NHTSA Complaint #10438815 — 2012 HONDA ACCORD

INCIDENT DATE: 12/05/2011, 5:45PM WEATHER/ROAD CONDITION: GOOD, NO RAIN/SNOW, NORMAL TRAFFIC PATTERN SUMMARY: ACCORD 2012 LX HAD A SUDDEN ENGINE REV FOR ABOUT A COUPLE OF SECONDS AND WENT BACK TO NORMAL WITHOUT DRIVER INTERVENTION. MINOR GAS PEDAL VIBRATION NOTICED FOR FIRST 500 MILES DURING BREAK-IN. DETAILS: I WAS DRIVING ACCORD 2012 LX ON A LOCAL MAIN STREET AT ABOUT 20 TO 25 MPH, ENTERING A NORMAL SMALL SLOPE. I SUDDENLY HEARD LOUDER ENGINE NOISE, AND NOTICED TACHOMETER GOING UP FROM BELOW 2K TO 3K RPM QUICKLY. AT THE SAME TIME, I FELT GAS PEDAL WAS MOVING AWAY FROM MY RIGHT FOOT. EVENTUALLY THE GAS PEDAL CAME BACK AND TACHOMETER READING WENT BACK TO NORMAL AS WELL. THIS LASTED FOR A COUPLE OF SECONDS. I DID NOT MOVE MY RIGHT FOOT AWAY FROM GAS PEDAL AND DID NOT INTERVENE WHILE THIS WAS HAPPENING. SINCE THIS SUDDEN ENGINE REV WENT AWAY IN A COUPLE OF SECONDS BY ITSELF, I DIDN'T FEEL THAT THE ACCORD ACCELERATED A LOT DURING THE PERIOD. DURING FIRST 500 MILES ON THE ACCORD, I ALSO FELT MINOR GAS PEDAL VIBRATION FREQUENTLY ON ROADS THAT ARE NOT PERFECTLY PAVED AND HAVE SOME MINOR BUMPS. I HAVE NEVER NOTICED ANY SUCH GAS PEDAL VIBRATION ON OTHER CARS WHEN DRIVING DOWN ON THE SAME ROADS. THE VIBRATION BECAME LESS PRONOUNCED AFTER 500 MILES, AND I DIDN'T NOTICE IT LATELY. I AM NOT SURE IF THERE IS ANY RELATIONSHIP BETWEEN INITIAL GAS PEDAL VIBRATION DURING BREAK-IN AND RECENT ENGINE REV INCIDENT. I AM CONCERNED ABOUT HIGHWAY SAFETY OF THE CAR. *TR
