Cars rarely fail without warning. Most of the time, they try to tell you something first, usually through noise. The problem is that many drivers either ignore these sounds or misunderstand them.

Here are some of the most common car noises UK drivers hear, what they usually mean, and when you should take action.

1. Squealing when you brake
A high pitched squeal when braking is often caused by worn brake pads. Many brake pads are designed to make this noise as a warning.

What to do:
Have your brakes checked soon. If left too long, it can lead to more expensive damage.

2. Grinding sound when braking
This is more serious than a squeal. Grinding usually means the brake pads are fully worn down, and metal is rubbing against metal.

What to do:
Avoid driving if possible and get the car checked straight away.

3. Clicking when turning
A clicking or tapping noise when turning, especially at low speed, is often linked to worn CV joints, usually in front wheel drive cars.

What to do:
Get it checked soon. If it fails, you could lose drive to the wheels.

4. Knocking from the engine
A knocking or pinking sound from the engine can be caused by incorrect fuel, carbon build up, or engine timing issues.

What to do:
Use the correct fuel for your car and get it checked if the noise continues.

5. Hissing under the bonnet
A hissing noise could mean a leak, often from the cooling system or a vacuum hose. It may also be steam from an overheating engine.

What to do:
Pull over safely and let the engine cool before checking. Do not open the coolant cap while hot.

6. Rattling underneath the car
This is often something loose, such as part of the exhaust system or a heat shield.

What to do:
Have it looked at. It may be a simple fix, but it can get worse if ignored.

7. Whining when accelerating
A whining noise that changes with speed can point to gearbox issues, especially in manual cars, or worn bearings.

What to do:
Get it checked early. Gearbox repairs can become expensive if delayed.

8. Clunk when changing gear
A clunking sound when shifting gears may be caused by worn mounts, drivetrain parts, or suspension issues.

What to do:
Book an inspection to prevent further damage.

9. Squeak over bumps
This is often linked to worn suspension parts such as bushes or shock absorbers.

What to do:
Not always urgent, but worth checking for safety and comfort.

10. Ticking noise after switching off the engine
This is usually normal. It is often just metal parts cooling down and contracting.

What to do:
No action needed unless the sound is very loud or unusual.

Final thought
Not every noise means a serious problem, but very few should be ignored. Acting early can save you money and help you avoid being stuck at the roadside.

If you are ever unsure, it is always safer to get your car checked or make sure you have reliable breakdown cover in place.
