Hi dee! I haven't found similar complaints around the web. Make sure you know all about your adjustment options on that seat including lumbar adjustments if any. You can find that in your owners manual or just start fiddling with the knobs and switches. There's also a pretty good market for seat inserts that can help ease problems particular to your back's relationship with your seat. Good luck!
I have an '06 and have had no problems at not. I've even driven it to Georgia from Texas and back.
