Open the full vehicle complaint log (all categories)THE LANE KEEPING DRIVING ASSISTANCE/DRIVING ASSISTANCE PRO ON THE 2020 BMW 840I GRAN COUPE PRODUCES A SUDDEN LOUD "BARK" WHEN THE ASSISTANCE SYSTEM LOSES SIGHT OF THE LANE MARKERS. THAT OFTEN HAPPENS IN INTERSECTIONS BUT CAN HAPPEN ANYWHERE WHERE THE LANE MARKERS ARE WORN. I BOUGHT THE CAR ON 2/29/2020 AND IT HAS HAPPENED MANY TIMES SINCE THEN AND NOT ONLY ON THE DATE SHOWN. THE SUDDEN LOUD "BARK" IS A DISTRACTION, A NUISANCE AND TOTALLY UNNECESSARY SINCE THE INSTRUMENT PANEL ALSO HAS A LARGE DISPLAY SHOWING THE STATUS OF THE DRIVING ASSISTANCE SYSTEM AND THE DRIVER IS SUPPOSED TO HAVE THE HANDS ON THE STEERING WHEEL ANYWAY. WHEN DRIVING A CAR, ANY DISTRACTION IS A TRAFFIC SAFETY ISSUE, MORE SO WHEN IT HAPPENS IN INTERSECTIONS. I HAVE TAKEN THE CAR TO THE BMW DEALER SHOP (WHERE I BOUGHT THE CAR) BUT THEY SAY THAT THE LOUD 'BARK' CANNOT BE TURNED OFF. MY REQUEST TO NHTSA IS TO DISALLOW BMW AND OTHER BRANDS TO USE SYSTEMS THAT PRODUCE SUDDEN DISTRACTING SOUNDS WHEN THE CAR IS IN MOTION. A LANE KEEPING ASSIST SHOULD BE A SYSTEM THAT IMPROVES TRAFFIC SAFETY AND NOT ONE THAT REDUCES IT DUE TO SUDDEN AND UNEXPECTED 'BARKS' THAT ARE MAJOR DISTRACTIONS.
