Early Warning Signs: 5 Engine Noises that Car Owners Shouldn’t Ignore

Owning a new car is an exciting experience, but it also comes with the responsibility of taking good care of your investment. One crucial aspect of car maintenance is paying attention to the various sounds your car makes. Some engine noises may seem harmless, but they are in fact warning signs that something is amiss under the hood. We’ll discuss the top 5 car engine noises that new car owners should never ignore and why they require immediate action.


If you hear a knocking noise coming from your engine, it's vital not to dismiss it as a minor annoyance. These sounds are often indicative of a problem with the engine's combustion process, most likely the cylinders misfiring. Ignoring this noise can lead to severe engine damage, reduced fuel efficiency, and costly repairs. Visit your mechanic promptly to diagnose and fix the issue.

Hissing or Sizzling

Hissing or sizzling sounds under the hood may be signs of a coolant or exhaust system leak. These leaks can result in engine overheating, loss of power, or even carbon monoxide exposure, which poses a significant safety hazard. As a new car owner, never ignore these sounds and have your car inspected immediately to prevent further damage and ensure safety on the road.

Squealing or Screeching

A high-pitched squealing or screeching noise, particularly when you start your car or while turning the steering wheel, may indicate issues with the serpentine belt or other driving belts. Over time, these belts wear out and can snap, causing engine components to fail. Replacing a worn belt is a relatively inexpensive repair compared to potential damage that can occur if you neglect this noise.

Squealing may also come from the brakes. If squealing comes from pressing on the brake pedal, this means that the pad is worn out. This is a sign that the brakes can break down at any moment and warrants a replacement as soon as possible. After all, the cost of replacing these components is negligible compared to the cost that comes from any potential accidents that may happen on the road.

Rumbling or Growling

If your car's exhaust system emits a deep rumbling or growling noise, it's often a sign of a problem with the muffler, catalytic converter, or exhaust pipes. Ignoring this noise may lead to decreased engine performance, increased emissions, and a failed emissions test. Get your car to a professional for an exhaust system inspection and necessary repairs to maintain your vehicle's efficiency and environmental compliance.

Whining or Grinding

When shifting gears, if you hear a whining or grinding noise, it's a clear indication of transmission issues. Transmission problems can be costly to fix if not addressed promptly. Neglecting these noises can lead to unreliable shifting, decreased fuel efficiency, and ultimately a complete transmission failure. Seek professional advice and inspection if you hear these sounds.

In conclusion, as a new car owner, understanding and addressing these engine noises promptly is crucial to keep your vehicle in top shape and ensure your safety on the road. Ignoring these sounds may lead to more extensive, costly repairs down the line and jeopardize your vehicle's overall performance. Regular maintenance and inspections by a qualified mechanic can help prevent such issues, ensuring your new car remains reliable and runs smoothly for years to come.
