7 Common Causes of Car Noise

August 16, 2021

The last thing you want is to hear strange noises coming from your car. No matter how much you want to ignore them, your vehicle is trying to tell you something is wrong. Take a look at these seven common car noises and what they mean. 

1. Clicking Noises 

Clicking noises when trying to start your car is a telltale sign that your battery is dead or on the verge of dying. You can fix the immediate problem by using jumper cables to start your car. Afterward, bring your vehicle to your trusted mechanic to have a new battery installed. 

New Paragraph

If you hear rattling noises coming from your car, the first thing you should do is check your trunk. Oftentimes loose items in the trunk are the cause of rattling noises. If loose items are not to blame, it’s probably caused by something loose underneath the car, like your exhaust system.

3. Humming, Whirring, or Whining Noise

Humming, whiting, and whining noises can mean a lot of different things. The differential may need to be lubricated, the transmission could be failing, or a wheel bearing could be shot. The only way to know for sure is by bringing your car to a professional auto mechanic. 

4. Hissing Noises Under the Hood

If you’re hearing hissing or sizzling noises after the engine is shut off, then chances are that something in the engine bay is leaking. Look under the hood for any visible leaks, but be careful when inspecting your car since leaking fluids and air can be dangerously hot.

5. Squealing or Chirping Under the Hood

A high-pitched chirping or squealing sound coming from your car can be the result of a belt or pulley not working properly, low belt tension, or a worn-out serpentine belt. This is especially true if the noise occurs primarily during acceleration.

6. Flapping Noises Under the Hood

Do you hear flapping noises from the engine compartment? It might be due to a disintegrated or broken belt. It could also be because of something interfering with the fan. Regardless of what the cause is, be sure to check immediately or bring your car to a mechanic you trust.

7. Squealing or Screeching When Pressing on the Brakes

If it sounds like nails on a chalkboard every time you press the brake pedal, it’s likely time to have your brakes replaced. If the sound progresses to scraping or grinding, you’re in big trouble. Have your brake pads replaced immediately if they start to make noise to avoid a catastrophic accident.
