Lumbar Support
I have a 2015 Z with the performance seats.
The lumbar support will not stay where I set it. It sinks back into the seat after a few moments. I’ve tried saving it in memory too but that didn’t work.
Anyone else have this issue?
Thanks!

My 15 was doing the same. I didn't notice it for a while since I didn't spend a lot of time in the car on trips. What I had noticed was the bladders had to be pumped up each time I used the car.
The first time I took a 3 plus hour trip in the car I noticed the lumbar and the side bolsters would slowly deflate and I would have to reinflate them every 30 to 40 minutes. The dealer replaced the driver's side modules under the GMEPP extended warranty. The cost billed to GMEPP was $742. I think the module parts came to about half of that. There are several places where the unit can leak. The hoses that feed the various bladders, the bladders, or inside the pump itself. Since the parts have been replaced the bladders stay inflated unless I change them.
