If you love your car and have used it for long, you are definitely familiar with the regular noise it makes, say when unlocking or starting. As such, it is quite easy for you to notice when your car noises are problematic. From clicks and squeals to knocks and pops, all vehicles make unusual noises at one time or the other. These noises might be indicating anything from simple faults to serious engine problems. Your car is a great investment, and you can't afford to take chances when it comes to keeping it healthy and functional.

Here are 4 engine noises that require immediate attention from a certified technician:


A hissing noise can be a red flag for an overheating engine or a leaking vacuum. It can also indicate a plugged catalytic converter or exhaust system. Whatever the case, make an appointment with your mechanic for immediate diagnostics and comprehensive vehicle servicing.


A knocking sound mostly indicates a problem with the ignition, which often happens when fuel ignites inside the cylinder. Ignition problems could result from a bad fuel injector, a bad distributor cap, or damaged spark plugs. It is crucial that you take the ignition problem seriously before they damage the engine.


A popping noise means there is a problem with the exhaust that requires immediate attention. They are commonly caused by leaks, particularly with the fuel injector. They could also be resulting from holes in the muffler. The best way of dealing with such noises is by working with a mechanical expert as soon as you hear the pop sound.


Squealing noises coming from your car indicates a problem with your brakes. The grinding noises are a sign of worn-out brake pads or shoes unable to keep the metal components from rubbing against each other. Make a mistake of ignoring these noises, and your entire braking system fails, making them unsafe and unreliable.
