Have a brand new 2018 Fusion SE with Sync 3.
Everything had been working fine with the exception of the system locking up on occasion. Turn it off and let it sit for about 5 minutes and was back in business.
Having an issue now where my ac will work fine, until I plug my phone in the USB port. Then it just blows hot air! It does this every time!
I’m currently at the dealership having it looked at, but wondering if anyone else has had this issue and what was the cause/solution?
Going to post this in the Sync thread as well in case it belongs there...
