Cruise Control problems of the 2016 Ford Fusion Hybrid

On July 4th 2018. I was driving down freeway at approximately 74 miles per hour, my vehicle decelerated abruptly down to about 40 miles per hour then down to 20 miles per hour. Steering wheel become tight and practically locked into place. This portion of the event occured withen two seconds at most. The check engine light came on and the console screen on. The left side of accelerometer displayed multiple messages stating my safety systems where not available, adaptive cruise control was unavailable, forward collusion warning was unavailable, rear parking cam unavailable, parking sensors, unavailable, hill assistance unavailable, these where the ones I read while trying to make avoid a collision but other messages continued to display on the screen. Altogether the event in which the deceleration and messages displayed one after the other, in rapid succession, took place inabout 5 to 10 seconds. The sudden deceleration of my vehicle, from 74mph to 20mph forced a large white SUV. To quickly adjust lanes and force two other vehicles to move as well in order to avoid an accident. One vehicle was almost forced into a concrete wall but was able to stop, the cars behind had started to manuver around as well. I the driver was able to correct themselves quickly and continue on. My vehicle was unable to accelerate past 20mph. The exit was close, my hazard lights appeared to be be working, and vehicles where paying attention to my vehicle. I took the opportunity to move the vehicle off the free way and park it at a gas station. With the holiday, I couldn't find any open repair shops. While I waited for a ride I found several forums discussing this is a common issue with the 2016 Ford fusion energi. After about 12000 miles the throttle body needs to be replaced. Sense then I took mine to get fixed, the issue and fix, was replacing the throttle body. Ford won't recall!.

While under normal operation at highway speed (65-70mph with cruise control on) the car alerted me to an error ("service advancetrac") and immediately deactivated: cruise control, traction control, emergency brake assist, and a couple other systems. The check engine light also came on. The car was unable to maintain speed and began losing power. I was able to safely pull the car over to the shoulder of the highway and turn the vehicle on and off twice, the alerts and check engine light persisted through the vehicle restarts. I was able to accelerate and merge back into traffic; however, the maximum speed I was able to maintain was exactly 50mph and I think that may have only been under battery power provided by the hybrid battery system (I. E. , electric drive), since no engine noise was apparent while trying to maintain speed. I was able to park at a gas station and call Ford road side service. I have an automatic adapter on the car and the adaptor reported the error code p2112 throttle actuator "a" control system-stuck closed. The same error code was also found by the Ford dealer, which repaired the error under warranty.
