What is your question?
We purchased a Toyota Pruise c (2015, basic model) a from the dealership in 2015 and everything has been great so far.
But, we recently noticed a feeling like something is pushing on our lower to middle of our back when we are sitting in the drivers seat (it happens occasionally, maybe every 4 months). It will push and then stop. I can replicate the feeling by having my kid sit in the back seat and push their foot slowly into the middle of the back of the drivers seat (while I'm sitting in it). Feels almost exactly the same.
I'm wondering if this is some kind of automatic lumbar support, like an air bladder or mechanical actuator in the back? The car doesn't seem to have any buttons to control any lumbar support and manual says nothing about this model having lumbar support.
I noticed a bunch of plugs and cables / tubes under the drivers seat with some of the tubes going into the back of the seat. Is this related?
What makes this problem better or worse?
nothing, it's random
How long has your 2015 Toyota Prius C had this problem?
just in the past couples years, maybe 3 - 4 years after purchasing the car (brand new)
