2006 Kia Sedona steering problems

I was driving the vehicle at approximately 35 MPH. All of a sudden I heard a loud thud. The wheel jerked violently to the left and my vehicle began careening left toward the side of the road. I immediately began braking. I was able to stop the vehicle and exit safely. Upon inspection of the vehicle, I noticed that the front wheels were pointing in slightly different directions, and the front left wheel was moved significantly back in its well toward the rear of the vehicle.

My vehicle shakes badly...kia, where I purchase my 2006 told me, it is the sub frame which causes my van to shake. The salt in pennsylvania causes the frame of this van to rust away. I well not be able to drive it! There is no recall...this will cost me $2,000.00. I believe if you live... Where it snows. The vehicles should be made for states which have snow.....and use salt on the roads. Why should I have to paid for this. The sub frame needs to be recall by kia manufacturer.the mileage on my van is 63,553.
