It''s all related. The "LKAS has a problem" message is on as well pre-collision warning system and am sure BLIS is also off. I scanned what am Abe to communicate with ad got this. I don't even see where the side cameras for the BLIS are on the mirrors but I see on the inside of the door that it does have it.

From your screenshots, the big one is:

U3000-49 - Multipurpose Camera Unit / Millimeter Wave Radar Internal Electronic Failure

No, the BSI sensors are not in the mirrors. They are radar units behind the rear bumper corners. And based on your codes, I would start by diagnosing the front radar/camera system. I would clear the codes, then turn the car back on and without driving it run the codes again. That way we can see which comes come sus first.

I see. Where is the Ian camera behind the rear view mirror? This is a one owner vehicle with only minor accident that happened in 2016 when it was new, on back left, but I doubt it has been left like this since then. I will look under rear bumper hopefully they are visible.I also read couple of places that it could be related to a weak battery. Car starts but I feel a minor struggle so I will charge it and re run the car and see what I get. Also read somewhere that it could be transmission related

I don't think it is either the battery or the transmission, did you clear the codes and then turn the car on and rerun the codes? This will tell us which code is most prevalent.

I cleared all but I cannot communicate with all systems as they are separate, scanner says not supported, but with the main camera I have the code even after I clear all; u3000-49

Yep, so the "Multipurpose Camera Unit" is up by the rear view mirror, I would check that out and then get a used one from ebay and try that, these camara are subject to heat which makes them go out. Then clear the codes and let me know.
