I just bought a '14 wrx hatchback and I ****ing love my car. I've wanted a wrx since they came out when I was 16 and I finally got one. My problem is I'm getting rattling noises from the internals of my doors when I play music. I haven't really cranked the volume too much, but with the lower bass kicking in with some songs I can hear parts vibrating in there. It's driving me crazy. Is this a common and/ or simple fix or is my car vexed?
