Spent some time at my dealership today about this. They have multiple vehicles like this some worse than others. They spent 2 hours on all the connectors and plugs and they have assured me that it is software related. According to them the sound cut out, CarPlay drop is in the software.
My CarPlay still drops, Bluetooth audio is choppy from time to time and the entire unit becomes unresponsive to touch periodically.
Please update the uconnect jeep!
