Can an Electric Car Still Be Driven After Being Flooded?

Sometimes a vehicle can still be driven after being submerged in water, while other times it cannot. This depends on a thorough inspection of the vehicle's systems to determine whether it is safe to continue using it. Below are the key steps for inspecting a flooded vehicle: Engine Inspection: Check whether water has entered the engine cylinders, as this can cause the connecting rods to bend and damage the engine. Fluid System Check: Inspect the condition of all fluid systems in the vehicle to ensure no water has mixed in, which could lead to foaming, cloudiness, or degradation of the oil, reducing its lubrication effectiveness. Additionally, water may carry sand particles, causing excessive wear on the engine. In such cases, the affected components should be cleaned promptly, and the relevant fluids should be replaced.
I've been driving for decades and have seen quite a few cases of electric vehicles getting flooded. Once, my neighbor's car was submerged in water, and they stubbornly tried to start it, resulting in a battery short circuit that nearly caused a disaster. Unlike conventional cars, the high-voltage battery in an EV can be instantly damaged if water gets in, with repair costs running into tens of thousands. Never take shortcuts—if your car gets flooded, cut the power immediately and let professional tow trucks handle it. After the water recedes, a thorough inspection of the seals is essential; otherwise, problems could arise anytime you drive later. Safety first—this is a lesson learned the hard way. Small puddles might be manageable, but always avoid deep water, and park on higher ground to prevent flood damage.
I've seen quite a few cases of electric vehicles being flooded. Technically speaking, electric systems are most vulnerable to water immersion. The battery pack is located under the chassis, and water ingress can corrode circuits, leading to short circuits or even explosions. Motors and control units are also prone to damage, with costly repairs. My advice is not to start the vehicle after flooding and directly contact a tow truck to take it to a 4S shop for inspection. I've personally encountered such situations during repairs, where many accidents occurred because owners mishandled the situation. Prevention is key—always check road conditions while driving, and avoid forcing through flooded areas during heavy rain. Regular maintenance to inspect sealing strips can prevent problems before they occur.
