I had the same issue coming from a Honda. Seems like the plastic lumbar support just hits me in the wrong spot. I have a long torso. Adjusting the seat is important, but I ended up getting some foam from an upholstery shop. The seat covers zip off. Takes some effort to squeeze the foam in there. That allowed me to put some support up slightly higher and now things are good. That is until someone drives my car and changes the adjustment. Seems like a tiny tweak is the difference between not noticing the seats at all and being miserable.
Good luck!
Thank you, I might have to give that a try. I appreciate the info.
