The camera rear view mirror on my 23 AT4X has an issue of showing grainy, barely able to see, night time views. During daytime it is fine, although maybe a bit grainier than my rear view mirror cam on my 2020 AT4. I have meant to take it in to the dealer to look into it, but figure they will just say they see no issues as it will be day time when they have it.
I think it has to be a camera defect of some kind. I of course cleaned the camera thourougly, but it wasn't dirty nor did it look like there was anything wrong with it from what I could tell just by looking at it. I would bet if the dealership would just swap a new camera for it, it would fix the issue, as I think there is something not quite right with this particular cam. All the rest work fine, no issues like this.
