Apparently, a stiff suspension and no resonator make these cars go nuts. I just found the buzzing noise from my center console. The shifter bezel goes nuts!! I think there is another buzz coming from the passenger door (TSB?). The driver seat is driving me crazy. Getting in and out it sounds like an old Ford Maverick!! I've even repositioned the seat up and down. This stuff drives me crazy and I don't know how to deal with it. I've traded cars in the past because the dealer either couldn't find the source or said they all do it. Granted, I get to tell people that as well, it sucks when you get told that. Sometimes I like to just ride in peace and quiet after listening to customers, techs, and managers gripe and moan all day........ SOS!
