Tesla Model 3's chassis has a certain waterproof effect, but it is not recommended for the car to wade through water. The risk coefficient of wading vehicles is very high, and the circuit is prone to short circuits, fires, etc. Composition of the car chassis: The car chassis consists of four parts: the transmission system, the running system, the steering system, and the braking system. The function of the chassis is to support and install the car engine and its various components and assemblies, forming the overall shape of the car, receiving the power of the engine, enabling the car to move, and ensuring normal driving. Composition of the transmission system: The transmission system generally consists of the clutch, transmission, universal transmission device, main reducer, car chassis, differential, and half shaft.

As an enthusiast particularly interested in the technical details of electric vehicles, I must say the Tesla Model 3's chassis design boasts impressive waterproofing capabilities, especially its battery pack which achieves an IP67 protection rating. This means it can withstand immersion in 1 meter of water for 30 minutes, making it resistant to daily rain or small puddles. However, this doesn't mean the entire chassis is completely waterproof – components like suspension or parts around the tires may still get damp. In case of major flooding, issues could still arise. When driving my EV, I always remind others to regularly inspect the chassis sealing strips and avoid prolonged parking in waterlogged areas. If you must traverse deep water, maintain a speed below 10 km/h to prevent potential short circuits in electronic components. While EV battery waterproofing prioritizes safety, improper water exposure can damage the vehicle and shorten its lifespan. It's advisable to check for water stains below the tires after every rainfall as a preventive measure. Overall, it's sufficiently waterproof under normal conditions, but recklessness should be avoided – safety comes first.

With over 20 years of driving experience covering both electric and gasoline vehicles, I'd say the Model 3's chassis performs quite well in terms of water resistance. Its battery system has solid dustproof and waterproof capabilities, meeting IP67 standards which means driving in rain or minor urban road puddles poses no major issues. However, don't mistake it for a submarine that can plow through deep water—other chassis components like motor controllers or wiring junctions might risk leakage, especially in older vehicles where sealing rings tend to degrade. My advice to owners is to maintain caution: avoid large puddles during daily driving and have technicians inspect the chassis' anti-corrosion coating during regular maintenance. After driving through heavy rain a few times, I checked the undercarriage and found no issues, but high-speed water wading increases the chances of hydroplaning or water ingress, potentially affecting braking. Responsible driving extends vehicle lifespan—this is crucial. Never assume the car is completely waterproof.

As a daily user with children at home, I prioritize vehicle safety. The Model 3 does have waterproof capabilities for its chassis, with an IP67 rating protecting the core battery to prevent short circuits and fires. However, it's not completely waterproof—if driven into deep puddles, water may enter at chassis connection points or wheel bearings, causing abnormal noises or malfunctions. I once experienced a taillight failure after driving in the rain, which required towing; the diagnosis revealed water had seeped into small circuit components. My advice is to slow down in waterlogged areas and avoid driving through water deeper than 15 cm, as it affects both the vehicle's lifespan and pedestrian safety. Regular car washes and inspections can help detect water stains early.

I've owned my Model 3 for just six months as a new owner, and I feel its underbody waterproofing is quite good—no issues during rainy commutes, with IP certification ensuring battery safety. But don't mistake it for amphibious: exposed areas like drain connectors may get damp, and splashed mud can accelerate circuit wear. I once drove through a small puddle without problems, but deep water could corrode metal parts. Simple maintenance like timely car washes to remove mud helps with waterproofing; avoid reckless mods when modifying, keeping the factory design optimal.
