Will a Car Be Damaged by Heavy Rain?

No impact, as long as it hasn't been submerged in water. Flood-damaged cars: A flood-damaged car refers to a vehicle that has been soaked in water, typically meaning the engine and transmission have been submerged, with water depth exceeding the wheels and body seats, and the vehicle's underbody components have been in prolonged contact with water. Such vehicles pose significant risks, as the electrical circuits are prone to short circuits and fires. Hazards of flood-damaged cars: The hazards of water-damaged vehicles are enormous. If a vehicle is submerged in water, it can easily lead to rusting of body components, shortening the vehicle's lifespan and reducing its safety performance. For example, water damage can cause corrosion and rusting of the vehicle's wiring, leading to sudden engine shutdowns or spontaneous combustion due to short circuits while driving, with unimaginable consequences. Additionally, the repair costs for water-damaged vehicles are very high, often exceeding 50% of the vehicle's value for severely damaged ones, and insurance claims can be very problematic.
Getting caught in a heavy rain isn't usually a big problem for cars, but it depends. New cars with good seals are generally fine, while older ones might have issues. Rainwater can seep into clogged sunroof drainage tubes, especially when parked on a slope, causing water to backflow and soak the carpets. If door seals are worn, footwells may accumulate water after heavy rain. Long-term exposure to heavy rains poses greater risks - the paint gradually loses its shine, particularly in areas with acidic rainwater where stubborn water stains form on roofs and hoods. From my experience, it's best to dry the car promptly after a storm, especially around door seams to prevent moisture buildup and mold. Taking a drive post-rain helps evaporate any dampness in the engine bay naturally.
