Mine stopped changing stations and acting erratically. The touchscreen doesn’t respond in certain places when I touch it. I’ve been able to live with that. I’ve been planning to look into getting the screen fixed but haven’t yet

The research if been doing the digitizer in the touchscreen could be going bad or the control unit which I believe is attached to the back of the touchscreen but not for sure. Yesterday on my way home from work I didn’t touch the screen at all and kept it on the home page and only Bluetooth connected. It barely twitched for a few minutes after driving thirty minutes like it was going to change pages but it never did. I want to try and check the touchscreen connections this weekend. The one thing I don’t understand is why mine acted up a month and half ago for a week then worked perfectly fine until last week.

I’m having the same issue. I have a 2018 Silverado. About 1.5 months ago mine acted up for about a week. The radio stations would constantly change on the touchscreen. The display in the dash was changing from info to radio setting at the same time. It stopped acting up until the other day when it started again. I checked the plugs behind the glove box for the hmi module yesterday Those were good. Still acted up today. If anyone figures this out please help.
