You should have the codes scanned to see what codes are stored. You may just have a bad sensor like a speed sensor. When a vehicle is flooded, they may not have a problem after being dried out, but problems after time can start due to corrosion on all the connections that may have gotten soaked. The electrical connections on a car are designed to repel water and not be water proof. I recommend having an expert inspect your car to diagnose your warning lights and make the correct repair.
