Car Sounds and What the Issue Could Be

When hearing unusual sounds, it's best to identify the issue to get a better understanding of what your car is telling you. Some car sounds may be linked to underlying issues. Here we list some common abnormal sounds and what they are indicating.

Squeaky Brakes

Squeaky brakes are linked to worn-out brake pads and rotors. When the rotors wear down, the surface becomes smoother and causes the brake pads to screech or squeal when sliding against the surface. This sound may be indicating a need for repair or replacement of brake components.

Engine Rattling

An engine rattle can occur during acceleration. There could be various problems, such as a loose mechanical part connected to the engine, low-octane fuel, an overheated engine, or an ignition system defect.

Engine Clicking

The main cause of engine ticking or clicking could be a valve malfunction. The valves are designed to open and close repeatedly, but they create excessive clicking sounds due to malfunctions. Clicking sounds could also signify low oil levels. Check the oil levels in the engine and restore it to the recommended levels if necessary. If the sound persists, our service experts can help identify the issue.

Knocking From Under the Hood

While driving or running the engine, you may hear sounds like large objects being knocked together under the hood. You may need a higher octane fuel to prevent the fuel from detonating too early. In other cases, an incorrect air-fuel mixture causes the knocks from premature ignition.

Engine Squealing

A high-pitched squealing sound is common when braking, but it can also occur under the hood. One reason could be a worn-down serpentine belt that causes the alternator or power steering pump to malfunction. A steering component of the engine that is excessively dry could squeal when you turn the steering wheel.
