Is your car trying to tell you something? 5 noises you shouldn't ignore

Have you ever turned down your music because your car started making a strange sound?

Whether it's a squeal, knock or rattle, unusual noises are often your car's way of telling you that something isn't quite right. While not every sound means an expensive repair, ignoring persistent noises could turn a small issue into a much bigger one.

Here are five common car noises every driver should know.

Squealing when braking

One of the most common noises drivers hear is a high-pitched squeal whenever they apply the brakes.

In many cases, this means your brake pads are wearing thin. Most brake pads are fitted with a wear indicator that produces a squealing sound when it's time for a replacement.

While the car may still stop safely, replacing the brake pads early can help prevent damage to the brake discs, which are much more expensive to replace.

Grinding when braking

If the squeal has turned into a grinding or scraping noise, don't ignore it.

This often means the brake pads have worn down completely, allowing metal components to rub directly against the brake discs. Besides reducing braking performance, it can lead to costly repairs if left unattended.

If you hear grinding when braking, it's best to have your car checked as soon as possible.

Knocking from the engine

A knocking or tapping sound coming from the engine is never something to brush off.

Depending on the cause, it could be related to low engine oil, abnormal combustion or internal engine wear. Continuing to drive without investigating the source may result in more serious engine damage.

If the knocking persists, it's a good idea to visit a workshop promptly.

Rattling underneath the car

Does your car sound like something is shaking underneath?

A rattling noise may be caused by a loose heat shield, an exhaust component or another part underneath the vehicle. While some rattles are relatively harmless, loose parts can worsen over time or even fall off if left unattended.

A quick inspection can usually identify the source before it becomes a bigger problem.

Clunking over bumps

If you hear a loud "clunk" whenever you drive over speed bumps or uneven roads, your suspension may be trying to tell you something.

Worn stabiliser links, suspension bushes or shock absorbers are common causes. Besides making your ride less comfortable, worn suspension components can affect your vehicle's handling and stability.

It's worth getting them checked before the problem worsens.

Paying attention to unusual noises and having them inspected early can save you from expensive repairs and unexpected breakdowns. If a sound is new, persistent or getting worse, don't simply turn up the radio—have your car checked by a qualified workshop.

Your ears might just save your wallet.

Frequently Asked Questions

Is it safe to keep driving if my car is making a strange noise?

It depends on the type of noise. While some sounds may be minor, persistent or worsening noises, especially from the brakes or engine, they should be inspected as soon as possible.

Why do my brakes squeal?

Brake squealing is commonly caused by worn brake pads or their built-in wear indicators. Replacing them early can help prevent further damage.

What causes a knocking sound from the engine?

Engine knocking can be caused by several factors, including low engine oil, abnormal combustion, or internal engine wear. It's best to have it diagnosed promptly.

Can a rattling noise be ignored?

Not always. Although it could simply be a loose heat shield, rattling may also indicate loose exhaust components or other parts that should be inspected.
