What Causes the Abnormal Noise After a Car Drives Through Water?

[Jane]

Reasons for abnormal noise after a car drives through water: 1. Brake pads getting wet: If the water is not too deep and splashes onto the brake pads, it is normal to hear abnormal noise when braking. In this case, just drive normally until the water on the brake pads dries up. 2. Foreign objects stuck between the brake pads and calipers: If the water is not too deep, foreign objects like plastic bags or mud in the water can get stuck between the brake pads and calipers, causing abnormal noise when braking. This can be resolved by cleaning the brake pads. 3. Water entering the exhaust pipe: If the water is deep enough to enter the engine through the exhaust pipe, it can prevent the fuel and air mixture in the engine from burning properly, leading to abnormal noise. In this situation, the car should be moved out of the water immediately, and the engine should be cleaned. Otherwise, it may cause engine failure or even total engine damage.
