NHTSA Complaint #10197400 — 2007 HONDA CIVIC

WHEN ENGINE IS WARM AND CAR IS AT IDLE (EITHER WHEN STOPPED AT TRAFFIC LIGHT OR WHEN PARKING BEFORE SHUTDOWN) AND YOU OPEN/CLOSE SUN ROOF AND/OR POWER WINDOWS THE RPMS DIP, CAR SHAKES, AND ENGINE ALMOST STALLS BEFORE RPMS RECOVER TO NORMAL IDLE. THIS HAS HAPPENED AT LEAST TWO DOZEN TIMES AND STARTED HAPPENING SOON AFTER TAKING DELIVERY. AT APPROX 400 MILES CAR WAS TAKEN INTO DEALER AND DEALER WAS ABLE TO REPRODUCE THE PROBLEM ON MY VEHICLE AND ALSO REPRODUCED THE PROBLEM ON OTHER NEW CIVICS ON DEALER LOT. DEALER RESET PCM AND PERFORMED IDLE RELEARN PROCEDURE. THIS DID NOT RESOLVE THE PROBLEM. DEALER REPORTED TO HONDA ENGINEERING AND THEY HAD NO KNOWLEDGE OF ISSUE AND OFFERED NO ADVICE. ADDITIONALLY AT APPROX 600 MILES AFTER CAR SAT UNUSED ALL DAY AND WHEN ATTEMPTING TO START LATER THAT NIGHT, THE CAR DID NOT START ON FIRST ATTEMPT. ON SECOND ATTEMPT AND AFTER CRANKING LONGER THAN USUAL FOR STARTUP, THE CAR STARTED ROUGHLY WITH A JOLT AND RAN ROUGH (CAR SHAKING) FOR 3-5 SECONDS. *TR
