I, uh, accidentally took a Subaru for a swim years ago. Made a U turn in the 9th day of constant rain in an unfamiliar area. The “U” involved a dropout I couldn’t see through the flooded water. It was a Christmas dinner with a first date in a black dress in the passenger seat. I somehow had the presence of mind to kill the ignition as the entire passenger side of the car went under. I looked at the sky through my window, saw the water under hers, and said, “I think you’re getting out on my side.”
the entire engine was submerged. More than half the dash, including my new Sony cassette player.
3 hours later we had it pulled out. Car started and ran no problem. Drove it 300 miles the next day in the snow. I pulled up all the carpet after that trip and did what I could to dry it out. Never had any issues with the car except it would smell funny on rainy days. BUT, I was indeed an early bitoger and changed fluids regularly.
