9 Car Noises That Shouldn't Be Neglected

Key Takeaways:

  • If you hear a high-pitched squealing noise when you accelerate, it’s likely coming from your drive belt.
  • Hissing noises are heard due to a leak in the cooling system.
  • An issue usually causes whirring noises with the transmission, specifically the input shaft bearing.
  • Rumbling noises come from under the hood due to an issue with the engine’s pulleys.
  • If you are hearing unusual car noises coming from your car, don’t ignore them! These noises are an indication of a severe problem.

Most drivers are familiar with the standard array of car noises – the engine, the tires on the road, and wind noise. But what about those other strange sounds your car sometimes makes? Many of them can be harmless and just a part of routine car operation, but some can be signs that something needs to be fixed.

Let’s discuss some unusual car noises that shouldn’t be neglected while also providing you with tips on troubleshooting them.

Unusual Car Noises, What Causes Them, And How to Troubleshoot Them?

1. High-Pitched Squealing

If you hear a high-pitched squealing noise when you accelerate, it’s likely coming from your drive belt. The drive belt is a long, flat belt that helps to power the engine accessories like the air conditioning compressor, power steering pump, and alternator.

If the drive belt is damaged, it can cause this squealing noise. A dealership can fix this issue by tightening or replacing the drive belt.

2. Rattling Noise When You Start the Car

When you start your car, hearing a rattling noise can mean having a loose heat shield. Heat shields are metal and designed to protect the engine from excessive heat.

If a heat shield is loose, it can rattle against the engine or exhaust system, causing this noise. This issue can be rectified by tightening the bolts that hold the heat shield in place or replacing it if it’s damaged.

3. Hissing Noise While the Car Is Running

Hissing noises are heard due to a leak in the cooling system. The coolant in the system helps keep the engine from overheating, so if there’s a leak, it can cause the engine to overheat.

A servicing technician can check for leaks and repair them as needed. They may also need to refill the coolant system if there’s been a significant fluid loss.

4. Big Booms from The Rear of The Car

Loud booms or bangs coming from the car’s rear may be due to a problem with the exhaust system. The muffler or one of the pipes could have a hole or be loose. Have a car maintenance technician inspect the exhaust system and make repairs as needed. They’ll also be able to tell you if the noise is coming from something else, such as a loose object in the trunk.

5. Clicking Noise When Turning

A clicking noise when you turn the steering wheel is usually due to low-power steering fluid. When there’s not enough fluid, it can cause the parts of the system to grind together and make noise.

You’ll need to add power steering fluid to the reservoir to fix this. If the noise persists, have a technician check the power steering system for leaks.

6. Occasional Rattling Noises

Several things could cause a rattling noise, so it’s hard to say what the problem is without hearing it first. It could be something as simple as a loose change in the glove compartment or something more severe like an exhaust leak.

If the rattling noise comes from under the hood, it could signify that something is loose and needs tightening. Check all the nuts and bolts under the hood to see if anything is loose. If you can’t find the noise source, have a technician inspect them.

7. Squeaking Noise

You may occasionally hear unusual car noises like squeaking when you press the brakes. Worn-out brake pads usually cause it. When the pads wear down, they start to make a squeaking sound. It is a warning that they need to be replaced.

If you ignore the noise and don’t replace the pads, eventually, they’ll wear down so much that they’ll start to damage the rotors. Replacing the pads is a relatively inexpensive repair. Still, if you wait too long and damage the rotors, you’ll also need to replace them.

8. Whirring Noise as You Accelerate

Other unusual car noises include whirring noises when you accelerate. It’s usually caused by an issue with the transmission, specifically the input shaft bearing. The input shaft bearing supports the input shaft, which is what the transmission gears are attached to.

If the input shaft bearing fails, it can cause the input shaft to wobble. It causes the transmission gears to grind against each other, which makes a whirring noise.

Ignoring the noise and not getting the input shaft bearing replaced eventually makes it fail. It will damage the transmission and will be much more expensive to repair.

9. Rumbling Noise

You might also hear a rumbling noise coming from under the hood, which is an issue with the engine’s pulleys. The pulleys are what the belts are wrapped around. If one of the pulleys is worn out, it can cause the belt to slip or come off entirely.

If the belt slips, it will cause the engine to run less efficiently. It will lead to decreased performance and fuel economy. If the belt comes off entirely, it can cause severe damage to the engine.
