My daughters car has a dashboard that is lighting up like a Christmas Tree. Dealer doesn't know the problem wants to put on new wiring harness do something with transmission for 4k. I'm diagnosing from 1000 miles away.

Codes are p0700, c0057, c0045 and p2765.

I'm going to post everywhere to see if anybody has a clue.

Calling Cash Davidson.

P2765 Input/Turbine Speed SensorB Circ
P0700 is transmission control module malfunction
C0045 - Left Rear Wheel Speed Circuit Malfunction
C0057 is either a wheel sensor or other ABS issue

I would start by cleaning/ and tightening all the battery connections, then check the condition of the battery and alternator.

What year is it?

Exactly what I have told my daughter and son in law. Sounds like there is not enough current going to the system. They want to go to the dealer and argue with them. Wisconsin is the worst place in the world to get anything done, I don't know what the deal is. I told them to go to advance and have the alternator checked.

Yeah, alternator and probably battery too. I've heard of weak batteries causing some funky stuff. Either that or maybe a bad ground somewhere, just replacing the harness certainly sounds like something a dealer would do. Dealers don't ever seem to be able to troubleshoot electrical gremlins, they just know how to replace parts.

Maybe try and check out a local shop that specializes in Subarus?
