What’s That Noise? A Guide to Common Car Sounds and What They Mean

Your car has a language all its own—and when it starts talking, you should listen. Here are some common sounds and what they might be telling you:

• Squealing When Braking – Worn brake pads.
• Grinding or Growling – Potential wheel bearing or brake rotor issues.
• Clicking When Turning – Could be a CV joint going bad.
• Hissing or Whistling – Often vacuum leaks or hose problems.
• Knocking from the Engine – Dangerous; often related to fuel or ignition issues.

Ignoring these sounds can lead to more expensive repairs—or worse, safety issues.
