NHTSA Complaint #10786587 — 2015 HONDA CIVIC

NOTICED A SHUDDER WITH VEHICLE DURING 1ST WEEK OF PURCHASE. THOUGHT IT WAS A LITTLE WEIRD SINCE BEING A NEW CAR. ASSUMED THAT IT WAS AN ISOLATED INCIDENT WITH REGARDS TO BREAK IN OF VEHICLE. 2ND WEEK OF OWNERSHIP ON MY WAY TO WORK, NOTICED THE SHUDDER MULTIPLE TIMES DURING STOP AND GO TRAFFIC. THIS SHUDDER LATER TRANSITIONED INTO A KNOCK OR PINGING OF SOME SORT WHILE JERKING AND ACCELERATING ON ITS OWN WITHOUT ANY DRIVER INPUT. VERY SCARY AT THIS POINT...GOT OFF THE FREEWAY AND PARKED THEN TURNED THE VEHICLE OFF. UPON START UP, VEHICLE STILL IDLING VIOLENTLY. HAD TO GET TO WORK SO JUST BRAKED MOST OF THE WAY AND DROVE WITH ADDED CAUTION. AFTER WORK, CAR BEHAVED NORMALLY ON MY WAY HOME WITH ECON AND AIR CON BOTH OFF. SHUDDER IS STILL PRESENT TO THIS DAY DURING LIGHT TO MODERATE ACCELERATION AT 30 - 40 MPH. I AM FEARFUL OF USING THE ECON AND AIR CON TOGETHER AS THIS WORSENS THE PROBLEM. HONDA AND THE PUBLIC NEEDS TO KNOW ABOUT THIS.
