ESP inoperative, tire pressure sensor inactive. All fus on steering wheel not working

Hi everyone
I started my car this morning and got the ESP signal, the tire pressure sensor inactive and in addition to this i noticed all the functions on the steering wheel aren't responsive too. I always leave these on automatic but i switched to manual and they still didnt work. The car drives but i can't get lights on, no wipers working, all the functions for call and media arent responsive too. Can anyone help me with this problem.

I also noticed water under the drivers seat and the floor behind the drivers seat is also wet. I'm still wondering how this water got in and wonder if its the cause of these problems I'm facing

Pull out the inner door jam threshold- and peel back the carpet.

CAN issue might be found with corrosion in there if you have water.

Then get to cowl and find why water is getting in/into from SAM.

Here is a picture of SAM out and the innards of said driver’s threshold...
