If you haven't heard of or experienced this problem, essentially there's a $3 plastic coupler inside of our steering column assembly that will completely disintegrate over time. It is not a recall on the Cadenza, but on Both the Optima and the Hyundai Sonata for specific years they have actually extended the warranty on the repair for this part to 10 year unlimited miles.
Great dialog here, and even a picture of someone's Manufacturer letter from Kia.
It happened on my car, just had it repaired for free. I have the extended warranty with deductible. But after calling the Kia Preferred line and setting up a case based on the Optima model extension, they waived the $50 deductible. If you are out of warranted, it's likely a 1-2 hour job, not sure how they would bill it as my invoice says 0 in the prices, but probably about $120-200 best guess.
The easiest way to test for this, at least it was very apparent in my car, with the car running (running because of the relationship with this coupler and power steering seemed to make the issue more apparent then with the car off) just rock your wheel side to side an inch or 2 in each direction. if you feel loose, clunky or some noise developed, your coupler is already falling apart.
It's funny because I'm a spirited driver, but because I routinely never turn the wheel while the car sits still to eliminate any excessive tire-wear from those still rotations, I never actually noticed the symptom. Been teaching my son to drive, so it was through that process of a different driver behind the wheel that we discovered the problem. A little research and I saved $50. Steering wheel feedback and function feels amazing again, like brand new. I thought she was just showing a little age..
