Five Hundred 6-cyl

  • 83,000 miles


The contact owns a 2005 Ford Five hundred ltd. The contact stated that while driving 20 mph, the vehicle started to lunge forward and backward before stalling. The contact merged the vehicle to the shoulder, turned the engine on and off and the vehicle started immediately. The fail safe mode warning light started to illuminate. The dealer was notified of the issue but the vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 83,000. The consumer stated before she started driving on the road, she backed out of a parking space. She had her foot on the brake slightly as she was backing up, when the vehicle tried to lunge forward then backward. She applied the brake all the way, stopped the vehicle, but did not turn it off and the fail safe mode warning light illuminated. She tried to back up again, but it still wasn't running correctly, but she managed to finish backing out and straightened out the vehicle. The fail safe mode light stayed on. She sat for a minute and began to exit the parking lot. She only drove 500 feet, when the incident happened again. Updated 10/01/12

Vehicle shifts hard when hitting passing gear on highway like transmission is slipping or going out. Lose all power and car will buck back and forth. Also does it when transmission down shifts and then tries to upshift when accelerating and engine warm.

The contact owns a 2005 Ford Five hundred. The contact stated that while driving 60 mph, the fail safe mode activated, causing the vehicle to stall. The vehicle was merged to the shoulder, turned off and then restarted after several minutes, as it resumed normal operation.

The manufacturer was notified who advised that there were no recalls for the vehicle and offered no other assistance. The failure mileage was 126,000.

When you are driving the vehicle will stop accelerating and a fail safety mode light comes on, if you pull over and restart it, it will restart and happens a few minutes later.

Five Hundred 6-cyl

  • 75,000 miles
Engine randomly accelerates during hot weather and cold starts. Took to Ford garage who reported defective spark plug wire. Did not fix problem which has recurred. GT error code from parts store. Ford dealer declined existence of such code. Online search revealed reports of throttle body malfunction which can be treated with fuel additive. Seemed to stop it for a while but has recurred on several occasions. Another non dealer repair shop could not find defect. Problem has again recurred with first hot(over 90) weather.

My wife, son and I were driving. The vehicle had random acceleration while at full stopped. About 10 minutes later after a full stop the vehicle had another acceleration while foot on brake and the vehicle stalled out. Once stalled out the computer displayed the following error "fail safe engine". after doing an online review I noticed that many other Ford Five hundred owners having the same issue and seems to be caused by "throttle body". please note that whenever the vehicle is on park and put into reverse, the higher acceleration takes place. I always have to be extra careful. I have to be extra careful while driving as I am afraid for acceleration and stalling out in the middle of the road.
