What to Do When Your Car Is Submerged in Water?

During heavy rain, if your car is submerged, the first priority is to quickly exit the vehicle and move to higher, safer ground. After the heavy rain and floodwaters recede, do not attempt to power on or start the vehicle, especially for high-end brands and models. Tow the vehicle to a 4S shop or repair shop for a comprehensive inspection to assess the extent and scope of the water damage, including checking whether water has entered the engine's air intake. Clean the affected systems and components, ensuring that absorbent parts are deodorized and dried to prevent mold growth later on. Once the vehicle is thoroughly cleaned and free of residual moisture and dampness, proceed with power-on testing. If necessary, replace any damaged electrical components.
If the car gets flooded, based on my experience with several similar situations, the first step is not to touch the engine—just turn it off and exit the vehicle immediately. Once water enters the engine, attempting to start it may cause piston seizure, resulting in thousands of dollars in repair costs going down the drain. Safety comes first—quickly move to higher ground or a safe location, and avoid lingering in the car to prevent risks from rising water or electric shock. Afterward, contact road assistance or your insurance company to arrange for towing, as professionals will handle the next steps. During repairs, thoroughly inspect the electrical system and fluid conditions, as waterlogged cars are prone to rust and short circuits—comprehensive cleaning and replacement of damaged parts are necessary. When driving, always pay attention to weather warnings; if water exceeds tire depth, don’t force your way through—taking a detour is wiser. Experience has taught me that prevention is better than repair, and life is far more important than the car.
