Automatic Emergency Braking problems of the 2017 Ford Explorer

On freeway, pushed brakes but vehicle did not stop or slow down resulting in multi car rear end collision. Auto braking and abs features did not engage. Vehicle was towed and our insurance agent claim adjuster recommended we reach out to you. No warning lamps, messages, etc. Went off at the time or had gone off previously.

Initially the cars check engine light came on intermittently for about 3 days, then one day while driving the wrench light came on and the car immediately started decelerating - almost as if I was breaking hard, and would not accelerate over 30. After turning it on and off multiple times the light went away for days until my appointment with the mechanic, that same day it came back on. We went to a Ford dealership and they said it was the throttle body and repaired it. Two weeks later the same issue occurred. I know this was a big issue in 2016 and earlier models, I believe the problem was never fixed in 2017 models. Our car is currently in the shop and they are "emailing Ford" about what to do. The first incident I was on the interstate when I stopped abruptly and the second was on the highway. I luckily had no one behind me both times otherwise this could've easily caused an accident.
