What problems are likely to occur after a car wades through water?

[TylerLynn]

After wading through water, cars are prone to the following problems: 1. Chassis rust: When a vehicle wades through water, dirt and debris can adhere to gaps in the chassis and other areas. Over time, this can lead to chassis rust and even component failure. 2. Headlight water accumulation: In older vehicles, the headlight covers may not be tightly sealed, allowing water to easily enter the headlights during wading. This can create condensation on the inner surface of the headlight covers, affecting light transmission. 3. Engine compartment wiring harness damage: The engine compartment contains numerous wiring harnesses and circuits. After driving through water, the connectors of these wiring harnesses may become wet, leading to short circuits and potential damage to the ECU.
