Car Noises You Should Never Ignore

Rattling Sounds in Your Car

A rattling sound from your engine can be unnerving, but it doesn't always signal a major problem. Here are some common causes:

• Loose engine parts: Heat shields, belts, or mounts may loosen over time, creating a rattling noise while driving.
• Exhaust leaks: Cracks or holes in your exhaust system can cause air to escape, producing a rattling or clanging sound.

Both can impact engine efficiency or fuel economy if left unchecked.

Grinding or Growling Noises

A grinding or growling sound often points to worn brake pads. Metal-on-metal contact reduces braking performance and can damage your rotors if ignored--making this one of the most urgent noises to note.

A Hissing Sound

If you hear a hissing noise coming from under the hood, it's probably not a snake, but it's still worth paying attention to. Common causes include:

• Vacuum leaks affecting engine performance and fuel efficiency
• Damaged exhaust systems impacting efficiency
• Coolant leaks which can cause engine overheating

Squealing

• Brake squeal: This is your brake pads signaling they're wearing down. Ignoring it can damage rotors.
• Belt squeal: If the squeal comes from under the hood, worn or stretched belts are often to blame. Replacing them on time prevents breakdowns and keeps your engine running smoothly.

Knocking

Engine knocking can indicate low fluids or worn rod bearings. Catching these sounds early can save you from costly engine repairs.

Clicking While Turning

If your front-wheel-drive or all-wheel-drive vehicle clicks while turning but not when driving straight, the constant velocity (CV) joints may need attention.

Ticking

• Tire ticks: Small debris like gravel can cause a temporary ticking sound.
• Engine ticks: Persistent ticking while idling may indicate low oil, which can prevent proper lubrication of engine components and cause serious damage.

Honourable Mention:  Keep Your Tires Inflated

Low tire pressure can lead to unusual noises, reduced fuel efficiency, uneven tread wear, and extra stress on your engine. Check your tire pressure monthly, and visit our Tire Shop for the right tires, brands, and packages for your vehicle.
