I have several annoying noise sources that I'd like to get rid of. Other than those, the car is perfect. The steering wheel: in the last week or so, the steering wheel developed a kind of a scratchy sound when being turned to the left, like plastic being rubbed against plastic or rubber. It appears the noise is coming from behind the steering wheel. Rear shelf: something rattles in the rear shelf that houses the rear speakers, the noise is something like metal against plastic, the noise appears on every surface, but predominately on bad roads. Front seat: creaking sound coming from the lumbar area of the driver's seat when pressure (my back) is applied, it's very irritating. Seat belt: Looks like the area where the seat belt height is adjusted produces an irritating rattle when driving on bad roads. Any known TSB's or ways to fix these?
