Cruise Control Problems of 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.

This has happened several times at freeway speeds on freeways. This issue occurs when using adaptive cruise control if the vehicle encounters a panic stop situation and determines it is unable to autonomously stop in time. When the collision warning activates and the driver uses the brakes, the adaptive cruise control disengages the autonomous braking and braking is reduced until the brake pedal travels a significant amount. This increases the stopping distance and may cause an accident. The behavior of the adaptive cruise control should be changed so that a driver applying the brakes disengages adaptive cruise control acceleration (if active) but does not disengage adaptive cruise control braking (if active). I had a 2005 Jaguar with adaptive cruise control and it did not exhibit this behavior.

While driving on the highway 70 mph speed limit the car stop accelerating and slowed down to the equivalent of driving in "cruise control" at 30 mph. A yellow wrench warning light turned on. Took car to Ford dealer and they felt problem was consistent with a throttle part problem and they recommended replacing the part which I did and fixed the problem. Of note, by the time I had the car towed to Ford dealer (day after incident) the warning light was off and Ford dealer said that the car system had no record of event.

Driving on highway w/ cruise control engaged at 65 mph speed. Suddenly car loses complete acceleration & propulsion ability, resulting in car to slow down rather suddenly. I was able to pull onto off ramp in my case, but if I was in a different location, I would have definitely been in a very dangerous situation/serious accident. I turned off vehicle and restarted the vehicle a few minutes later. Proceeded to the highway again, experienced the problem again, this time I was only able to pull over to the left shoulder, which was quite narrow to begin with. "wrench symbol" appeared the second time and stayed on with check engine light on. Car was unsafe to drive further. The check engine trouble shooting codes I had were p2111 and p2112. Cause of this issue is known to Ford motor but they refuse to include hybrid cars in their "consumer satisfaction program 13n03". Throttle body control module senor, including the entire assembly is defective as Ford has agreed to replace this on millions of cars across various model years, including the fusion 2010, but not Fusion Hybrid versions. Ford states they will not repair problem that I experienced recently under this established program which NHTSA was proponent for. The defective part in question is the throttle body assembly and sensor which is no different than the part in the non-hybrid version for the same model year. Real hazard to driver and I was lucky that I was not rear ended as a result or in a serious car accident from this known defective part. Ford motor must be required to notify all affected owners who will/have experienced this problem to have it repaired at their expense, as this is a serious safety issue that must be taken seriously given number of vehicles that are involved that will experience this. I experienced this at mileage of 75k but I have read that others have had this happen at much lower mileage.
