NHTSA Complaint #11542183 — 2016 FORD FUSION

This incident has happened to me more than once in the past few months. I am driving along the highway and all of a sudden I lose my power steering. The dashboard reads STEERING ASSIST FAULT. Service required. As well as Service Advance Trac. Safety issue because going at moderate speed to get onto highway and losing all power steering could cause me to go off road if in bad weather like rain or snow. In each situation all it took was me pulling off road and resetting the car by turning engine off and then turning it back on. I have take it to a Ford dealership near me and they ran a full diagnostics but couldnt find anything really wrong with it but it continues to happen at least once a month. Ive read similar incidents with Ford Fusion owners on Google and they werent sure as I that if it was the brake sensor or ABS Module that needs to be replaced. Any assistance or advice you could give me would be appreciated.
