GR Supra Lumbar Support on drivers side stopped working

[gort]

While driving now and then my lower back support pumps up to the Max without me doing anything. I can’t adjust it back. Sometimes after a couple minutes I can get it back down/back again but most of the time the buttons won’t respond!
anyone else had this problem?

Fixed under warranty by Toyota......turned out to be the switch panel
