On my new 2017 Signature model, when I turn the wheel sharply either right or left at speed, I often hear a slight clunking sound, almost as if unused hanging seat belt clips were knocking against the pillars or something hard might be shifting in my glove box. It's hard to localize the sound but it sounds like it might be under the dashboard. It's driving me crazy trying to figure out what it might be. Anyone have a clue?
