I own a 2015 Ford f150 and while going through the mcdonalds drive through, at approx 5 mph I lost power steering unable to turn left or right. Errors displayed on dash for electronic power assist fault, advance trac fault, hill start assist fault. Also no cruise control. Pulled over in an empty parking spot, shut down the truck and restarted the truck, but there was no change to the string. Unable to drive further, I had to have the truck towed to nearby dealership greenway Ford in orlando. Per the service department, the steering control module is bad and will require replacement of the steering rack. Cost to me $1700. I purchased certified pre-owned extended warranty, but unfortunately the warranty doesn't cover steering rack. I am grateful we were not driving on the highway, as this could have turned out horribly.
Pulling out in motion on to a busy street I lost all power steering almost getting into a major vehicle accident. Once losing powers steering cause me to go in other lanes of traffic.
Driving on interrstate 70 at 65 mph, I had several alerts begin flashing ranging from check 4x4, hill assist failure, 2h, parking brake and many more. In addition I lost power steering, brake lights and turn signals. I was able to drive truck home. This happened 4 more times. I called dealer and they suggested I drive it to their establishment some 20 miles away. I did not feel safe and contacted roadside assistance to tow the truck. I had to beg for a loaner one week later I received a call stating the technician needed to drive the truck to see if the same alerts happened even though they found 12 plus alerts when they analyzed the truck in their shop. I allowed this to occur as I wanted answers. I received a call today stating they had found the problem, a wire had became corroded in the steering column causing all the alerts to malfunction. They are replacing the entire column and my truck will be completed by Tuesday. I had purchased this truck just 4 months prior and have been a loyal Ford customer for 30+ years.
