NHTSA Complaint #10412969 — 2006 FORD FIVE HUNDRED

WHILE RUNNING THE AIR CONDITIONER, THEN EITHER BRIEFLY SHUTTING OFF ENGINE OR IDLING IN PARK OR NEUTRAL, ONCE THE CAR IS SHIFTED INTO DRIVE GEAR THE ENGINE ACCELERATES ON ITS OWN, FOOT BREAK IS ON. RPMS INCREASE FOR 3-4 SECONDS THEN GO BACK DOWN TO NORMAL. THE CAR WAS UNABLE TO LURCH FORWARD ONLY BECAUSE I'VE HAD MY FOOT ON THE BREAK DUE TO MY SHIFTING OF GEARS (FROM PARK OR NEUTRAL TO DRIVE). THE FIRST TIME THIS HAPPENED I ONLY HAD THE BREAK PEDAL SLIGHTLY DEPRESSED - CAR JUMPED FORWARD - I FULLY DEPRESSED BRAKE PEDAL TO STOP. OCCURS INTERMITTENTLY BUT INTENSITY OF SURGE INCREASING. YESTERDAY HAD A MUCH STRONGER SURGE IN DRIVE-THRU, THEN CAR STALLED. WAS ABLE TO RESTART, ENGINE LIGHT HAS REMAINED ON SINCE YESTERDAY'S INCIDENT. TOP MOTOR MOUNT DAMPER (ROUND RUBBER DISK) IS CRACKED THRU AS WELL, PROBABLY DUE TO LURCHING.
