2006 FORD FIVE HUNDRED. CONSUMER STATES UNEXPECTED VEHICLE MOVEMENT *TGW THE CONSUMER STATED IF THE VEHICLE WAS NOT IN PARK OR THE BRAKE WAS NOT APPLIED, IT WOULD MOVE. THE ENGINE WOULD SPIKE AS DISPLAYED BY THE TACHOMETER AND THE ENGINE COULD BE HEARD ACCELERATING. THE FIRST TIME THE VEHICLE WAS TAKEN TO THE DEALER, THEY WERE UNABLE TO DUPLICATE THE PROBLEM. THE SECOND TIME, THE VEHICLE WAS TAKEN TO THE DEALER, THEY DIAGNOSED THE PROBLEM AS A BAD ALTERNATOR. IT WAS SENDING BAD SIGNALS TO THE PCM CAUSING THE ENGINE TO SURGE. *JB.
2005
POWER TRAIN
NOT LONG AFTER PURCHASING MY VEHICLE MY HUSBAND AND I WERE DRIVING ON THE INTERSTATE WITH THE CRUISE CONTROL ON AND THE TRANSMISSION STOPPED WORKING. WE WERE ABLE TO PULL OFF SAFELY ONTO THE SHOULDER AND SHUT THE CAR OFF AND ONCE RESTARTED WAS FINE. WE HAVE SINCE STOPPED USING CRUISE CONTROL IN FEAR OF AN ACCIDENT. THE PROBLEM IS STILL THERE AND SEEMS TO BE GETTING WORSE. THE DASH WILL LIGHT CHECK TRANSMISSION, TRACTION CONTROL AND SOMETIMES CHECK ENGINE. ONCE THE CAR IS TURNED OFF AND BACK ON IT IS FINE FOR A WHILE, THE CHECK ENGINE LIGHT TAKES SOME TIME TO GO OFF. IT IS GETTING SO WE ARE AFRAID TO DRIVE IT, SOMETIMES IT DRIVES FINE AND OTHERS THE TRANSMISSION QUITS. THE OTHER DAY I WENT TO PASS A CAR AND THE LIGHTS CAME ON AS I HAD MOVED INTO THE LANE TO PASS ON THE INTERSTATE. ONCE I WAS IN MY LANE AGAIN A FEW MINUTES LATER IT DOES IT AGAIN AND THIS TIME A BIG MAC TRUCK IS COMING UP ON ME. I HAVE READ OF SEVERAL PROBLEMS OF THIS WITH THIS SAME CAR AND IT HAS BEEN SAID THERE IS A PROBLEM WITH THE THROTTLE BODY AND/OR ELECTRICAL SYSTEM. THIS IS VERY DANGEROUS AND FORD SHOULD BE ISSUING A RECALL TO FIX THE PROBLEM BEFORE SOMEONE IS INJURED OR KILLED. *TR
