Steering Rack And Pinion problems of the 2017 Ford Explorer

At around 35,800 miles, I noticed a slight jerk of the steering wheel when going around curves. I was going 70mph on the highway for a quick afternoon trip out of town. On the way home (36,000 miles) it was doing this even when driving straight. I had my husband drive it when I got back, and that's when we decided to get it to the nearest dealership (45 miles away). The whole rack and pinion steering column was severely corroded and needed to be replaced. I was without my vehicle for over a month while Ford gave us the runaround on whether or not it would be covered since we were almost 200 miles out of warranty by the time the vehicle was at their facility. When driving it there going about 40mph on the highway, the power steering went out entirely and threw the car clear across the road. Thankfully it went to the right and into the ditch, because had it jerked to the left, we'd probably be dead. It jerked all over the road the whole way to the dealership.
