Strange Car Noises? Here’s What’s Causing It
Have you noticed your vehicle making an unusual or funny noise? Check it before you wreck it! The area where the sound is coming from might not be where the issue is located – that said, the noise alone is enough of a warning that your vehicle needs to be looked at. Browse through our library of sounds below to make yourself familiar with the most common noises you should never ignore and what they might mean…
1. Sound: Grinding from the gearbox
Cause: The clutch is either worn or needs adjusting. This can also indicate a more serious problem with the transmission, such as the shafts and gears inside.
2. Sound: Scraping when brakes are used
Cause: This can be due to the metal backing of the pads grinding against the brake disc rotors causing them to become worn. If this is the case, the brake pads must be replaced immediately.
3. Sound: Clunking
Cause: If a clunking sound occurs when the brakes are being used, this usually indicates wear and damage to the brake discs/pads.
If you hear this sound when you drive over bumps or potholes, this might highlight a problem with your car’s suspension or the exhaust system might be loose.
If a clunking sound occurs when turning corners, there could be a problem with the steering, wheels or tyres.
4. Sound: Groaning when steering wheel is turned
Cause: A component in your power steering system might be causing friction – this can lead to you losing control over the car’s steering.
5. Sound: Knocking or pinging noise from engine
Cause: This can indicate that your engine is not properly tuned or is running on the wrong fuel.
6. Sound: Screeching when accelerating
Cause: A high pitched screech can be due to a loose or worn fan belt which needs tightening or replacing.
7. Sound: Hissing from the bonnet
Cause: If the bonnet emits a hissing sound, it could mean that there is a fluid leak. It may be that the oil or coolant is leaking onto a heated part of the engine, or that the engine is overheating.
8. Sound: A loud bang
Cause: A loud bang from the exhaust pipe is the sound of car backfiring; this happens when unburned fuel leaks from the engine and ignites in the tailpipe.
If this sound is coming from the front of the car, it could indicate a problem with the engine’s fuel, ignition or exhaust system (this can be caused by a blockage in the fuel filter, old spark plugs or a malfunctioning catalytic converter).
9. Sound: Rattling beneath the car
Cause: This sound is typically caused by a loose exhaust system, suspension or brakes. It may also indicate that something has become lodged in the system.
10. Sound: Roaring during acceleration
Cause: This sound can occur because the silencer is no longer working properly, meaning that your exhaust system may be rusted or damaged. In turn, this could be letting exhaust emissions filter into the cabin.
11. Sound: Tapping from under the bonnet
Cause: This might mean the engine is low on oil and needs topping up.
12. Sound: High-pitched squealing
Cause: A high pitched squeal can sound because your fan belts have become loose or worn.
13. Sound: Squeaking from wheels
Cause: This could mean that your brake pads are worn or there is a problem with your brake system.
