I've had my 2019 Forester sport for about 7 months now. About a week after buying it I stated getting horrible upper back pain when ever I drive. I mean everytime! usually within 15 minutes or so. low back feels great. Just mid/upper back issues. And it goes away as soon as I stand up out of my car. I've never had this issue with any car before. I've tried adjusting the seat and steering wheel in every way imaginable with no relief. I've tried my own homemade pillow remedies, and had no luck. Before I start dumping money into trying expensive fancy cushions I just wanted to see if anyone else has this issue. I'm 5'4'' 150, and the seat has an inward curve right in the center of the back rest. I'm thinking maybe I'm just too short for my back to contour properly to the seat back?? I'd love some input!
