Car keeps dropping bluetooth sync

Intermittently my Android ( V7.1.2) phone does not sync with my new 2017v-5. This only happens when I first start the car. Once sync'd it stays sync'd for the remainder of the trip. About every 4 times I turn the car off and then back on, the phone will not sync. To sync it, I have to go to my phone bluetooth settings, turn it from ON to OFF and then back ON. The car then syncs. My previous car was a 2007 Prius and I never had any problems nor do I have any problems with my wife's Ford Focus. Any ideas would be helpful.
