Steering column making rubbing noise when turning. It felt like a notch was rubbing against something. The car was no reason for this part to deteriorate the way it did. It just all of a sudden started this notch rubbing feeling in steering. I took car to Calavan KIA in Lithia Springs, GA to have it examined. They said the MDPS flexible coupling needed to be replaced. There are other KIA's that had this same issue, but repair was covered in recall.

At any speed above 30 MPH, the steering system has a delayed response. As you torque the steering to hold a position on a crowned road surface, the steering finally recognizes a steering input command and immediately jumps to the new position.

I have four cars, this is the only "fly by wire" car of the lot. All others have "analog" steering which enables continuous pressure to be applied to the steering system to maintain position on the road. This is an extremely unsafe situation. I have the turbo optima. The dealer "solution" was to "take the steering off sport mode" an
