Does your vehicle make funny noises sometimes? Do you know what they indicate? Many people don’t, and that can lead to big trouble down the road. Many mechanical problems can cause unusual sounds, some of which can be serious. Lakeland Hyundai will discuss some of the most common car noises and what they could mean. If your car is making these sounds, taking it in for a diagnostic as soon as possible is essential!

10 Common Car Noises That Could Mean Trouble

1. A Grinding Noise When You Brake

If your car makes a grinding noise while braking, it could signify that the brake pads are worn out and must be replaced. There could even be a more severe problem, such as a problem with your brake calipers or rotors. If your car makes this noise, it’s essential to have your brakes checked by a professional as soon as possible.

2. Clicking When You Turn the Steering Wheel

A clicking noise when you turn the steering wheel is likely due to a problem with your CV joint. The CV joint allows the wheels to turn while the car is moving; if it’s damaged, it can cause a clicking noise. It is usually not a severe problem, but it must be fixed by a professional.

3. Rattling Under the Hood

If you hear a rattling noise from under your car’s hood, there could be loose parts in the engine or low oil levels. That’s why it’s essential to have your vehicle checked by a mechanic to determine the cause.

4. Hissing From the Engine Compartment

If you hear a hissing sound coming from the engine, it’s likely due to a coolant leak. Coolant keeps your engine cool, so if there’s a leak, it can cause your engine to overheat. It is a severe problem that should be fixed by an experienced mechanic as soon as possible.

5. Knocking from the Engine

If you hear knocking from the engine, it’s likely due to low or dirty oil. Low oil levels may damage your machine, so it’s essential to check your oil level regularly and top off as needed. Dirty oil can also cause knocking, so it’s necessary to have your oil changed regularly.

6. Humming From the Engine Compartment

If you hear humming from under the hood, it’s likely due to a problem with the alternator belt. The alternator belt powers the alternator, which charges the battery. The strap makes a humming noise when it is loose or worn out. It is usually not a serious problem but should be fixed by a qualified mechanic.

7. A Grinding Noise While Turning Steering Wheel

The power steering system contains hydraulic fluid that assists you in turning the steering wheel. A leak in the system can lower the fluid level, resulting in a grinding noise while turning the wheel.

8. A Clicking Noise During Ignition

A clicking noise during ignition is often linked to a failing battery. The battery provides power to start your car’s engine. If it is not working correctly, it can cause this clicking sound.

9. A Howling or Whining Sound

Sometimes your car may make a howling sound accompanied by a whining noise.

If the sound changes as you turn left, right, and then back again, it’s probable that your front-wheel bearings are faulty. And a gradually increasing, constant howl indicates that the rear-wheel bearings need repair or replacement. But if you have rear-wheel drive and the noise levels increase as you speed up, your differential could be leaking fluid. Get it fixed immediately by a mechanic.

10. Rhythmic Clunking From Under the Hood

If you hear a clunking noise that seems to be coming from the engine, it may mean that your car is low on oil. It is your engine’s way of telling you it needs more oil. Ensure the oil level is adequately filled by checking the dipstick. If it is low, add a quart of the same-weight oil and see if the noise goes away. If it does, drive for a day or two and recheck the level to identify a possible leak. If the oil level is low, get it fixed by a mechanic ASAP.

Another possibility could be a valve that isn’t closing correctly. It is usually more noticeable when the engine is first started after sitting for a while, like overnight. The sound may go away as the engine warms up, but if it doesn’t and the car has high mileage (say, over 100,000 miles), it’s probably time for an overhaul or replacement.
