"Faintly"--you are probably trying to hear things. IF your Rap was built 12/11, the serious sound issue is not in play with new parts installed according to others after late Nov. Also, don't drive with windows down If there is a 'serious' issue Ford might do something about it...but then again maybe not LOL. Hey I have a 12/9 with no issues--sounds exactly like my two 2019's and 2018. I think you are probably trying to hear something that is not there if built 12/11. Enjoy it.
