Steering Column problems of the 2016 Ford F-150

Have had this vehicle to dealer multiple times with complaint of hearing rattling under vehicle and in steering column along with noise from right front brake area. Also with complaints of vehicles wandering left and right on highway regardless of road crown. Have asked specifically to check the electric steering to ensure not faulty. All these complaints while still under original warranty. Today, two weeks after last visit, steering locks up while driving and I cannot turn the vehicle. Fortunately, I was on my property going slow and was able to stop safely. I was driving home and drove 30 miles on the interstate doing 70mph. Glad the steering did not freeze then. Shut the vehicle off and then restarted it and got the �steering assist fault service required� on the cluster along with a bunch of other symbols. The sync screen came up and froze and could not be cleared nor was it responsive to any other selections on screen. I think this is an electrical issue with either the electric steering, a sensor or possible low or interrupted voltage. This vehicle has no voltage gauge for battery nor was there any indicator that warned of a low voltage issue when the steering wheel would not turn. Is NHTSA waiting for someone to be killed with this problem before it is investigated? I am waiting until Monday when dealer opens to have them come get this vehicle. I am afraid to even attempt to do anything to it to drive it to dealer for service. I am uploading the latest service invoice for this issue. Dealer has consistently stated there was nothing wrong.

One week ago left work and turned on truck. When starting to pull out of parking space abs light came on dash. After getting home and calling dealer to have inspection, was informed it would be 2 weeks to get in for service. As vehicle is daily driver continued to drive around town and to work, a few days after regular use steering column started getting harder to turn and developed clicking sound. Called another mechanic to get in sooner and before could make that appointment scheduled for two days later entire steering column locked up and vehicle is unusable. Being towed to repair shop today. Luckily was not driving when column locked up. Had started vehicle in driveway and was planning on going to store when unable to back up because steering columns/wheel would not move. Now awaiting work from repair shop on doagnsostics and issue to repair. Very frustrated as vehicle less than 3 years old and with only 70k miles.

My 2016 F-150 has intermittent steering and handling issues. I have had several instances of temporary loss of control on this vehicle. The most severe was when coming out of a gradual turn to the right at 65 mph. When bringing the truck back straight, I felt something slide in the front axle and it felt as if the right wheel was falling off. The steering felt as if it wasn't connected during this episode, and the truck did not respond to my steering inputs. I have had several other similar events happen at all speeds from 20 mph to 65 mph. The steering also pulls to the right after turns and intermittently loses power assist. Sometimes the steering wheel can barely be turned with enormous effort, other times it feels slack and loose. The vehicle has been in the shop for this unsafe steering as well as a grinding noise coming from the right front 4wd hub. Three unsucessful repair attempts were made for the right 4wd hub, but no mention of the steering safety check I requested several times was ever made. Furthermore, the dealer and manufacturer has been non responsive to my request to get a Ford rep involved to correctly fix my truck. I am uncertain whether the steering/ handling problem is caused by the defective 4wd hub or by the steering rack or column. Because I have experienced an increase in these steering events, and I deem the vehicle unsafe to drive, I have parked the truck since August 22nd.
