8 Car Noises You Need to Be Concerned About


1. A Squeaking Noises

If you hear a squeaking car noise every time you turn the steering wheel, there's a good chance that your car needs some power steering fluid. This is a hydraulic fluid that helps you turn the steering wheel easily. The fluid becomes less effective over time due to wear and tear.

So, if you hear a squeaking noise when you turn the wheel, don't ignore it and top off your power steering fluid. It's a quick and easy fix that will save you a lot of headaches down the road.

2.   A Screeching Noise When You Brake

The screeching noise indicates a problem with the brake pads, which probably need to be replaced. The pads create friction that stops your car when you hit the brakes.

If you get routine maintenance on your car, your mechanic will catch the problem early enough, and they may be able just to replace the pads rather than the entire braking system - which can save you quite a bit of money!

3.   A Knocking Noise When Turning the Steering

If you hear a knocking noise when you turn the steering wheel, there's likely something wrong with the steering rack. If this problem is ignored, it could eventually lead to losing control of the vehicle while driving.

4.   A Whistling Noise When You Accelerate

Whistling is usually an indication of a problem with the exhaust system. It could be something as simple as a loose connector, but it could also signify a more serious issue, like a hole in the muffler.

In any case, it's best to have it checked out by a professional so they can determine the cause and make the necessary repairs.

5.   A Rattling Noise When The Engine Is Idling

If you hear a rattling noise from the engine bay when the car is idling, it could signify that the engine is misfiring. This can happen if the spark plugs are dirty or worn out, the ignition coils fail, or there's an issue with the fuel injectors. If you're hearing this noise, it's best to take the car to a mechanic and have them diagnose the problem.

6.   A Rumbling Noise Coming from Underneath the Car

The rumbling noise from underneath indicates a problem with your exhaust system. The exhaust system includes the muffler, catalytic converter, and other parts that help reduce noise and pollution. If one of these parts malfunctions, your car will rumble!

If you hear this noise, try to get to a mechanic as soon as possible. Depending on the severity of the problem, you may need to replace your muffler. But if the issue is with your catalytic converter, you'll need to replace that - which can be quite expensive.

7.   A Knocking Noise When You Accelerate

If you hear a knocking noise every time you step on the gas pedal, your engine may be experiencing "knocking." Knocking occurs when the air/fuel mixture in the cylinders isn't being burned evenly. It can damage your engine over time if it's not fixed, so it's something you want to take care of immediately! The most successful method to fix knocking is by bringing your vehicle to a mechanic and having them change your engine's timing. It's usually a quick, easy fix that won't cost too much.

8.   A Hissing Noise Coming from Under the Hood

Another common problem is a hissing noise from under your car's hood! The most likely culprit is a leak in one of your hoses or lines - possibly even in the radiator itself. If you hear this noise, you must take your car to a mechanic as soon as possible. A leaky hose or line can quickly become a much bigger problem if it's not fixed promptly. A leak like this can quickly lead to engine problems, so it's important to take care of it as soon as possible!


Anytime your car starts making strange noises, it's normal to be concerned - especially if you're not sure what those noises mean or how serious they might be. However, by familiarizing yourself with some common noises cars make (and what they could tell), you can rest assured knowing that you'll be able to diagnose properly (and solve!) any matter how big or small!
