“The contact's fiancée owns a 2005 Mercury Monterey. The contact stated while his fiancée was driving at an undisclosed speed, the accelerator pedal was depressed and the vehicle failed to respond and inadvertently stopped. The contact’s fiancée pushed the vehicle over the third of a mile by herself until she received assistance to push the vehicle to a parking lot. The vehicle was hauled to the contact's residence. The contact stated that upon starting the vehicle and shifting into gear, the vehicle failed to respond. The contact, who is an independent mechanic diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 95,357.”

“IT WAS RAINING AND MY VEHICLE KEPT GOING INTO NEUTRAL AND STALLING. I'D PRESS THE GAS, NOTHING WOULD HAPPEN. IT WOULDN'T GO INTO REVERSE. WHEN I PUT IT IN NEUTRAL THE ENGINE JUST REVVED UP. PUTTING IT PARK WAS OK. CHECK ENGINE CODES P0715 AND P0340 APPEARED. A FLASHING CHECK ENGINE LIGHT (!), AND SOLID CHECK ENGINE LIGHT APPEARED. PUTTING IN DRIVE, IT WOULD ONLY GO INTO 3RD GEAR. 1ST GEAR WORKED IF I MOVED THE PRNDL TO 1. REVERSE DIDN'T WORK AT ALL. I COULD HAVE EASILY BEEN KILLED IF THIS HAPPENED WHILE DRIVING ANYWHERE BUT MY NEIGHBORHOOD. THIS IS DIFFERENT FROM THE RECENT TORQUE CONVERTER RECALL THAT IS ALSO SCARY AND ALSO RESULTS IN LOSS OF FORWARD MOMENTUM. MY PROBLEM IS WITH THE PCM. THE DEALER PERFORMED DIAGNOSTICS AND REPAIRS ACCORDING TO FORD'S TSB 06-14-10 WHICH INDICATES THIS IS A COMMON PROBLEM ON ALL 1999-2007 FORD VANS. IF THEY'VE KNOWN ABOUT THIS FOR 7 YEARS, AND IT AFFECTS NEARLY A MILLION VEHICLES, WHY HASN'T IT BEEN RECALLED? SURELY NHTSA HAS RECEIVED COMPLAINTS ABOUT THIS. I HAVE A FRIEND WHO HAD THIS HAPPEN ON HER 2004 FORD VAN WITHIN THE LAST YEAR. SHE ALSO LOST REVERSE AND THE CAR WOULD LIMP IN DRIVE JUST LIKE MINE DID. THE REPAIR SHOP KNEW…”
