NHTSA Complaint #11101468 — 2017 ACURA MDX

MULTIPLE ERRORS IN SAFETY WARNING AND ACTION SYSTEMS SUCH AS THE COLLISION MITIGATION AND WARNING SYSTEM. FOR EXAMPLE, WHILE DRIVING ON A FOUR LANE HIGHWAY (UNDIVIDED, NO HEAD-ON TRAFFIC), MY VEHICLE WAS IN THE FAR-RIGHT LANE, 800-900 FEET BEHIND A TRUCK IN THE LEFT LANE. THE TRUCK BEGAN SLOWING AND MOVED INTO THE WIDE LEFT-HAND TURN LANE LEADING TO A SIGNAL CONTROLLED BY A TRAFFIC SIGNAL. WHEN I WAS ABOUT 2-300 FEET BEHIND THE TRUCK, NOW STOPPED (AWAITING A LEFT-TURN LIGHT), THE COLLISION MITIGATION SYSTEM FLASHED THE WORD 'BRAKE' IN THE HEADS-UP DISPLAY AND WENT INTO FULL BRAKING MODE TO THE LIMIT OF THE ANTI-SKID SYSTEM. THERE WAS NO OTHER TRAFFIC ON THE ROAD WITHIN 3-3500 FEET OF THE INTERSECTION. THIS HAS HAPPENED NUMEROUS TIMES WHERE THE COLLISION MITIGATION SYSTEM WENT TO FULL BRAKING WITH NO OTHER VEHICLES POSSIBLY REPRESENTING A DANGER. NUMEROUS OTHER WARNINGS OF THE SENSORS ALERT AT RANDOM. MOST RECENTLY, WHILE STOPPED AT AN INTERSECTION WITH MY FOOT ON THE BRAKE ' THE ENGINE IDLE-STOP SYSTEM WORKING (I.E., THE ENGINE WAS NOT OPERATING) ' WE RECEIVED A WARNING TO 'BRAKE' AND WARNING OF APPROACHING VEHICLES (WHICH SHOULD NOT HAPPEN). WE FREQUENTLY GET WARNINGS OF NON-EXISTENT TRAFFFIC APPROACHING FROM BEHIND WHILE SITTING IN A PARKING SLOT, TRANSMISSION IN PARK, PARKING BRAKE ON (OR OFF, BOTH). CRUISE CONTROL WAS NOT USED IN ANY OF THESE CASES. THERE ARE DOZENS OF OTHER FALSE WARNINGS, BOTH AUDIO AND VISUAL, THAT DO LITTLE MORE THAN TO TRAIN US TO IGNORE THEM, NOT A GOOD ATTRIBUTE OF ANY WARNING SYSTEM. BACKUP COLLISION SENSORS FREQUENTLY ALERT TO HAZARDS WHICH CANNOT BE SEEN: I'VE ACTUALLY SHUT DOWN THE ENGINE, GET OUT AND LOOKED TO SEE IF SOMETHING LIKE A SHOPPING CART MIGHT HAVE ROLLED INTO THE VEHICLE'S PATH, ONLY TO FIND NOTHING WHATSOEVER BEHIND THE VEHICLE. WARNINGS ARE BOTH IN VISUAL (WORD/GRAPHICS) AND AUDIO FORM.
