The only thing I can think of is that when you re-enter the car the phone is not automatically recognized. Have you tried turning your iPhone all the way off and then back on to see if the Pacifica then detects and connects? The actual "Paired" phone should still be listed within your vehicle even if the iPhone isn't detected.I have a new 2018 Hybrid and a IPhone 7S. I have no trouble pairing the phone but, when I get back in the car the next day, it's no longer paired. Anyone else having this issue? Not sure if it's a Uconnect issue or Apple.
