Common Noises Your Car Can Make And What They Mean

Common Car Noises

One of the most common questions our expert team of in-house mechanics receives on a regular basis is:

“My car makes a strange noise, what does this mean?”

Here are some pointers as to the different sounds that could be coming from your car, and what they could mean.

Squealing from the engine while driving

High pitched squealing noises usually point to an issue with a belt or pulley, indicating a required replacement or re-adjust.

Hissing from the engine

A signal that the engine could be overheating, which can cause serious trouble further down the line. It also could point to a fluid leak under the bonnet, a leaking turbocharger pipe or a damaged intercooler.

Squealing sound while braking

This is a tell-tale sign of worn brake pads. If the noise becomes the sound of grinding metal, you’re seriously damaging your brakes. Have it checked as soon as you can.

Grinding sound from your gearbox

This noise is indicative of a potential problem with the clutch or transmission.

Rattling sound from the engine

This is a very confusing noise as it could be a number of different problems – including issues with the oil, a faulty clutch fan or a stretched timing chain. Nevertheless, these all require urgent inspection.

Rattling noise from underneath your car

This noise could, amongst others, be a sign of a loose part of your exhaust system.

Clicking while turning

Faulty CV joints are usually the reason for this noise and should be checked by a mechanic right away.

Clicking sound from the engine

Usually, a sign that your engine is running low on oil. If it persists after an oil top-up, have your engine checked thoroughly by a professional.

A loud knocking from the engine

This could be indicative of a lack of lubrication, or something has broken within the engine set-up – or is about to break. Either way, seek the services of a professional mechanic to get the issue seen to.

Humming or growling noise from your tyres

The first thing to do when you hear a noise from your tyres is to check the pressure. If the pressure is correct, have your wheel alignment and balance checked and possibly adjusted.

If any of these noises are coming from your car, the next mechanic is only a click away.
