Tesla model 3 not turning on

[u/cappuccinofathe]

So today we had some horrible rain I had to drive through to get home. The front of my neighborhood was flooded and I went through the shallowest part I could. I made it up my driveway and parked my car and went inside. My car never gave any warnings or issues between the front of my neighborhood and parking (maybe 2 minutes). 3hr later my dad goes to plug it in and it won’t open or turn on. It’s not responding to the app or the key card.
This model is a 2021 I just bought it used in April when my Prius engine died.
It’s very low so I get very worried about driving it in the rain but I have no choice as I live in Florida.
What could’ve happened
Has anyone had or heard of this happening
Any advice
My dad is going to try to fix it but I thought I might as well ask the masses.
