Open the full vehicle complaint log (all categories)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. AS SOON AS I FOUND THE CAR AND STEPPED ON THE BRAKES, MY CAR SUDDENLY STARTED TO RUN AT HIGH SPEED. I WAS SURPRISED AND BRAKED HARDER. THE HARDER THE BRAKES WERE, THE FASTER THE CAR DROVE. 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. IT IS BECAUSE THE BRAKE LIGHT OF MY VEHICLE COMES IN. BY THE WAY, MERCEDES-BENZ KOREA SAYS THAT THERE IS NO PROBLEM WITH MY VEHICLE FOR FIVE MONTHS AND THAT EVERYTHING IS MY FAULT. I HAVE ALSO REPORTED SEVERAL TIMES THAT THERE IS A PROBLEM WITH THE ABS MODULATOR OF A C-CLASS CAR MADE BY MERCEDES-BENZ AT A KOREAN BROADCASTING STATION. MERCEDES-BENZ KOREA TOLD ME THAT WHEN I FIRST HAD A CONVERSATION, THE ABS MODULATOR WAS WORKING AND THAT THE CAR SLIPPED BECAUSE OF IT. I ACCIDENTALLY HIT THE BRAKE PEDAL. MY CAR WAS TURNING ON THE BRAKE LIGHTS ALL THE WAY UP TO 60M STRAIGHT AHEAD (I WAS STILL ON THE BRAKES) AND THE CAR EVENTUALLY HIT THE WALL. WHEN I PROTESTED TO MERCEDES-BENZ KOREA, THEY SAID TO ME, "THE BRAKE LIGHT IS ON, BUT THE BRAKE ASSIST LIGHT IS OFF. YOU DID NOT BRAKE." THEY HAD AN OBVIOUSLY DIFFERENT ANSWER FROM THE BEGINNING. "I RIDE THE CAR AGAIN. HOW WILL YOU BE RESPONSIBLE IF YOU HAVE AN ACCIDENT?" WHEN ASKED THEM, THEY "DO NOT HAVE TO ANSWER ANYTHING THAT HAS NOT HAPPENED YET."
