Car Throttle Stuck Problems of Mercury Mariner

Turned the vehicle on, drove to end of street wrench aka check engine light appeared just at the same time I came to a stop vehicle started to shack and idle rough and then rpms stared going out of normal range with out a stable position. And then vehicle died twice while making it back to house where I hooked up my obd2 code reader and stated the it was a p2111 code and stated:"throttle actuator control system stuck open" .

I was driving approx. 55mph on the parkway when my vehicle gave me a kick back (shook a little) and began to decelerate until it completely stopped. I could not get the vehicle to accelerate and had to pull over to the side of the road where I turned the vehicle off, turned it back on, and was able to drive again. I drove approx. 3 miles before the problem occurred a second time, this time I was unable to make it all the way to the shoulder before the vehicle completely stopped so I ended up at a dead stop in a turn lane. I was able to get the car to the shop without any issues occurring again and was told the issue was reading as "p2112 throttle actuator control stuck closed" - the entire part needs to be replaced and will cost me $400 as it is not covered under warranty. I called fomoco and was told that they were not aware of this issue despite many complaints I have seen online through the NHTSA. I am hopeful that Ford will come through and pay for a portion (if not all) of this repair as this was an extremely dangerous incident and one that is clearly occurring with many of their vehicles with the drive-by-wire throttle. If Ford does not recall this, it is only a matter of time before someone is seriously or fatally injured. I can only imagine if I would have been driving down I-95 at the time my throttle failed.
