Hi guys, Over the last week or so, I've noticed a strange "lumpy" feeling in my driver's seat back. It's very hard to describe exactly what it is, but it is most noticeable when pulling away in traffic, for example - i.e. when my weight is pushed back into it. The seat back feels like there is something loose inside it, like maybe a spring or something. I tried adjusting the headrest, but that made no difference - I don't think it has anything to do with that anyway. Anyone else ever have this strange one? Hate the idea of bringing it to the dealers already! cheers, Joe.
