How Long Can a Flood-Damaged Car Last?
2 Answers
For vehicles affected by flooding, if promptly repaired and thoroughly cleaned at a professional auto repair shop, they can typically run for five to six years without major issues. However, there are still certain risks involved, and it is not recommended to continue driving a flood-damaged car. 1. Risks: Waterlogged cars are prone to electrical system short circuits, posing a risk of spontaneous combustion. Critical systems such as ABS (Anti-lock Braking System), ESP (Electronic Stability Program), and ECU (Engine Control Unit) may fail during crucial moments, leading to potentially disastrous consequences. 2. Damage: If the engine is started again after being submerged in water (secondary ignition), it can cause internal connecting rod deformation, essentially rendering the engine irreparable and requiring major overhauls. Additionally, rapid cooling of heated components like the engine and exhaust pipe due to water immersion can lead to deformation and increased unbalanced stress, significantly reducing the lifespan of these parts.
How long can a flooded car run? I've pondered this question for a long time. From a mechanical perspective, both the engine and electronic systems suffer after being submerged. Corrosion begins immediately—engine pistons and bearings will rust. It might start in the short term, but water entering the fuel tank can degrade the oil, causing acceleration jitters or stalling. Once water gets into the electronic control unit, short circuits can happen anytime, potentially failing within minutes or lasting a few weeks before breaking down. If the water level didn't exceed the tires, it might still run, but if it reached the doors, corrosion accelerates, making it extremely risky to drive. At most, you might get a few dozen kilometers before needing major repairs. Regular maintenance can extend its lifespan slightly, but don't expect it to last long—safety inspections are the best approach.
