Does Water Submerging Half of the Wheel Have Any Impact?

[MacMatthew]

In general, water reaching half the height of the wheel can already affect the car. If water submerges beyond half the wheel, both the engine and the cabin may take in water. In such cases, do not start the car, as it could lead to the burning of electronic devices and components. 1. Water submerging the exhaust pipe: When water submerges the exhaust pipe but does not reach half the wheel height, promptly move the car away. Starting the car at this point will not cause water to be sucked back into the engine. While driving, reduce speed to prevent water from entering the engine's air intake system. 2. Water just reaching half the wheel height: If the car's sealing is good, water reaching half the wheel height usually won't cause water ingress. However, if the car is submerged for a long time and the sealing is poor, water may seep in. Ensure the engine's air intake system is not flooded, then drive the car to a 4S shop to have the soaked interior parts removed, cleaned, and dried.
