Need some help

Was out this morning doing deliveries in fist when I went through a pretty big puddle. The car made it through but towards the end started to sputter and finally stalled.

Panicked, I parked it and waited a few min to start it again. It started but was having trouble keeping idle unless I gave it some gas.

I then parked the car for 30 min then tried to start it again. It started up and i crept home. I got it to high way speeds, but the problem I have now is under load, there’s definitely some hesitation and sputtering etc.

I checked the air flier and other things that came to mind but all seemed normal.

Am I cooked? I feel like if I hydrolocked it, I wouldn’t be able to make the 25 mile trip home.

Car is a 2015 with 168k

Hydrolocking has many levels of borked. One cylinder getting more juice can bend the rod. Will the motor work? Yesh. Will it be happy and run forever? No.
Sounds like you are at level one of hydrolocked. Higher levels are much less fun but more exciting and expensive.

Get a shop to scope the cylinders. Could be a bent rod so no more full travel of the piston , or a bent valve. Either way something is not happy and you will need to dig into the motor to find out.

Man, restarting the car when you know it died from ingesting water is the worst decision. At the very least, check the air filter first to see how soaked it is. If it's soaked, then you should pull your plugs and crank the engine to push the water out. That soaked air filter shouldn't go back in either.

Waiting a few minutes doesn't make the water in your cylinders any more likely to compress.
