HV Battery P1A101C

They probably didn’t want to open a can of worms, it’s impossible to know how much damage there is and you can only repair one thing at a time.
Idk if it can be cleaned in place, but there are plenty of threads and videos on cleaning up the inside of the battery.
That’s an interesting code, I can’t find anything on google

 

That should be covered by your Comprehensive (damage other than collision) Car Insurance. I don't know the value of your car but I'd call my insurance agent and see what he/she says.

 

Maybe someone knows what it means, I can’t find it.
Do I see corrosion?

 

A salvage title means accident and repair?

 

If you want I can stop by and show you the docs and give a few hints on how to pull bank 5 and repair or replace. I'm at turning point

 

If you repair be sure to mesh the rodent entry points, to avoid a repeat. Assuming similar to Gen 3, the cabin air intake’s on the firewall, just below wipers/cowl, and there’s air exit ports at the rear corners in hatch, below floor.
