My 2021 Bolt touchscreen had many problems early on, and the dealer replaced the radio unit after diagnosing it as the cause. (the problems had nothing to do with the radio functioning). Then things were better, though sometimes the display would just switch to a black background on its own, without being touched. As the weather got colder and i started using the A/C, the radio would come on every time I either turn the A/C on or change any setting. I took it to the dealer. The very nice tech person who said he has all the EV training offered by Chevy, looked into it. 30 minutes later he came and told me that apparently that's the way the touch screen is wired, and there was nothing to fix! What a pain. The radio also comes back on after I shut the car off, and doesn't turn off again until I exit the car and close the door. Who planned that? The radio settings require one to take one's eyes off the road to make any changes. Why does the radio have to be controlled by a touch screen? It is not safer. AND, that big message that comes on to tell you to be careful about taking your eyes off the road to manage the touchscreen, that you have to look at the touchscreen to touch in the right place to make it disappear - has anyone figured out how to turn that message off? I don't need to be told every time I drive my car. Once, when I started driving the car, was enough.
I do love my Bolt, but have grown to hate the way the touchscreen is configured. I've read of problems the rest of you have had with your touchscreens - Chevy, please listen! Stop trying to make the touchscreen do everything! I would love to have regular, old knobs and buttons to manage the radio with. My previous cars had them, and still managed the blue tooth pairing to interact with my phone/ipod.
