You're driving down the asphalt, minding your own business, when suddenly, your car starts making a noise that sounds eerily similar to a helicopter taking off. What gives? Is your car possessed? Will you need to sell your soul to the devil to make it stop? Maybe. Or, it could be for any of these reasons.

Possible Reasons Behind the Noisy Car

1. Worn-out suspension

The suspension manages vehicle jump and balance and comprises various parts, including springs, shock absorbers, and control arms. When these parts are worn out, they can make noise as the car moves over bumps in the road. Additionally, worn-out suspension components can cause the car to handle poorly and may lead to accidents.

2. Lose exhaust system

The exhaust system includes the muffler, which helps reduce the engine's noise. If the muffler's loose, it can cause the car to produce a loud, rumbling sound that may resemble that of a helicopter. A loose exhaust system can also lead to decreased fuel efficiency and increased emissions.

3. Worn-out brakes

Worn-out brakes can also cause a car to sound like a helicopter. The brake pads create friction when applied, which will wear down over time. Worn-out brake pads make a noise as they rub against the brake rotors. The squealing sound a brake produces with a faulty engine resembles the loud screeching of a low-flying helicopter, scaring all around.

4. Low tire pressure

When tires are low on air, they will not be able to grip the road either, which can cause them to slip and skid when turning or stopping suddenly. Low tire pressure can also lead to decreased fuel efficiency and wear and tear on the tires. You can feel the dropping tire pressure levels when the car loses grip and hear a loud thudding sound as you press the accelerator.

5. You have a loose heat shield –

A loose heat shield is a piece of metal that protects your engine from excess heat. If it's not secured correctly, it can start to rattle and cause a sound like a helicopter blade spinning. You'll want to get this fixed ASAP before it further damages.

6. Your exhaust system is damaged -

A damaged exhaust system can cause many problems, including helicopter noise. It could be something as simple as a hole in your muffler or something more serious like a cracked exhaust manifold. In any case, you'll want to have it inspected by a professional and repaired if necessary.

7. There's something caught in your fan -

If there's something caught in your fan, like a rock or piece of debris, it can cause a rattling noise that sounds pretty close to a helicopter taking off. The good news is that this is usually an easy fix; remove the object, and you should be good to go!

8. Your idler pulley is bad -

The idler pulley keeps your drive belts tight, so they don't slip. If it starts to go wrong, it can cause a loud squealing noise that sounds like something straight out of The Twilight Zone. Replace it as soon as possible if this is the case.

How to Get Rid of Unwanted Engine Sounds? A Step-by-Step Guide

Does your engine make unwanted sounds? Do you want to get rid of them as soon as possible? If your answer is yes, this brief guide will show how to get rid of those sounds in just a few simple steps.

  1. Figure out what's causing the noise. Is it your car engine or something else? You can ignore this step if it's something else, like a rock hitting your windshield.
  2. Identify the source of the noise. Is it coming from the front or back of the car? If it's coming from the front, it might be your engine bearings. If it's coming from the back, it might be your muffler.
  3. Make a note of when you hear the noise. Does it happen when you start your car? When you're driving at high speeds? When you're turning? When you're braking?
  4. Try to replicate the conditions when you hear the noise. If you can't replicate the conditions, that's OK, but it will make troubleshooting more straightforward if you can.
  5. Once you've replicated the conditions, start your car and listen for the noise again. See if you can pinpoint where it's coming from.
  6. With this information, consult a mechanic or an expert on car sounds to diagnose the problem and find a solution.

Engine Noises: What to Look for in an Auto-Technician

What exactly should you be looking for in an auto technician when dealing with unusual engine sounds? Read on to find out!

  • Is the auto-technician ASE certified?

You should first look for whether or not the auto-technician is ASE certified. The ASE (Automotive Service Excellence) is a certification given to auto-technicians who have passed a rigorous test administered by the National Institute for Automotive Service Excellence. This certification is essential because it means the auto technician has the knowledge and skills to diagnose and fix your car correctly.

  • Does the auto technician have experience with your type of car?

Different car types require distinct repair methods and problem-solving. You'll want to ensure that the auto technician you're working with has experience with your type of car so that they can properly diagnose and fix the problem.

  • Does the auto-technician have a good reputation?

Before you take your automobile to an auto technician, it's a good idea to research and ensure that they have a good reputation. You can ask around town or look online for reviews. If you see many negative reviews, you might want to take your business elsewhere. On the other end, if you see mostly positive reviews, you can feel confident that you're in good hands.

If your car sounds more like a helicopter than a luxury vehicle, it's time to bring it into Glendale Nissan, serving Moorpark, CA. Our expert technicians will diagnose the problem and have you back on the road in no time.
