2021 Westminster. Drivers seat just stopped providing the massage function and it seems like the upper drivers side (left) bladder is still inflated. Popped the rear cover off and was greeted with an octopus of tubing (see below). Looks to be like a two distribution points for the air system. Connected to a motor? Some people have had issues with the PRV (pressure release valve) but unsure where that is.

Here is a seat for sale disassembled.

Now the button for massage on the center screen is acting temperamental. Won’t light up for both sides randomly.

I ended up just shutting off the auto start for the massage function. Lo and behold after 3 days of no use it started working as it should.

I’m glad its working but pessimistic about how long it will last. Oh well. Love this car.
