Wife and I are experiencing what sounds like this exact phone caller echo issue in her 2021 Explorer. We have observed it only occurs when the caller is also on a cell phone, land lines don't have any echo. Occurs after 5-10 minutes after call has started. Only the other person gets the echo (one not in the Explorer). Occurs with her Droid and my iphone 12 but only when connected via bluetooth. If my iphone 12 is connected to AppleCar play then echo never occurs. Also have confirmed multiple times sync is updated to latest version. Left battery unhooked for couple hours, but made no difference once reconnected. Disconnected and reconnected phone from bluetooth but echo still prevails. Contacted Ford selling dealer and local Ford dealer and they claim they have never heard of this problem.
What solutions if any have any of you found?
Thank you
