I drove through a puddle of water on a rainy day. Literally probably 30 minutes later after driving all these lights in cold start popping up but my check engine light hasn’t came on yet, but I was getting all types of warning lights like EDC unit low energy charge batteryfog, lights, damp lights what else drivetrain malfunction but before that the car was riding real good no problems so I don’t know is it is it is it something electrical? I don’t know I’m trying to figure it out.?????

Hopefully the water wasn't as deep as seen on the YouTube Channel, Rufford Ford, Vehicles vs Deep Water.

Honestly, any car older than 8 or so years, that has seen it's share of proper Winters and Summers, should NOT assume the electrical connector seals are still water-proof.

As you have found out, driving your car in the rain (even heavy rain) is NOT the same a water immersion.

Your best bet is to allow your vehicle to drain/dry (in a garage?), then run ISTA, clear the codes, then start working each "hard" fault one-at-a-time.

Let us know how you fair....
