Open the full vehicle complaint log (all categories)THE ADAPTIVE CRUISE CONTROL HAS BEEN MALFUNCTION SINCE I BOUGHT THE CAR. IT'S BEEN IN THE SHOP THREE OR MORE TIMES FOR IT. 2 DAY AGO I RECORD ON MY IPHONE AS THE CAR STARTED SLOWING DOWN DUE TO A STOPPED CAR AHEAD OF ME AND THEN SUDDENLY STARTED SPEEDING UP WHILE THE CAR IN FROM WAS STILL STOPPED DUE TO A RED LIGHT. I DON'T HAVE PICTURES BUT I DO HAVE A SMALL VIDEO. PLEASE LET ME KNOW IF I CAN UPLOAD THAT SOMEWHERE FOR YOU TO VIEW. ALSO MY RADIO RESET TO ALL THE DEFAULT STATION WHEN I TURN THE CAR OFF. THE DEALER REPLACE THE SENSOR OR CAMERA THAT TRACKS THE ACC, BUT I'M STILL HAVE THE TROUBLE. ON THE SAME DAY I WAS DRIVING IN MY NEIGHBORHOOD AND I SET MY ACC TO 35. I AIMED THE CAR TOWARDS A PARKED CAR, AND THE ACC DID NOT SLOW DOWN THE CAR, DID NOT FLASH THE BRAKE ALARM, OR DID ANYTHING. I HAD TO SWERVE TO AVOID A SWERVE TO AVOID A COLLISION. AGAIN I HAVE THE VIDEOS.
