The armrest on my driver's seat squeaks like crazy. Every time I put any weight on it, it makes an awful sound. I figured I'd have it checked out next time I go in for service. But I may just remove the damn thing if it drives me nuts before my next tire rotation.
When there are heavy winds, I get a louder than usual amount of wind noise that appears to be coming from the passenger side front door, along the front edge. Had that checked out, but the dealer of course found nothing. It only happens in high cross-winds at highway speeds. Of course when they took it out, there were no high cross-winds. But it has happened to me since, so I know its still there.
Some of Portland's roads are really terrible in that they have not been paved for what seems like years, and they have a sort of texture to the surface that makes the car buzz. This affects all vehicles, but I sometimes also get a vibration noise when driving over those roads that sounds like its coming from above me and to the left. I've tried tracking it down, but can't seem to pinpoint where its coming from. Hard to do when you're driving. Anyway, it could be coming from the same source as the original post from Casualsurfer. I'll push on the headliner next time I hear it and see if it doesn't go away.
I seem to be particularly sensitive to road noise and complain about stuff that other people don't seem to be bothered by. So much so that as quiet as the Spark EV is, I'm considering wrapping the whole thing in Dynamat. I actually used a sound meter app to test the decibels in the car as I was driving. I tested the Spark EV and a late model 5 Series BMW in the same area at the same speed. There was no discernible difference between the two as far as the app on my phone was concerned. So kudos to the Spark for being at least as good as the BMW, in that regard.
