The hazards of a submerged car are as follows: 1. Hidden dangers: 'Flood-damaged cars' can be repaired to a certain extent, but even after repair, serious hidden dangers remain. The longer the immersion time, the higher the probability of malfunctions. This is similar to a watch falling into water; even if it's disassembled and dried, the watch will still malfunction and cannot be completely repaired. Additionally, flood-damaged cars often have sand and gravel that cannot be completely cleaned out, remaining in areas like gears or belts, leading to easier damage of certain parts and initial abnormal noises. Generally, repairing a water-submerged vehicle involves first removing the seats, interior components, and panels, draining the accumulated water, and cleaning the mud. The engine also needs to be disassembled to check electronic components, especially whether the computer motherboard is damaged. 2. Potential problems may arise at any time: In reality, a 'flood-damaged car' after repair is like a 'time bomb,' with problems potentially arising at any moment, such as the engine suddenly stalling during high-speed driving, airbags failing to deploy in critical moments or deploying without reason. Although such cars are cheap, they pose serious safety hazards during daily driving, so consumers are advised not to purchase 'flood-damaged cars' just to save money. 3. The longer the time, the more severe the damage: The longer a vehicle is submerged in water, the more components will be severely damaged due to water immersion. This can cause corrosion of internal metal parts in some of the car's computer boards, leading to poor contact, unstable operation, and other phenomena. During driving, issues like shaking and stalling may occur, and in severe cases, the computer board may short-circuit and burn out.
