What is a Flood-Damaged Car?
2 Answers
Flood-damaged cars refer to vehicles that have been submerged in water and then sold through certain channels to used car markets across China. Below are the potential hazards associated with flood-damaged cars: 1. Damage to Electronic Control Units (ECUs): These ECUs can become oxidized due to immersion, often requiring inspection and replacement; otherwise, the vehicle may not operate properly. Since many electronic components cannot be accessed all at once, they may appear fine during repairs but could develop faults later during use. These issues mean that some flood-damaged cars may experience malfunctions even after being repaired. 2. Engine Damage: The water can harm the vehicle's internal electronic control systems. The engine is particularly vulnerable—never attempt to start or turn over a flooded engine, as this can cause severe deformation of the connecting rods. Additionally, prolonged immersion can lead to deformation, roughness, and unpleasant odors in materials like carpets and seats, as well as bacterial growth.
I've driven for over a decade and seen quite a few waterlogged cars. Simply put, it's when a car gets submerged in water, like during heavy rain, floods, or accidental sinking. Once it happens, water can seep into the engine, electronic systems, and interior seats, causing various damages. If water enters the engine, it might be totaled immediately because water can't be compressed, which can damage the pistons. Electrical components short-circuiting can cause lights and air conditioning to fail. Even worse, mold can grow inside, creating weird smells when you turn on the AC, affecting health. I've seen a friend spend tens of thousands on repairs after a flood, with insurance only covering part of it. So, always try to park on higher ground, drive slowly in low gear through water without stalling, and if it happens, cut the power and call a tow truck ASAP. Prevention is key—don't underestimate the destructive power of natural disasters.
