Question in regards to the mulltcontour seats in my 2013 MKS. I have been using my massage seats more because my back has beeb bothering me. I feel like it may have not went back into position correctly as I feel a lump in the bottom of my back. I have went though the process of putting each section all the way out and returning it back to what should be flat. I can't feel it when running my hand over the the lower portion of the seat but feel something in the lower back sitting in there. That or maybe my back is just jacked. Has anyone experienced this before?
