NHTSA Complaint #10692049 — 2010 HONDA INSIGHT

UNEXPECTED ACCELERATION WHEN BRAKING, THIS IS A RECURRING PROBLEM. I WAS DRIVING ABOUT THE SPEED LIMIT ON SECONDARY ROADS ~40 MPH NO TRAFFIC AND THE ROADS WERE CLEAR OF ICE AND SNOW AND THE ENGINE WAS WARM, THE INSTRUMENT PANEL INDICATOR FOR COLD ENGINE HAD EXTINGUISHED. I APPROACHED A RED STREET LIGHT I PRESS THE BRAKE PEDAL LIGHTLY, THERE WERE NO CARS IN FRONT OF ME (FOOT CLEARLY NOT ON THE GAS PEDAL) I EXPECTED THE CAR COME TO A LEISURELY STOP BY COASTING WITH LITTLE BRAKING HELP. THE BRAKE PEDAL FELT STIFF, RESISTED THE PRESSING OF THE FOOT. THE ENGINE BEGAN TO REV UP AND I ALSO NOTED THE BATTERY IMA CHARGE/ASSIST GAUGE WENT HIGHER INTO THE BLUE (IMA ASSIST). I APPLIED MORE PRESSURE TO THE BRAKE PEDAL THE ENGINE ACCELERATED MORE AND ASSIST GAUGE INCREASED FURTHER INTO THE BLUE AREA. I REPEAT: THE BRAKE PEDAL FEELS HARD LIKE PUTTING YOUR FOOT ON A ROCK, NO GIVE. I NOW KNOW THIS IS THE FIRST SIGN THERE IS GOING TO BE A BRAKING ISSUE. IT HAPPENED EVERY TIME THE PROBLEM OCCURS! BUT THE PROBLEM DID NOT OCCUR EVERY TIME I STOPPED ON THIS TRIP. WHEN I BRAKE AND THE CAR AND THE CAR GOES INTO AUTO-STOP MODE THERE IS NO ISSUE. WHEN THE UNEXPECTED ACCELERATION OCCURS I CAN SHIFT THE CAR OUT OF DRIVE (D) AND INTO NEUTRAL (N) THE ENGINE WILL MOMENTARILY RACE, EXCEEDING 5000 RPM, ALMOST RED LINING, AND THEN RETURN TO A NORMAL IDLE. IT SHOULD BE NOTED THAT THE PROBLEM PERSISTED THOUGHT THE TRIP WITH THE CAR BEING SHUT OFF AND PARKED FOR A SHORT TIME (2 OCCURRENCES) RESTARTED AND DRIVEN AGAIN. ONLY WHEN THE CAR WAS LEFT FOR HOURS INCLUDING OVERNIGHT DID THE PROBLEM GO AWAY, MY GUESS IS 19 HOURS. *TR
