Carmine has a Chevy Bolt with Apple CarPlay and every time he hits a bump, Carplay disconnects. What gives? Leo says that the only logical conclusion is a loose connection. But he can also check to see if there's lint in the lightning port. A little dust will cause a looser connection of the lightning connector. A little canned air should solve it. Also, try a different cable. Lightning cables can get damaged easily. The other side may be loose as well. Past that, it's a visit to the service department at Chevy.
