Loud Bang Under Car When Driving

March 10, 2024

Whether it’s a clunking sound while driving over a pothole or a loud bang when turning the steering wheel, unexplained sounds coming from your car are never good. Oftentimes they signal that something has broken or has gone loose. Some, like a rattle or squeak, are easy to fix while others might require more attention and money. If the sound is accompanied by your check engine light, it’s important to address it right away.

Rattling noises from under your car may mean that your serpentine belt is worn out and needs to be replaced. This belt helps your car’s various systems run smoothly. If you don’t get it fixed, your vehicle could start to overheat or stall while driving.

If you hear a hissing sound when you accelerate, this could be an indication that your radiator coolant is leaking into the engine. This causes your car to lose power and often comes with a burning smell.

A whirring noise when you turn the wheels or corner can indicate that your front-wheel-drive or four-wheel drive CV joint is wearing out. These joints are used to transfer power from the gearbox to your wheels when you turn or steer, and they should be replaced as soon as possible to prevent further damage to your steering system.
