It's a 2023 Bolt EUV, I bought it new at the end of 2022. My issues with it only started last year; it was a great car up until then, easily my favorite vehicle out of all the ones I've owned. The issues with my car are the rear cameras, which have stopped working, and the touch screen, which no longer responds to touch.

The repair techs couldn't find anything wrong with the cameras, and their diagnostic tool reported that they were apparently functioning. They ended up replacing the cameras and the cabling, but it didn't help at all; the new cameras just stopped working again within a couple of weeks. When I took it back in, they told me straight up that they didn't know what to do about it if replacing the cameras and cables didn't work, so there was nothing left to do.

The touch screen broke around the same time[†] as the cameras, and this is worse than not having cameras IMO. The Bolt is nice because it has a good amount of physical buttons to control things, but there are still some critical functions tied to the touch screen that you just can't do if it's not responding to touch. Examples: I can't look at the front or side cameras; I can't adjust the defrost at all in the winter (it's tied to the touchscreen unlike the rest of the climate controls); I can't select a destination or add stops in Maps without opening my phone; and I can't install or decline software updates for the vehicle, which nag with a very loud chime every time the car is parked.

The dealership offered to replace the touch screen, but only as a replacement for the entire head unit which was going to be $2500 or more. I couldn't justify the cost on a car that's only worth $15k now, especially after they couldn't fix the cameras.

[†] Makes me think the two things are related, but there's no practical way to debug it on my own.

I answered in more detail here (https://news.ycombinator.com/item?id=48051714), but mine has two major issues: the rear cameras stopped working even after a full replacement, and the touch screen stopped responding to touch. The Bolt is nice because it has a bunch of physical controls for climate, music, etc., but there's still some critical stuff tied to the touchscreen that has made using it without touch really difficult.
