My car has had this issue since I bought it CPO in '07. It's an 06. Basically, the springs in the seat back of the driver's seat (the area above the lumbar support) creak and squeak pretty loudly as you get into the seat or out of it, or if you move your back on it at all. It's pretty annoying, and it's definitely not normal because the passenger front seat is completely silent. I know that I could probably take off the back of the seat and spray the springs to make the squeak subside for a time, but I don't think that's a permanent fix. I'm still under warranty, but I really don't want them to have to replace the entire seat. Perhaps they can just replace the springs from the back. Anyone have experience with this issue?
