOWN. MERCEDES-BENZ KOREA CLAIMED THAT THERE WAS NO PROBLEM WITH THE CAR, ALTHOUGH THE CAR COLLIDED WITH THE CAR AS IT WAS. IN JULY 2018, THE SECOND ACCIDENT OCCURRED IN THE UNDERGROUND PARKING LOT OF THE APARTMENT WHERE I LIVE. I STARTED THE CAR, I SAW A CAR IN FRONT OF 60M.

FORTUNATELY, I DID NOT HIT THE CAR THAT WAS ON THE OPPOSITE SIDE, BUT MY CAR WAS PUSHED INTO THE WALL. ON CCTV, YOU CAN SEE THAT I WAS PUSHED INTO THE WALL WITH MY BRAKES ON.
