My car is a 2017 Ecoboost Premium Convertible with less than 20,000 miles on it. I am having an issue where I am hearing a semi-loud rattling noise when going over small bumps. It seems to be louder at slower speeds and is loud enough for me to hear it over the radio when it is set on 8-10. It also appears to be loudest when I am using the brakes to slow down, but happens with or without the brakes being used. I have an appointment to take the car in to the Dealer on Wednesday, but was wondering if anyone else has had this issue so that I can have a few ideas about what to have the dealer check. I have read in a couple of places that there is a FSB on a couple of different bushings in the front end that could be the culprit, but wanted to possibly get a few other ideas before taking it in. The car is not modded in any way and is fully stock at the moment. Thanks in advance for any help!
