Hi folks, I have about 50K miles on my Model S and i'm hearing a "ticking" type noise on back/bumpy (but not too bumpy) roads or when I stop/start coming from what sounds like inside my seat or my passenger seat. Going with my standard procedure I waited for a passenger to notice, but its driving me crazy. Its obviously not something serious but it sort of sounds like a lose paperclip dangling on a string inside the seat somewhere clicking against metal. Anyone else have something like that and any ideas how to get rid of it? I've tried reaching around, having people crawl over the car to listen etc but so far its eluded me.
