Never drive through standing water of an unknown depth. Here's why:
Transmission. Water makes the gears slip.
Brakes. If the rotors are extremely hot, exposure to water can warp them. The result is your car will vibrate when you try to brake. Water may get into the brake lines and cause brake failure immediately or later.
•If your car is flooded, check with your insurance agent to verify extent of coverage before repairs begin.
•If your car stalled because of flooding, have a mechanic look at it before you restart it.
