Car Sounds and What the Issue Could Be

Your car should generally drive smoothly and quietly. But sometimes, you may notice a sound that doesn't seem to be quite right. Unusual sounds may be the first indication of a problem with your car, whether it's the brakes, engine, or another component under the hood. No matter what kind of sound your car is making, it's best to contact our expert technicians to schedule an appointment to inspect the car. Meanwhile, we provide a guide to help you understand what may be the cause of your car's strange sounds.

Squeaky Brakes 

Each day, the brakes are subjected to considerable force and pressure when driving your car. The brakes ultimately wear out over time with extensive use. If you notice the brakes squeaking when you stop the car, it may be because the brake's components, such as the brake pads, are wearing thin. The brake pads should be replaced if necessary. Otherwise, they can cause the metal parts on the brakes to rub against each other, which in turn can cause considerable damage. A mechanic can lubricate and service the brakes, and also replace worn materials if necessary.

Engine Rattling 

A rattling sound coming from the engine can usually be traced to improper firing of the piston called pre-detonation or pre-ignition. When this happens, an ignition occurs before the piston gets to the top of its stroke. The premature ignition can cause damage to the connecting rods, valves, and pistons. The condition can be caused by the engine overheating or improper fuel octane.

Engine Clicking 

The engine may make clicking sounds if there is a problem in the upper valvetrain, such as insufficient amounts of oil. Worn or damaged parts and excessive valve lash can also cause clicking sounds from the engine.

Knocking From under the Hood 

If you notice knocking sounds coming from below the hood of your car, it might mean that there are problems with some of the car's major components such as the pistons, connecting rods, or valves. This issue requires a technician's immediate attention to avoid major damage.

Engine Squealing

There can be several reasons why the engine makes squealing noises. One of the most common causes is when a roller bearing fails on one of the engine's accessories, such as the idle bearing, water pump, or alternator. This is especially the case with older vehicles. Newer vehicles may need to be checked for signs of damage to the serpentine belt, which can cause the engine to make squealing noises if it is worn out or becomes loose.
