Seat lumbar inflates on it's own?

[CaptLiteBeerd]

I've noticed randomly ill get in my truck after letting it sit all night and the seat lumbar will be fully inflated. If i deflated it 1/2 of the way, sometimes it feels as if it's inflating and deflating the whole drive? I know i'm not crazy... its been like this for a few days now but it's not consistent? You can't visually see any difference in the seat either... just curious if anyone else has experienced this?

I thought I was having an issue exactly like you are saying, then one day I got out my truck and left something in the center console and just reached in to grab it and felt the lumber inflating and noticed my thigh was up against the button and didn't realize. I have not had the issue since.
Your's may a real issue, while mine was user error or the ID10T error.

I thought that was a metal bar that moves in and out, up or down
