Is it serious if the car is flooded up to the seats?

It is very serious if water enters below the seats. When a vehicle is flooded, it is highly likely to damage the engine and electrical systems. Generally, it is safer if the water level is below the air intake. Methods to deal with a flooded car: In most cases, a water level slightly above the cabin floor is not critical. First, pull out the vehicle's dipstick to check if water has entered the engine. If there is water in the dipstick, replace the engine oil and oil filter first, then inspect the air filter. If the air filter is dry, you can attempt to start the vehicle. If the air filter is soaked in water, it means water has flowed into the cylinders through the throttle. If the car is forced to start, it can also damage the engine. It is necessary to remove all the spark plugs from the engine, then turn the key to move the pistons up and down, spraying out the water that entered the cylinders. After repeating this several times, clean the water from the spark plugs, replace them, and install a new air filter. Then, you can try to start the vehicle. It is essential to check the condition of all the vehicle's system fluids to avoid foaming and contamination caused by water ingress, which can lead to fluid deterioration. Brake fluid and the four-wheel brakes are also items that must be inspected.
A car being submerged to the height of the seats is indeed a serious issue, as it involves both vehicle safety and daily usability. Once water rises above the seat level, it can seep beneath the seats and into various electrical systems, potentially causing short circuits or corrosion. For example, the area under the seats contains air conditioning ducts and electronic modules, which can fail after being soaked, making repairs time-consuming and costly. In the long term, interior components like carpets and seat foam are prone to mold growth, leading to unpleasant odors and health concerns. I recommend not driving the car immediately if this happens and seeking professional inspection and repair to avoid minor issues escalating into major expenses. Additionally, during the rainy season, park in elevated areas to prevent such incidents, and regular maintenance can help reduce risks—keeping the interior dry is crucial.
