My 2017 Volt has started dropping blue tooth phone connections. After the loss of the blue tooth connection, the touch screen phone icon goes gray. Then the phone reconnects and the icon glows red. Worse is the fact that the Volt is really bad a playing music from a usb thumb drive. Sometimes the car does not recognize that the drive is plugged into the usb port. Other times it starts playing music and then stops and the touch screen goes completely black. After a minute or so the touch screen revives and a different song starts playing. Screen then goes black again, etc. Taking to dealer tomorrow. Have had car for less than two months. Shame on Chevrolet!
