Car making a strange noise? Here's what it means

·6 min read

Strange noises from your car are often early warning signs of mechanical issues. Here's a guide to the most common car noises and what they typically mean.

Knocking or banging from the engine

Engine knocking can indicate detonation, low oil level or worn components. If accompanied by a warning light, stop immediately and check oil levels.

Squealing when braking

Squealing brakes almost always mean worn brake pads. If the squeal turns into a grinding metal-on-metal sound, the pads are completely worn — stop driving and get them replaced immediately.

Growling or humming while driving

A growl that increases with speed often points to a failing wheel bearing. Test: if the noise changes when you gently steer left or right, it's likely a wheel bearing.

Frequently asked questions

Can I keep driving with a strange noise?

Depends on the noise. Mild brake squeal can wait briefly. Loud knocking, metal-on-metal grinding or rapidly worsening sounds require an immediate stop.
