My 2019 Bolt Premier's backup cameras will occasionally get 'stuck in reverse' for a while, seemingly when I go into reverse before the infotainment system has had a chance to finish booting up. Does Chevy have anything to say about fixing this bug?
Ummm...wait until the car finishes booting up? All kidding aside, I adjusted my "car-starting procedure" in 1997 to allow our EV-1 to completely boot up before doing anything. Now, I start the car first, then close the door, adjust the seat, put on my belt, adjust the mirror, etc. By then, the car's finished doing its thing.
It's like waiting for you PC to boot, except the car has something like a dozen processors that need to agree that they're good to go. Give it time...
