Automobiles submerged in water are not necessarily considered totaled. Generally, water-damaged vehicles are categorized into three different levels: If the water level exceeds the car's chassis, it is referred to as a water-immersed vehicle; if the water level surpasses the oil dipstick, it can be termed a semi-submerged vehicle; and if the water level has gone beyond the engine hood or the dashboard panel, then it is called a fully submerged vehicle. Here are the recommended actions for a water-submerged car: 1. Do not attempt to start the vehicle after it has been submerged in water; 2. Call for a rescue tow truck and inform your insurance company of the repair shop location where the car will be taken, so that the claims adjuster can assess the damage; 3. While waiting for rescue, if conditions permit, disconnect the vehicle's power, shift into neutral, and push the car to a safe location.

I've been driving for over 20 years and often encounter waterlogged roads or wading situations. A flooded car doesn't necessarily mean it's totaled—it depends on how high the water level was and how long it was submerged. For example, if the water only reaches below the wheels, just clearing the drainage and checking the chassis is enough. But if the water rises above the exhaust pipe or even reaches the seat level, the problems become serious, like electrical shorts or engine flooding, requiring thorough repairs. I've seen many cars that, when promptly disconnected from the battery and towed to a repair shop, can still run for a long time, especially newer or high-end cars, which have higher repair value. However, if the car has been submerged for several hours, the electronic systems are usually beyond repair, and the cost might exceed the car's value, making it worth considering a write-off. In short, don’t rush to make a decision—first consult a professional mechanic and review the assessment report before deciding.

As a car enthusiast who treats cars like my life, I've studied many modification and waterlogging cases. While water damage is certainly alarming, it doesn't necessarily mean the car must be scrapped. The key is immediate action - turn off the engine the moment it's submerged, and don't attempt to start it to prevent secondary damage. If the water level hasn't exceeded the door seam line, the car can usually be saved by cleaning the interior and checking the motor and controller. Modern cars with numerous electronics are prone to malfunctions, but professional repair shops have equipment to assess and potentially fix electronic control units. My personal tip is to replace blown fuses and clean oxidized wiring. If the entire vehicle is completely submerged, especially hybrid models, the repair costs may be too high, making scrapping the better option. For daily parking, avoid low-lying areas to minimize risks.

Dealing with flood-damaged cars requires careful consideration, and they don’t necessarily have to be scrapped. The water level is the key factor—if the water reaches the floor liner, cleaning and drying may suffice; if it rises above the dashboard, the computer system might be damaged, requiring part replacements. First, disconnect the battery to avoid short circuits and fires, then tow the vehicle away. If water enters the engine, disassemble and inspect the cylinders; otherwise, a major engine overhaul may be needed. Electronic circuits oxidize quickly, so use a multimeter to test the intact parts. I recommend evaluating the repair costs: simple fixes under a thousand yuan may be worth it, but if costs exceed ten thousand, consider scrapping the car based on its residual value. Avoid DIY attempts—send it to a professional workshop for inspection, as safety comes first.
