2017 bolt wont go into drive, random error codes.

Right now my 2017 bolt will turn on, but wont go into gear. For context, last week it pulled up a check engine code, p2516, discussions here seemed to indicate it was minor.

Then today it got a lot worse, when i turn the car on i get a lot of random warnings on the dash, stabilitrack, pedestrian friendly alert system, transmission, and an ice possible drive with care warning. The last one is particularly baffling because its 90 degrees out.

When i try putting it in gear, it doesnt respond at all, it does not give me any more errors or notifications, it just doesn't respond at all when i try and put it in gear. Neutral does still work for what it's worth.

I plugged in my obd reader and it gave me tons of error codes, like a dozen, all seemingly random stuff again, and clearing them didnt fix anything.

I am surprised that many things could have gone wrong all at once when its been driving great until now. Before i have it towed to a service center, does anyone have any advice as to what the issue could be?
