NHTSA Complaint #10926597 — 2017 FREIGHTLINER CASCADIA

THIS COMPLAINT PERTAINS TO ADAPTIVE CRUISE CONTROL (ACC), FORWARD CRASH AVOIDANCE (FCA) AND LANE DEPARTURE WARNING SYSTEMS (LDWS). I HAVE BEEN DRIVING THIS SPECIFIC VEHICLE BUT IT WILL PERTAIN TO ALL VEHICLES WITH THESE SYSTEMS. THE ACC AND FCAS BECAUSE OF ITS STRAIGHT LINE OF SIGHT IS MISINTERPRETING THE DATA ON APPROACH TO BRIDGES, OVERPASSES AND OVERHEAD SIGNS AND WILL INITIATE A HARD BRAKING EVENT ON THE INTERSTATE WHEN NO BRAKING IS REQUIRED CAUSING THE POTENTIAL TO LOSE CONTROL AND FOR A FOLLOWING VEHICLE TO CRASH. THIS PROBLEM WOULD BE INTENSIFIED ON WET, ICY AND SNOW COVERED ROADS. I HAVE ALSO EXPERIENCED A HARD BRAKING EVENT ON INTERSTATES ON APPROACH TO A CURVE IN THE ROAD WHERE VEHICLES AHEAD WILL ALREADY BE IN THE CURVE IN ANOTHER LANE AND THE DATA IS MISINTERPRETED AS A CRASH AND BRAKES HARD BECAUSE THE OTHER VEHICLES ARE DIRECTLY IN THE LINE OF SIGHT. AGAIN, NO BRAKING WAS REQUIRED. ON APPROACH TO A VEHICLE ON THE HIGHWAY READY TO MOVE INTO ANOTHER LANE TO EXECUTE A PASSING MANEUVER THE VEHICLE IS BRAKED FORCING A LOSS IN VEHICLE MOMENTUM WHEN NO BRAKING WAS REQUIRED. IN INCLEMENT WEATHER, RAIN, SNOW, FROST AND FOG THE SENSORS BECOME UNABLE TO SEE WHICH IS THE BEST THING THAT COULD HAPPEN AND THE ONLY WAY TO DISABLE IT THAT I KNOW OF. THESE EVENTS OCCUR EVERY SINGLE DAY ON MY TRIPS. I AM A PROFESSIONAL DRIVER WITH 35 YEARS' EXPERIENCE IN COMMERCIAL VEHICLES AND 40 IN A CAR. I DRIVE 570 MILES A NIGHT. THESE TECHNOLOGIES IN THEIR CURRENT STATE HAVE NO PLACE IN VEHICLES ON THE PUBLIC HIGHWAY SYSTEMS. WITH WINTER COMING I AM VERY CONCERNED FOR MY SAFETY AND THAT OF THE MOTORING PUBLIC AND WANT A RECORD OF MY COMPLAINT ON FILE. TRUCK IS EQUIPPED WITH THE DETROIT ASSURANCE 2.0 SYSTEM.
