Will the car get water inside on rainy days?

[DiDelaney]

Heavy rain will not cause water ingress in vehicles. During heavy rainstorms, cars parked in underground garages or passing through deeply flooded road sections, or with improperly closed windows, may experience water ingress. Here are specific instructions regarding vehicle wading: Do not restart the engine: If the engine stalls during vehicle wading, immediately turn on the hazard lights, shut off the engine, and turn off the ignition. Do not attempt to restart the engine, as doing so can cause fatal damage to the engine and will not be covered by insurance. Ensure vehicle sealing: If the vehicle is stationary in a basement or parking lot and becomes submerged, lock the vehicle, do not attempt to start the engine, and maximize the vehicle's sealing as much as possible.

As someone who frequently commutes by car, I've personally experienced several instances of water leakage in the car during rainy days, especially with older models. The main issue is the aging of door and window sealing strips, which harden and deform over time, allowing water to seep in during heavy rain and wetting the carpets and interior. Sunroofs are also a potential hazard, as drainage holes can easily get clogged with leaves or dust, causing water to backflow into the headliner and lead to corrosion. Additionally, when washing the car or parking in flooded areas, water can enter through door gaps. My car once had completely soaked carpets after being parked in a low-lying area overnight during heavy rain. It's best to check the sealing strips and sunroof drainage system before the rainy season and replace the strips regularly to avoid leakage issues. If water does get in, dry the interior promptly to prevent mold and health issues. By the way, modern new cars have better sealing, but maintenance is still essential.

As a car enthusiast who enjoys tinkering with my beloved vehicle, I know that water ingress during rainy days is common but preventable. The key lies in the sealing strips—replace them if the rubber shows signs of aging or cracking, as even light rain can seep through otherwise. Keep the sunroof drainage holes clear by using a soft tube to blow out any blockages. During the rainy season, avoid driving fast through puddles, as the splashing waves can flood the chassis joints and cause electrical shorts. If water does get in, don’t take it lightly—wipe it dry with a cloth and use a dehumidifier to eliminate odors. Additionally, park on higher ground and avoid spots under trees where fallen leaves accumulate, as these areas pose a higher flooding risk. Make it a habit to check the seals monthly to extend your car’s lifespan—safety always comes first.

Having driven for decades, I've witnessed various instances of water entering cars during rain. The main culprit is failed sealing strips—rubber hardens over time, allowing rainwater to seep inside; clogged sunroofs can also cause backflow. Driving through water or parking in flooded areas can lead to water ingress, especially in older models with larger gaps. Timely repairs can save you from major headaches.
