In this article, we’ll cover 7 common car noises and what they typically mean, helping you know when it’s time to visit an auto repair shop.
1. Squealing Brakes
Common search terms:
“Why do my brakes squeal?”
“Squeaking noise when braking”
“Car makes noise when I stop”
What it means: If your car squeals when you hit the brakes, the brake pads are likely worn out. Many modern brake pads have built-in wear indicators that make this sound as an early warning.
Why it matters: Worn-out brake pads can damage the rotors, leading to more expensive repairs and compromised safety.
2. Clunking Noise While Driving
Common search terms:
“Clunking noise under car”
“Car makes clunk noise over bumps”
What it means: This could be a suspension issue. Bad sway bar links, control arms, or struts often cause a loud clunking sound, especially when turning or going over potholes.
Fix it fast: Driving with worn suspension can affect handling and tire wear.
3. Grinding When Shifting Gears
Common search terms:
“Grinding sound when shifting”
“Transmission making noise”
What it means: For manual cars, the clutch may not be disengaging fully. In automatics, grinding could mean transmission trouble or low fluid.
Act quickly: Transmission repairs can be costly, early attention may prevent a full rebuild.
4. Clicking Noise When Turning
Common search terms:
“Clicking noise front wheel”
“Car clicks when I turn”
What it means: Likely a failing CV joint or axle. If it only happens when turning, it’s almost certainly CV-related.
Why it’s urgent: Left unchecked, a worn CV joint can fail entirely and leave you stranded.
5. Hissing From the Engine
Common search terms:
“Hissing noise under hood”
“Engine hissing sound”
What it means: This often points to a vacuum leak, a coolant leak hitting a hot surface, or a damaged hose.
Don’t delay: Overheating or poor engine performance can result if the issue isn’t fixed quickly.
6. Rattling Under the Vehicle
Common search terms:
“Rattling under car”
“Car makes noise when idling”
What it means: You might have a loose exhaust heat shield, damaged catalytic converter, or even a loose muffler bracket.
Why it matters: Exhaust issues affect emissions, performance, and fuel economy.
7. Loud Roaring or Exhaust Sound
Common search terms:
“Loud exhaust noise suddenly”
“Car sounds louder than normal”
What it means: A sudden increase in engine volume often signals an exhaust leak, possibly a broken muffler or exhaust pipe.
Be cautious: Exhaust leaks can allow harmful gases into your cabin. Don’t wait to get this checked out.
