Hey all. I have been reading that plastic on plastic crackling/straining noises is "normal" for WRX models, but I've had mine for 2 weeks and for the past few days I've heard a plastic on plastic crackling noise near the rear passenger seat. It seems like it's the plastic casing around the small window on the side - where the round plastic inserts are, but I can't really tell. All I know is that it's annoying as all hell.
Any suggestions about what to look at? I checked the seatbelt to make sure that wasn't it - but it's not a metal on plastic sound.
