Steering Is Tight problems of the 2015 Kia Motor Optima

My steering wheel is sticking and my husband took it to the dealership to see what the problem is and they have checked it and said it needs steering column. They gave us a printout saying followed TSB cha 090 preformed effort measurement test. Measurement 4. 6 nm supposed to be 3. 3 nm needs steering column at a cost of $1400. 00 with a 10% discount because it is not covered under warranty, which we then declined to pay that amount. When we purchased the car from perry-ellis kia we got a bumper to bumper unlimited warranty "at least that was our understanding" through fidelity warranty services, inc. So when lara who works in the warranty department for the dealership which is now premier kia gave me the warranty per my she is now telling me the steering column is not covered. I have noticed that there was some kind of recall performed stating sa188 service action sa188 '15 qf steering feel improvement dealer code tx137 repair date July 10, 2015 dealer type rd. Which raises concern to me now that I am still having steering problem and they will not honor the warranty. I believe this problem should be fixed under this service campaign since the problem already existed this is not the first time I have complained about this problem with the steering wheel. Your cooperation into this matter will be greatly appreciated.

I have noticed that as I am driving on the the interstate that my steering is sticking, this too me is very uncomfortable and this should be noted as a safety concern, this problem should be looked into before t turns deadly.

Vehicle tends to steer itself and can at time of freeway speeds be hard to keep vehicle in a staring line. Vehicle steering wheel can get stiff and with and movements the vehicle tends to over correct itself. While going down a freeway or long straight away the vehicle tends to swerve back and forth when steering wheel is being held tight on one place.
