My 2020 ct5 is having the same issue and the crazy thing is Cadillac dealership never heard of this fix. Would this fix my car.
My 221 Equinox screen randomly blacks out for a minute then restarts, happens cold or hot. Sometimes can drive 10 miles no blackout, other times blacks out 5 times. Reprogram by dealer had no effect. New HMI behind glove box had no effect. Car only has 17,750 miles.
My 2021 Equinox, 17,800 miles, has major infotainment blackout issue. Radio randomly shuts down for about a minute then comes back on. Dealer reprogrammed the system and it still blacks out randomly, when very cold and when very warm, not related to temp. Sometimes happens in 1/2 mile from start of drive, other times several miles. May shut down once, and other times every 2 to 5 minutes.
