Hi. I have a 2017 GT350 with just over 3000km on it. It's fantastic and I love it dearly. The car has developed an annoying rattle issue a few weeks ago. The sound seems to be coming from the drivers side door panel / instrument cluster area. It doesn't start happening until you hit about 80km/h (50mph). I live out in the country and have to travel down a few uneven roads to get home, although I'm very careful with bumps, I'm thinking that something has loosened up. I used to work for a car audio shop and I'm comfortable removing car interior/trim, so I've checked inside the door panel and under the steering wheel area. Any loose cables have been tied up. BUT the rattle persists and I'm wondering if anyone else has this problem or if anyone has any ideas. Thanks!
