Hello,
I've had my 2021 ST since July 2021 and have been dealing with a click in the seat when I use the massaging seats. Its definitely happening on the lower seat cushion and you can feel it click under your butt. Feels and sounds like a broken piece of plastic. The same sensation can be felt then exiting the car occasionally and on some turns. The leather seat cover on the drivers seat is not very tight to the cushion either. You can actually grab and pinch the leather. I'm thinking I have two issues going on here. A broken massager and a loose seat cover. The day I picked it up the ST a small piece of leather way sticking out of the plastic side panel that I tucked back under. That leads me to believe that maybe it wasn't installed properly.
