Will the car be damaged if the wheels are submerged in water?

There are three scenarios when a car is submerged in water: First, the water level covers the exhaust pipe but does not reach half the height of the wheels; Second, the water level just reaches half the height of the wheels; Third, the water level exceeds half the height of the wheels. Generally, if the water level just reaches half the height of the wheels, it can affect the car. How to handle a submerged car: 1. Water covering the exhaust pipe: When the water covers the exhaust pipe but does not reach half the height of the wheels, move the car away promptly. Starting the car at this point will not cause water to be sucked back into the engine. While driving, slow down to prevent water from entering the engine's intake system. 2. Water just reaching half the height of the wheels: If the car's sealing is good, it generally won't let water in. However, if submerged for a long time with poor sealing, the car may leak. Ensure the engine's intake system is not flooded, then drive the car to a 4S shop to remove and dry the soaked interior. 3. Water exceeding half the height of the wheels: If the water exceeds half the wheel height, both the engine and cabin may be flooded. Do not start the car in this situation, as it could damage electronic devices and components.
Last time it rained, my car got flooded up to the wheels, and my heart nearly jumped out. If the water level reaches halfway up the wheel hubs, it's already very dangerous—the engine might suck in water and seize up, leading to complete failure. Repairs could cost thousands or even tens of thousands. Wet battery wiring can also easily short-circuit, and issues like malfunctioning AC or stereo are minor in comparison. Especially for modified cars with lower chassis, the risk of damage is higher. My advice is to avoid flooded areas if possible. If you must drive through, go slowly and never accelerate, ensuring water doesn’t splash into the air intake. After driving through water, immediately check if the air filter is dry—otherwise, you’ll regret it.
