2017 XC-90 water damage

[Lukesmith]

I drive through a huge puddle last night that was about 2 ft deep. Someone else was passing the opposite direction and pushed a huge wave of water over my hood and then my car just turned off and wouldn’t start again. I think it’s just a sensor or something that is limiting the car and not letting it even turn over. I don’t think any water got into the engine but I’m not positive. What would you suggest I do??

Wow, where to begin... best case, the dunking blew some of the engine, battery and/or starter fuses. Did you check that? Worst case, the engine sucked up a helping of water and hydro-locked (water is not compressible). Do any indicator lamps come on when you turn the key on or is it completely dead?

It’s certainly possible to hydro lock an engine by sucking water into the intake. Quick check would be to look at the air filter, was it all wet / air ox full of water? Any resolution to this issue?
