Car Sounds and What the Issue Could Be

An indication that your vehicle may need service is when unusual sounds arise. Below, we've provided you with a list of odd sounds you may hear from your vehicle and possible signs of what might be going on.

Squeaky Brakes

If you hear a squeaking sound coming from the brakes, this might be an indication that parts of the braking system are wearing thin. They include the brake pads and brake rotors. A technician can correct or reduce the squeaky brakes through lubrication and the replacement of the worn-out parts.

Engine Rattling

Rattling noises that originate from the engine are a result of premature ignition. This problem can be caused by several issues that may include improper ignition timing, engine overheating, and low fuel octane. Most of these problems result in the inappropriate mixing of fuel and air in the engine cylinder, causing premature ignition, which can damage various parts such as the valves, connecting tools, and pistons.

Engine Clicking

A clicking engine may be an indication that the oil levels are deficient. Here you will use a dipstick to check the oil levels. If it doesn't solve the clicking sound, your vehicle may have further issues with the upper valve train. This problem can potentially result in damage parts of the engine. It's best to have this sound addressed by one of our service experts for proper repairs.

Knocking Under the Hood

The knocking sound from under the hood will require immediate attention from a technician. This type of noise can be brought on by more significant issues, including valves, connecting rods, pistons, and other components.

Engine Squealing

There are quite a number of issues that can cause engine squealing. The most likely cause, in older vehicles, is due to loose or worn accessory belts that operate significant components such as the alternator, air conditioner compressors, and a power steering pump. For the newer vehicles, the issue may be related to the misalignment or improper tension of the serpentine belt.
