Is a Flood-Damaged Car Worth Keeping After Replacing the Entire Wiring System?
2 Answers
It is still not advisable to keep a flood-damaged car even after replacing the entire wiring system. Generally, after replacing electrical components, the car can function normally. However, due to the extensive wiring and numerous connectors in a vehicle, prolonged exposure to water can lead to moisture seeping into the wiring, especially in areas like the dashboard and under the cabin. These areas are difficult to dry thoroughly, leading to oxidation at connection points. Below are additional tips for maintaining a car's electrical system: 1. Check the battery before and after trips: A malfunctioning battery can cause power loss or unstable current, leading to issues like electronic device failures and difficulty starting the car. Always inspect the battery before and after trips and repair any faults immediately. 2. Protect against moisture and humidity: High humidity can cause the electrical system to dampen, while prolonged exposure to sunlight can degrade it. Park in well-ventilated and rain-protected areas. If you frequently drive in rainy conditions, take extra precautions to waterproof and moisture-proof your car's electrical system. 3. Choose electronic devices wisely: Many drivers install devices like dashcams, radar detectors, and GPS systems for convenience. When selecting these devices, ensure they are compatible with your car's specifications and avoid overloading the system.
After replacing the entire wiring system of a flood-damaged car, I think we can discuss it from a safety perspective. Although the electrical system has been replaced, components that weren't submerged may still have issues, such as rusted chassis or water residue in sensors, which can easily cause malfunctions while driving and affect braking or steering. Replacing the wiring is a major project, but it's essential to ensure all electronic control units have been updated; otherwise, sudden failures on the road can be extremely dangerous. I've seen similar cases before—where owners saved money by buying repaired flood-damaged cars, only to experience erratic headlight flashing on the highway, which was terrifying. Personally, I believe unless the engine, suspension, and water-related systems have been thoroughly diagnosed, it's better not to rush into buying one. Safety comes first. Replacing the wiring is just the beginning, not the end—always have a professional technician test it before making a decision.
