So I had received the MDPS related letter from KIA about 2 years ago. I noticed the steering had a bit foul play and will not be straight and also when moving left or right slightly will give a very low knocking noise. Took it to KIA right when I got the letter but they said it was something else not anything with MDPS and that I would have to pay $175 for diagnostic fees to get it checked out further.

Now just after new years started to notice the steering vibrates on highway, foul play, knocking noise when car engine in running and moving steering right and left. Just to be sure got tires balanced also but still issue is there.

Anyone knows that symptoms should I look for to convince the kia service folks that it is the MDPS?

What do you mean by "foul play?" I've never heard of that term used with car steering before. I heard of it to describe bad game play or criminal activity, but never as a car term.

A clicking/ticking sound would be caused by the coupler failing, as would difficulty with power assist on the steering. The coupler would not be related to the car not tracking correctly, vibrating, or having excessive free play (is that what you mean, the steering being really loose?). It sounds like they are right, and your problem needs to be diagnosed.

My bad I didn't mean foul play. I meant free play. It just has a little loose steering when steering is straight. When driving too its not loose in turning but as soon as the steering wheel is straight then it will vibrate. While its straight, I try to move steering right or left and I hear a clunking noise.

Yeah it's loose play when steering is straight and when moving slightly left or right. And yes exactly same thing when car is stopped its making the noise when moving it left or right. Hopefully kia service is able to diagnose it under the extended warranty. When your problem happened was it under general warranty of 36K or you had to pay out of pocket?

Yeah it turned out to be the mdps and they replaced it free of cost later.
You should call kia customer service , tell them you were charged $160 diagnostic fee and it didn't fix the problem, they may issue a refund to you...How long did it take for the dealer to replace the coupling, i have the same problem on my 2014 and will have to take it in soon

I did not pay the diagnostic fee. They waived it. It took 2 to 3 hours if I recall.
