What to Do When Your Car Is Flooded?

[VanEmmanuel]

Seek maintenance and repairs immediately as rainwater and sewage have strong corrosive effects on the vehicle body. Flooded vehicles should be towed to a repair shop for treatment. Contact your insurance company to arrange for damage assessment. Request repairs, disassembly, and cleaning, along with rustproofing treatment for the vehicle chassis. Inspect the brakes, brake fluid, and electrical circuits, and ensure proper ventilation and dehumidification inside the car.

I remember last time my friend's car got flooded, the water had already reached the door when he got out. The most critical thing in this situation is not to force-start the engine, as a second ignition can cause severe damage to the engine. You need to first assess the water level—if it's only up to half the wheel height, quickly push the car to higher ground, turn off the engine, and remove the key. If water has already entered the car, immediately unbuckle the seatbelt and open the door to escape. If the door won't open, use an escape hammer to break the corner of the window. After that, contact the insurance company to file a claim right away and arrange for a tow truck to take the car to a professional repair shop. During repairs, a thorough inspection of the electrical system, engine, and transmission is necessary, and all water-contaminated fluids should be replaced. The towing fee can actually be claimed from the insurance company, so remember to keep photos of the scene and repair receipts.

As a technician who has repaired over a hundred flood-damaged vehicles, I recommend first turning off all power in such situations. If the water level exceeds the exhaust pipe, do not attempt to move the vehicle, as water backflow can immediately destroy the engine. Evacuate to a safe location promptly and call for rescue, while also notifying the insurance company. Once towed to the repair shop, we typically perform a full vehicle disassembly inspection: removing and airing out all carpets and seats, using professional equipment to dry wiring harness connectors, and checking if the engine block and transmission have been flooded. Electronic modules are prone to oxidation and corrosion, and some main computer boards that have been submerged for too long can only be replaced. The most troublesome part is dealing with the subsequent musty odor, which requires repeated disinfection and ventilation. Not only are the repair costs high, but the resale value of flood-damaged vehicles also drops significantly.

Seeing news reports of vehicles in distress due to water submersion, I think it's crucial to remind everyone about the most important escape techniques. The moment the vehicle stalls, you must make a decision: if the water level is below the windows, open the door and escape; if it's above the windows, immediately unlock the doors and power windows. If the power windows fail due to water ingress, use the metal rod from the headrest to pry the corner of the window, and there's also an emergency release handle in the trunk. After escaping, call the police immediately and place a warning sign on the roof of the car. Once the water recedes, use your phone to take photos of the vehicle's location and damage—these photos are critical for later claims. Remember, don't cling to belongings inside the car, and before heading out in heavy rain, it's best to check weather warnings.

Dealing with a flooded vehicle requires immediate action. In many cases I've handled, drivers made fatal mistakes. When the engine stalled, water was only up to the wheel hubs, but forcibly restarting the engine resulted in a major repair costing 30,000-40,000 yuan. After safely evacuating, immediately contact your insurance company to arrange a tow truck. Remember not to disassemble or repair any components yourself before professional servicing. The repair shop needs to inspect the waterproofing of all vehicle wiring harnesses, especially the engine control unit connectors. Brake fluid that has become cloudy due to water contamination must be replaced, and the fuel tank should be checked for water ingress. The seatbelt pretensioners may fail when exposed to water and should be tested. When selling a used car, flood damage history must be disclosed to buyers - concealment may constitute fraud.

Last year during the heavy rainstorm, my car was submerged up to the dashboard in the underground garage. The painful lesson learned is that post-disaster handling must follow proper procedures. After filing the claim, I followed the insurance company's guidance to conduct a damage assessment, which resulted in the replacement of the entire electronic steering column and airbag sensors. The repairs took one and a half months, costing over 70,000 yuan in total. It's advisable to keep an emergency hammer and a life whistle in the car at all times. Footage from the dashcam showing water submersion can serve as evidence for insurance claims. During repairs, make sure to oversee the replacement of all vehicle wiring harness connectors and the ECU. When evaluating a used car, a flood-damaged vehicle typically depreciates by over 40% compared to a normal one. In case of severe weather, remember to move your car to higher ground, and purchasing additional water submersion insurance can provide extra peace of mind.
