NHTSA Complaint #11588118 — 2023 CHEVROLET BOLT EUV

Dashboard went blank for a second and reset itself twice while driving at 65 mph in the mountains of AZ, near sunset. This happened once in 18k of driving, right after infotainment system partially failed: audio failed and parts of touch screen failed to respond. Danger is in the unsuspecting driver's reaction in poor driving conditions. Call to On Star was initiated but it uses the same audio system the infotainment system uses. So On Star failed. Pulled over; restarted car several times, infotainment system was silent. 2 hours of driving in silence; parked for 2 hours; restarted car and everything was back to normal. Took it to dealer. Unable to recreate this problem. Updated software downloaded to infotainment system. No information if this fixes problems. Until we understand why infotainment problems may cause dashboard to go dark, this car is unsafe for unsuspecting drivers. My wife was driving; I in passenger seat, she won't be driving this car again until this is understood better and fixed. Thank you for your help
