2018 Terrain SLE
Driving along and decide to make a phone call. The Infotainment screen went black. Phone will not connect. Radio cannot be turned off even when car is turned off.
Holding on line with OnStar.

Waited about 20 minutes and went to check car. Looked like GMC Screen re-booted. Everything looks good. OnStar said that dash reboots to prevent battery being rundown. Crazy!
