I have 2016 RAV4 hybrid limited and drive about an hour to work and from work every day. I have been getting upper back pain mostly from that little curve on the seat at upper back area. I feel like that little curve keeps my upper back bent all the time while I am driving. I am very happy with everything else's about the car, but my back is so important for my career. I never had back problem with my previous 2007 Camry. Anyone else with the same problem?
