If your car is making an unusual noise such as clunking, squealing, grinding, or whining, it’s a sign that something isn’t working as it should. Strange noises can come from the engine, brakes, suspension, or transmission. Since noises often point to developing problems, it’s important to get them checked early before they turn into costly repairs.

What does it mean if your car is making a strange noise?

Strange noises indicate that parts of your car are under stress, worn, or failing. Different noises can point to different systems — for example, squealing may come from worn belts or brakes, while grinding may be from the gearbox or brake pads.

Common causes of unusual car noises

• Squealing – worn brake pads, slipping belts, or failing alternator
• Grinding – worn brake pads, gearbox issues, or wheel bearing failure
• Clunking or knocking – suspension or steering component wear
• Whining – power steering pump, transmission issues, or differential problems
• Hissing – vacuum leak or cooling system problem

Why do you need to fix this problem quickly?

Noises are often the first warning sign of mechanical failure. Ignoring them can lead to breakdowns, unsafe driving conditions, and higher repair bills. Fixing the issue early restores safety and prevents further damage.

How do you know when to get it checked?

Warning signs include:

• Noises that get louder with speed or acceleration
• Squealing or grinding when braking
• Clunking over bumps or when turning
• Whining when steering or shifting gears
• Any new or unusual sound that wasn’t there before

What happens during an assessment?

A mechanic will:

1. Test drive the vehicle to replicate the noise
2. Identify whether the sound comes from the engine, brakes, suspension, or transmission
3. Inspect relevant components for wear or damage
4. Check fluid levels and condition
5. Provide a diagnosis and recommend repairs

How much does it cost to fix?

The cost depends on the source of the noise. Minor fixes such as replacing a worn belt or brake pads may cost $150–$400. Larger repairs such as suspension, gearbox, or bearing replacement can range from $500–$2,500+.

Is it unsafe to drive with a strange noise?

Yes. Depending on the cause, noises can signal brake failure, suspension collapse, or engine damage. Continuing to drive without inspection may make the problem worse and unsafe. It’s best to get the noise checked immediately.
