Will There Be Problems If the Car Doesn't Stall After Driving Through Water?

[StAxel]

No. Driving through deep water is very dangerous for a car. Remember, if you encounter deep water, it's better not to take the risk and avoid driving through it. Once the car is submerged, the damage can be significant. As long as no water enters the interior, it should be fine, but even if water does get inside, it's not a major issue. However, it can easily cause water to enter the engine, leading to the need for a major engine overhaul. Even if the engine doesn't take in water, it may still cause water to seep into the floor or damage the brake transmission control unit. Precautions for driving through water are as follows: 1. Check the garage drainage system: If your car is parked in a high-risk area for flooding, you should regularly check the garage's drainage situation. During the rainy season, park the car in a safe location. 2. If the car stalls in water, it means the engine has already been affected by water. Attempting to restart the car at this point may cause severe damage, such as piston scuffing or cylinder breakage, which can be fatal to the engine. Therefore, if the car stalls in water, seek help immediately to push the car to a dry area. Do not stay in the car waiting for rescue.

I drove through a stretch of waterlogged road earlier, and the engine didn't stall, which immediately put me at ease because it meant the air intake wasn't flooded and the engine was unharmed. However, I always have some lingering concerns afterward—what if the chassis got submerged, and the braking system or exhaust pipe got clogged? That could make the brakes feel spongy, making driving in the rain dangerous. I remember last time after crossing a waterlogged area, I noticed a sloshing sound under the car—it turned out to be water trapped in the exhaust pipe causing the noise. I took it to the repair shop, and luckily, they cleared it out in time. My advice is to check the exhaust outlet and electronic components after driving through water. If the water depth exceeds the wheel hubs, it's best to rinse the chassis to prevent rust. After all, waterlogged areas are often muddy, and prolonged exposure can corrode the frame and affect suspension performance. Regular maintenance is the real key.

I've driven through quite a few flooded roads. When the engine doesn't stall, it's generally fine, but don't celebrate too soon. Water entering the exhaust system can easily cause blockages, and sudden stalling while driving is actually worse; wet electrical circuits may short-circuit, and failures like ABS sensor malfunctions can be dangerous. Once, after going through a puddle, my brake discs were soaked, increasing the braking distance, and I almost rear-ended someone. I recommend quickly drying the brake components afterward and checking the filter for mud and sand. Floodwater often contains corrosive substances that accelerate chassis aging, especially for older models, so extra caution is needed. Installing waterproof guards can prevent this issue, and developing a habit of regularly inspecting the chassis ensures safe and stable driving.

The engine not stalling indicates no water intake, which is generally safe, but other hazards remain. For example, water accumulation in the exhaust pipe can obstruct exhaust flow, reducing engine efficiency; damp electrical components may short-circuit, causing headlight failure or starting difficulties. Water can also seep into bearings or suspension components, accelerating wear and rust. It's recommended to check tire drainage holes after each water crossing to ensure they're unblocked and run diagnostics to confirm the electronic control system is functioning properly. Prompt cleaning is crucial.
