Is it problematic for water to reach the car chassis?

[Don]

If the water level just reaches the chassis, there is generally no significant impact as long as it is not submerged for an extended period. Hazards of water-damaged vehicles: The reliability of such vehicles cannot be guaranteed, and the likelihood of future malfunctions increases. Automobiles contain a large number of electronic components, and if submerged, the reliability of the vehicle in future use may be compromised. Even after replacement, reliability cannot be fully assured. Odor issues: After being submerged, water-damaged vehicles can usually only be treated through rinsing, drying, and sun exposure. As a result, some hidden areas can easily become breeding grounds for bacteria, potentially leading to unpleasant odors.
