Hi everyone! I bought a new 2016 V6 new last month. After about 400 miles I started to notice this clunking/knocking sound coming from the front whenever I go over small bumps or uneven road. It's hard to describe it so I'll link a video of it but it sounds like a hallow knock coming from under the car. First time I heard it I thought I had a flat tire. The weird thing is that it ONLY does it after a cold start and will go away after a few minutes of driving. I'm worried it will get worse once he weather starts to get cooler. I took it to Ford (showed them this video) and they kept it overnight but said they couldn't hear anything and that everything underneath looked good. Any ideas?
