I’m starting to have similar issues more frequently now after more than a year of it being pretty stable. Has Ford done anything to help you resolve the issue?
Brand new IAG grille for $425. Never been installed. Local pickup only. I’m in Orange County area.

My other car is a Lexus and my wife has a Hyundai. Both of those cars’ turn signals are much quieter so that is my baseline. This is my first Ford so that’s probably why I’m noticing it.
The turn signal is so loud that I don't even use it half the time. But there's a way in Forscan to reduce the volume to something more tolerable. I didn't see this posted anywhere else so I wanted to share it here.
Run the IPC module configuration.
Then set the Turn Signal Speed Sensitive...
