Driver side Lumbar

Hello all, I have a 2020 Challenger Hellcat and the lumbar on the driver side all of a sudden won’t deflate all the way. I can inflate and it works fine, goes up and down without issues. I deflate and it deflates to a point but still it complete deflation. Went to the dealer and they had a Hellcat with the same seats on the lot and I sat in just to make sure it wasn’t me and it isn’t me. The one I sat in you can feel it fully deflate the service dept said they don’t feel a difference. I even made the new Hellcat feel like mine, they sat in both and said they are the same. Then I had them sit in the new car and deflate it the rear of the way which it did and they still said nothing is wrong. So pissed with a $70,000 car and driving it is painful to my back. Anyone hear of this or any suggestions, Going to call dodge about and file a complaint. They said they can’t just replace the seat, but I can’t believe the seat can’t be fixed. Thanks.
