2003 Hyundai Elantra

Car went into a puddle there was a sudden pouf of smoke and car was smoking when parked no obvious sign of damage was seen but it was recommended that I check the?Wiring? Drove the car 10 miles and car
broke down plastic surrounding radiator was cracked
and engine smoking a friend replaced the radiator and refilled coolant started for work next day car broke down coolant leaking and enging smoking towed to
Hyundai dealer diagnostic check was told water pump
radiator hoses bypass hose thermostat total 6.5
hours labor parts 200.00 bill 937.00 drove car to work next day 15 miles and returned home later same day car would not start gas would not feed towed to another garage said that car started but engine running too rough conversation about tune-up cylinders missing etc. Could I have shorted something that first day when I went into the puddle that would set all of this in motion what is going on with this car?
