Hearing odd sounds coming from your car? You’re not alone. Weird car noises are one of the top reasons people visit a repair shop—and figuring out what they mean early on can help you avoid bigger, more expensive problems later. Let’s break down some of the most frequent noises and what they might mean for your vehicle’s health.
Rattling Sounds
“Why is my car making a rattling noise?”
That’s one of the most common questions mechanics hear. Rattling can come from various places under your hood or chassis, and often points to loose parts. You may be dealing with:
- A loose heat shield
- A damaged muffler or exhaust system
- Worn-out suspension components
- Loose engine mounts
Rattling sounds usually get worse as your car vibrates or speeds up. If the noise is consistent or starts happening more often, it’s a good idea to have a professional take a look.
Squealing or Screeching
A high-pitched squeal, especially when braking, often means your brake pads are worn and need replacement. In some cases, belts under the hood (like the serpentine belt) may also squeal if they’re loose or cracking.
Clicking or Popping Noises When Turning
If your car makes noise when turning, especially a clicking sound, it might be a sign of worn CV joints. These are critical parts of your front axle system and help your wheels turn with the suspension. Ignoring the issue could lead to more serious—and expensive—damage.
Other possible causes include:
- Low power steering fluid
- Faulty ball joints
- Damaged control arm bushings
Hissing or Whistling
A hissing sound coming from the engine could point to a vacuum leak, a cracked hose, or even a coolant leak. If you hear hissing right after turning off the engine, it may mean the system is overheating or leaking pressure somewhere it shouldn’t be.
Grinding or Growling
Grinding often signals trouble with your brakes, especially if it happens when you step on the pedal. It could mean your brake pads are completely worn and metal is now contacting metal—something you don’t want to ignore. Growling noises can also come from a failing wheel bearing or transmission issue.
