Hello I'm new here to the forums. I just purchased a brand new 2017 Mustang GT Manual. Everything is great I've had a 2010 GT before I purchased this one. However, when I get to speeds of 75 and higher I'm starting to hear a knocking noise coming from the passenger side. I've checked to see if there is anything loose or hanging to cause that noise but I didnt see anything. I currently have an appointment with the dealership but I was wondering if anyone else has experienced something like this. I was hoping I could maybe solve before going to the dealership. The car is currently under 1000 miles, and I'm not sure if there is any settling in new cars. This is my first new car purchase.
Thanks for your help in the future.

This would drive me crazy. Perhaps its a piece of aero trim that pops at those higher speeds.

You were right. I wanted to look over the car one more time before visiting the dealer. I was doing some research on the side skirts and I came across a video about the highway rattling. Its was actually two plastic pins under the side skirt that came loose, and when I was getting on the highway it allowed the side skirt to move and make a ton of noise. Pushed those pins in and I dont have that problem any more. I hope if anyone has this problem in the future they read this and its a quick fix.
