On october 18, 2018 I received the power steering assist failure error on my instrument panel when turning on my vehicle. I had driven it earlier in the day without issue. Previously I had the occasional warning noise and quick flash of an error (too quick for me to read all the way) and would have momentary difficulty turning. This issue makes it almost impossible to steer the vehicle. Research indicates that it is most likely a malfunctioning torque sensor. I reached out to ford after learning of recalls for the 2009 model year. I was informed that my VIN was not included in the recall. Ford was unwilling to assist with the cost of repairs in any way. Their suggestion was to keep the receipt on the slim chance that the recall would be expanded. This is unacceptable. Had I been on a highway when this occurred it could have been fatal to myself or others. This repair will cost in the neighborhood of $1000 or more. I will need to have the work done at a dealership to ensure the repair is done correctly and that ford won't give me reimbursement issues should the recall be expanded. This occurred less than a year after the fuel inlet valve failed on the vehicle, causing it to shut down while driving and rendering it unable to be started. The rear hatch has not been able to be opened for over three years because of an issue with the latch. I have had issues with the climate control system and well. There were issues with air conditioning when I purchased the vehicle (april 2015). The issues were not apparent previous to purchase because of the weather at the time. Within a month the weather warmed up. When I attempted to use the A/C it was only blowing hot air. The dealership was willing to fix the issue free of charge because of the circumstances. However, the issue is occurring again even after having an A/C recharge performed.

The vehicle randomly shuts down while operating on the highway between 65-75 MPH. There is no warning and it becomes very difficult to steer the car. After waiting for 10 to 15 minutes the engine can be restarted and all seems to operate, until it happens again.

While in motion the car will stall causing me to pull off to the side of the road, turn the car off, then back on in order for it to work again. This happens every 10-15 miles and its really unsafe! I believe it is a defective throttle body and needs to be fixed asap before I can continue driving it.

On 1/1/2016 I was driving on 495 w in queens, ny heading back to manhattan where I live. Out of nowhere the car began jerking, a wrench light on the dash panel came on (which I never saw before) and I could tell the car was decelerating. I tried hitting the accelerator again, the car would jerk, the engine was revving but was barely moving. I knew I had to pull over and luckily I was able to navigate to the shoulder of the road. This was an extremely dangerous situation. I am a confident driver, however, a less confident or timid driver most likely would have panicked and gotten into a potentially serious collision.

Driving home from work the car went into "limp mode", pulled over to side of road, called for tow and had car taken to shop for diagnostics and repair. Shop determined it was faulty throttle body ( there were over 700,000 orders for replacements on website at this time)part was on backorder---came in, was replaced and I paid the bill of $720.60 for parts, labor, towing and taxes. I got letter from ford that part is now a recall item so I take the bill to kerry ford in cincinnati, oh and they take all of my info and send me a check for $167.85 and tell me too bad for not having work done at ford store, that's all I am going to get. This does not even cover the cost of the part alone. So as a stranded motorist, I was supposed to think of a ford dealership first instead of safety first and getting my car repaired.
