2018 Kia Optima — driver seat clicks during left-right transitions

CityMilesCommunity StarterJul 15, 20262018 Kia Optima EXWashington DC
2018 Kia Optima EX, about 49,500 miles. I can feel a small click through the seat base in corners. Mounting bolts appear tight and power functions work. How do you isolate rail play versus the frame or motor mechanism? I am in Washington DC. I would rather test this logically than replace parts.

If it were in my driveway, swap the cheap/easy piece first on the 2018 Kia Optima and see if the fault moves. That's the branch I'd chase this week. If you share a photo of the worksheet, easier to sanity-check. This is me being the wet blanket on purpose.
