Will a Tesla Short Circuit if It Gets Water Inside?

Tesla's powertrain has an IP68 waterproof rating, but this doesn't mean the entire vehicle is IP68. Therefore, short-term exposure to water is generally fine, but prolonged exposure could likely cause a short circuit. Compared to gasoline-powered vehicles, electric vehicles incorporate significantly more electronic components. Once these components are submerged, they can lead to system failure. Manufacturers implement sealing measures for these electrical components, but there's no guarantee of how long they can endure underwater exposure. If these electronic parts get soaked, they may fail immediately, potentially causing severe hazards like electric leakage, endangering lives. Police announcements indicate that pure electric vehicles should not drive too fast in rainy conditions. When driving through water, the depth of accumulated water on the road should not exceed 30 centimeters, with speed controlled under 10 km/h, while paying attention to dashboard warnings. Currently, electric vehicles have relatively low water wading depths; even buses can only handle 20 to 30 centimeters, and sedans are even lower.

Tesla vehicles may short circuit if water gets in, depending on the extent. I've researched electric vehicle design myself. Tesla's battery packs typically have an IP67 waterproof rating, which protects against short-term immersion and dust, meaning a brief dip in still water is generally fine. However, if you drive through deep water, such as when the water level exceeds the height of the wheel hubs, water pressure can compromise the seals, allowing water to seep into the high-voltage circuit system and cause a short circuit. A short circuit is an abnormal flow of current, which can blow fuses, burn out electronic control units, or even lead to thermal runaway in the battery, potentially causing a fire. Although Teslas are well-sealed, their protection is insufficient in cases of deep water ingress, especially after heavy rain or floods. I recommend following the manual, avoiding water deeper than the chassis, and stopping immediately to inspect the vehicle if you encounter water. In short, electric vehicles require extra caution when driving through water—safety first.

As a Tesla owner, I must say that water ingress can indeed cause short circuits. My friend's car wouldn't start after a flood, and it turned out to be an electrical short. Water conducts electricity, and if large amounts enter the battery compartment or controller, internal wiring can short out, damaging components. Tesla designs include waterproofing, like underbody protection, but it's not foolproof; shallow water is usually fine, but deep water is risky. If water gets in, don't start the car—tow it to a service center immediately. Always be mindful of water depth when driving and avoid low-lying roads during heavy rain. Protection is good, but don't take risks—a short circuit could damage expensive systems.

Tesla vehicles can short circuit when flooded, that's correct. Water contacting electrical circuits may cause short circuits and damage components. Teslas are designed with waterproofing, meeting IP67 standards, which is effective under normal conditions; however, seals may fail under deep water pressure, allowing water to intrude into the high-voltage system and create a risk of short circuits and fires. If flooding occurs, immediately power off and seek assistance. Don't underestimate this issue—short circuits pose significant hazards.
