I OWN A 6 SPEED MANUAL SPORT COUPE PURCHASED ON 5/30/19. ON 2/10/20 I WAS STOPPED AT A LIGHT ON A SLIGHT DOWNHILL 15- 20' BEHIND CAR IN FRONT. SHIFT WAS IN NEUTRAL WITH MY FOOT ON BRAKE PEDAL. AFTER A WHILE, MY CAR STARTED MOVING FORWARD. I PUSHED HARDER ON THE BRAKE PEDEAL BUT NO RESPONSE AND COASTED INTO REAR OF CAR. ONE PERSON IN EACH CAR AND NOBODY INJURED. FEARFUL THAT BRAKE FAILURE WOULD OCCUR AGAIN, HAD CAR TOWED TO LOCAL HONDA DEALER WHERE PURCHASED. RECEIPT TO ME INDICTED THEY DID DIAGNOSTIC TESTING, INSPECTED BRAKE SYSTEM AND TEST DROVE CAR. "ADVISED CUSTOMER NO PROBLEMS AT THE MOMENT". AS NOTED BEFORE TESTING, SINCE NO MANUFACTURER DEFECTS FOUND WAS CHARGED $139.95. ON 2/11, RECEIVED CALL FROM MGR. OF HONDA SVC. DEPT. DUE TO MY NEGATIVE SURVEY RESPONSES. TOLD HIM I WAS NOT SATISFIED WITH ANSWER BY EMPLOYEE TO MY QUESTION OF WHY FORWARD COLLISION MITIGATION/FCM DID NOT BRAKE WHEN GETTING CLOSE TO CAR. MGR. STATED THAT FCM IS DESIGNED NOT TO WORK WHEN CAR IN NEUTRAL OR REVERSE. I CONSIDER LACK OF FCM IN NEUTRAL TO BE A SERIOUS SAFETY DESIGN FLAW. MGR. THEN RECOMMENDED THAT I OPEN CASE WITH HONDA CUSTOMER RELATIONS WHICH DONE ON 2/14. REP. TOOK DOWN MY INFO. AND ASKED WHAT I WANTED FROM HONDA. I SAID THEY NEED TO DETERMINE WHY THE BRAKE FAILURE HAPPENED AND WHAT CAN BE DONE SO I HAVE CONFIDENCE THAT IT WILL NEVER OCCUR AGAIN. SHE THEN GAVE ME A CASE # AND STATED THAT IT WOULD NEED TO BE REFERRED TO THE "LEVEL 1" DEPT. HANDLING ACCIDENTS/INJURIES/FATALITIES.
