NHTSA Complaint #11058332 — 2017 CHEVROLET VOLT

VEHICLE'S LANE DEPARTURE FUNCTION AND CALIBRATION WAS REPROGRAMMED AFTER A RECALL SERVICE AND NOT FUNCTION DOES NOT WORK. FUNCTION WAS NOT ONLY A PREMIUM CHARGE OPTION, BUT ORIGINALLY WOULD MONITOR THE LANE LINES AND ADJUST THE ELECTRONIC STEERING SYSTEM TO KEEP THE VEHICLE WELL WITHIN THE ROAD LANES' PAINTED LINES. NOW, THE VEHICLE WILL (MORE TIMES THAN NOT) COMPLETELY CROSS THE TIRES WELL OVER THE PAINTED LINE, TRAVELING SEVERAL TENS OF YARDS BEFORE ONLY SLIGHTLY CORRECTING ITS DIRECTION BACK TOWARDS THE LANE. IN A BEST CASE SCENARIO, VEHICLE SYSTEM WILL BEGIN CORRECTING ITSELF APPROXIMATELY JUST AS THE FRONT TIRE MAKES CONTACT WITH THE LANE BOUNDARY LINES. THIS HAS BEEN OBSERVED IN LANES OF VARYING WIDTH AND CONFIRMED BY THE SERVICING DEALERSHIP. FURTHER, SYSTEM IS INCONSISTENT IN ITS DETERMINATION AND "CORRECTION" LANE BOUNDARIES, SOMETIMES CROSSING THE LEFT LANE LINE ENTIRELY THEN BARELY TOUCHING THE RIDE SIDE LANE, OR VICE VERSA. SYSTEM HAS ALSO BEEN APPARENTLY LESS SENSITIVE IN READING THE LINES AS THE INSTRUMENT PANEL INDICATOR WILL NOT LIGHT UP INDICATING THAT IT RECOGNIZES LANES, EVEN THOUGH LANES ARE CLEARLY AND BRIGHTLY PAINTED AND ILLUMINATED BY EITHER HEADLIGHTS, STREET LIGHTS OR SUNLIGHT. AS THIS VEHICLE IS A COMPLETE DRIVE-BY-WIRE SYSTEM (BRAKES, STEERING, AND THROTTLE HAVE NO MECHANICAL CONNECTION TO DRIVER'S INPUTS), I HAVE SERIOUS CONCERNS WITH REGARDS TO THE SENSORS CAPABILITIES IN ACCIDENT AVOIDANCE AND FEEL THAT IN AN EMERGENCY SITUATION, THE SYSTEM WILL FAIL TO OPERATE AS PROMOTED AND PROMISED BY THE MANUFACTURE. THIS WOULD BE ACCEPTABLE IF THIS PERFORMANCE WAS SIMILAR OR CONSISTENT TO PERFORMANCE FROM INITIAL OPERATION, HOWEVER, THE OEM HAS EFFECTIVELY AND DRAMATICALLY CHANGING THE VEHICLE'S DRIVING DYNAMIC AND SAFETY FUNCTION THAT I (AND ANY REASONABLE DRIVER) HAVE BECOME COMFORTABLE WITH AS A DRIVER, WITHOUT MY CONSENT.
