Can a sedan still be driven after being submerged in water?

Generally, a car can still be used after being submerged in water. Additional information is as follows: 1. Introduction: A flood-damaged car refers to a vehicle that has been soaked in water, typically meaning the engine and transmission have been submerged, with the water level exceeding the wheels and body seats, and the bottom components of the vehicle being in prolonged contact with water. Such vehicles pose significant risks, as the electrical circuits are prone to short circuits and fires. 2. Hazards: Flood-damaged cars often have sand and gravel that cannot be completely cleaned out, remaining in areas like gears or belts, which can lead to certain components being easily damaged and may produce unusual noises initially. In general, repairing a water-submerged vehicle involves removing the seats, interior trim, and panels to drain the water and clean the mud. The engine also needs to be dismantled to inspect electronic components, especially checking whether the computer motherboard is damaged.

As someone who has long dealt with vehicle failures, I understand the significant risks of waterlogged cars. If the water level is below the wheel height, the situation might be slightly better, but if it exceeds halfway up the tires, you must be vigilant. Water can enter the engine through the intake, causing hydro-lock and completely damaging the engine, with repairs often costing tens of thousands. Even worse, electrical system short circuits can occur, and submerged battery terminals or the vehicle's ECU can easily lead to fires, posing a threat to personal safety. Waterlogged interiors can also lead to mold and odors, causing long-term corrosion to the frame. My advice is to never start the engine and immediately call for a tow truck to take it to a professional repair shop for inspection. Remember, waiting a few days for it to dry is only superficial; deep-seated issues like transmission water damage and failure may still lurk. Parking in low-lying areas should be avoided to effectively prevent these troubles.

I always emphasize safety first. Driving a flooded car is absolutely a risky behavior. Once the engine ingests water, it could be instantly ruined, with repair costs running into thousands of dollars. The high risk of short circuits may lead to fires or loss of control while driving. Not to mention internal wiring corrosion, which could cause brake failure and other hazards over time. To protect yourself and others, I advocate immediately disconnecting the battery's negative terminal to prevent short circuits and calling for professional towing services. Do not attempt to start the car yourself, as insurance policies may not cover such man-made damages. Choosing safe handling methods far outweighs the consequences of regret. Every time I see the flood-damaged car yards after disasters, those rusted frames remind me that patiently waiting for professional assessment is the wiser choice.

From my personal lesson, starting a flooded car is a big no-no. Last year during heavy rain, my car got submerged. I recklessly tried to start it, causing the engine to cough and stall. In the end, I had to replace the ECU at considerable cost. When water enters mechanical systems, lubrication is compromised, and parts rust quickly; electrical circuits are prone to short circuits and malfunctions. Even drying it out for several days isn't enough, as hidden issues like blocked AC lines can cause endless trouble later. So now I'd say: leave the car as it is, find a technician to inspect it with professional tools, and only proceed when safety is confirmed. For daily parking, choose spots away from waterlogged areas—prevention is the most cost-effective and worry-free approach.
