Driver's seat lumbar/back support shifting/pop

[miatawnt2b]

I have a 2012 Escalade with power lumbar/back support. When I adjust my position on the back of the seat though, that lumbar unit seems to shift and make a pooping sound.
Anyone ever hear of this issue?

No Pics, but I found the issue. I took off the back of the seat and found that the pressed sheet metal piece had cracked in half horizontally about midway down. It's a dumb design that fatigues the metal every time the lumbar is adjusted. So I cut an 9.5" x 11" flat piece of plastic from a rubbermaid tote lid, placed it between the seat and the metal lumbar, and zip tied it tight to the metal fingers on the sheet metal (4 fingers on each side, so zip tied a total of 8 places along the lumbar)

Works perfectly now, and the plastic has no chance of fatigue.
