2017, 17,000 miles: drove about 8 miles to an appointment, returned to the car an hour later, pressed the 'Go' button. The car started up as usual, driver's display working, but the infotainment screen was dead. Did the usual; shut down the car and restarted, pressed buttons aimlessly, said a few curse words, and headed for home. A couple of miles down the road, the familiar "Bolt" came up on the screen, and it proceeded to boot up as usual, radio working and all.
As far as I know, the software is current; I installed an update soon after I got the car in November of 2017, and the dealer installed another a few months later.
Anyone else have this problem?
I guess I can consider myself lucky that the driveline computer booted up OK.
