Steering Is Tight problems of the 2014 Toyota Highlander

My Toyota Highlander 2014 has a huge security and safety issue. Its steering wheel jammed and it become completely disabled while I was driving and the engine wont start again. It has the following messages in the dashboard. 1- �eps failure. Steering wheel is harder to turn�. 2- �the engine has stopped. Please put the shift lever to p�. 3- �trac off� 4- �brake override system failure�. My car had same issue back Aug 2017 but the Toyota dealership claimed that they didn't see such issue and the car started normal. I don't know what kind of diagnostics they performed because I am having the same issue which has similar symptom as the recall issue (NHTSA campaign # 15v14000) for Toyota Highlander 2015 models. It is a very dangerous security fault because my car was idol while I was driving and the steering wheel jammed. On both occasion the vehicle was stationary.

I was backing out of my parking space and the vehicle jerk. Then a warning sign appear on the dash that said eps failure. The steering wheel was hard to turn. I began to struggle with the steering wheel at that point it was lock. After several attempts; I was able to pull into an empty parking space, parked the vehicle and had it towed to dick dyer in columbia SC. The dealership was not able to confirm what was actually wrong with the vehicle. At this time, they think they found the problem. The technician stated he has never seen such a problem before and was not sure how to fix it. I did not purchased the vehicle from dick dyer instead I purchased it from sparks Toyota in myrtle beach SC. They are aware of the problem and I was told to call the central office. I was told by the central office to complete the arbitration process. I am in process of doing this now. At this time, I do not feel comfortable driving this vehicle and instead would like a different vehicle. At dick dyer no one wanted to sign off on the service invoice stating the car is fix. I feel no one wants to be liable for any future issue with the vehicle if this does not fix the problem.
