Diagnose Your Car Sounds

Car Sounds and What the Issue Could Be

Subaru models are built to last. In fact, 97% of Subaru vehicles sold in the last 10 years are still on the road today.* To keep your vehicle running for many years to come it's important to keep up with routine maintenance that is needed as a result of the wear and tear of daily driving. Odd sounds are something you may notice when there is a malfunction that a Subaru certified technician should address. Here are some clues that can help you diagnose some of the most common automobile issues.

Squeaky Brakes

Your brakes are subjected to a lot of stress. Over time they will wear down from daily use. If there is an issue, you may notice a squeaking noise when you step on the brake pedal while in motion. That's an indication that the pads or rotors may be excessively worn and are in need of replacement. Occasionally after you have new brake pads installed you may hear a squeaking noise. New brake pads have metal fibers and are coated with protective elements that can cause this. Normal driving and braking will typically wear these areas down quickly and the noise should disappear. If you continue to hear squeaking, contact our team of certified Subaru service professionals for a complete inspection.

Engine Rattling

When a rattling sound originates from your engine, you could be experiencing a premature ignition or pre-detonation. You could also have an overheated engine or poor fuel octane. When air and fuel mix together at an improper ratio, you can have a whole host of ignition issues that result in engine rattling. If you don't have this taken care of right away, problems can occur with your engine valves, pistons, and connecting rods.

Engine Clicking

A clicking sound coming from your engine can mean a few things. When your vehicle is on the fuel injectors quickly open and close to let fuel enter the internal combustion chamber. A clicking-type sound can occur when that happens, but this is part of the normal operation of your vehicle. However, clicking, ticking or tapping sounds when your vehicle is running can also mean a problem. The first thing to check is the level of your oil. If you're not low on oil, your vehicle may have an issue with bad reciprocating components, rod knock or issues with the valve train. It's always a good idea to have your vehicle checked just in case there is a problem to prevent any further damage to the engine.

Knocking Under the Hood

When you hear a loud knocking sound from your engine, visit our service department right away. You could have a serious problem going on with your valves, pistons, or connecting rods. Knocking under the hood could also be a sign of transmission problems or a worn crankshaft. Continuing to drive your vehicle could cause irreversible damage to your engine.

Engine Squealing

This noise is generally the result of a loose or worn out belt. If you hear this sound when you accelerate, it's likely the serpentine belt. In newer models this belt handles everything from your power steering pump to the cooling fan, air conditioning compressor and more. In older models there are several belts that handle each of these items separately that could be the issue. The noise can also come from a failing alternator. If a squealing sound can be heard when you turn the steering wheel, you may have an issue with the steering system. Due to the number of possible issues, it's best to have a full inspection and diagnostic done to determine the exact cause and to prevent any damage to your vehicle.

It's always important to have timely service performed to keep your vehicle running smoothly and safely. If you notice a strange sound coming from your car, contact us to schedule an appointment with the Subaru factory certified technicians at our auto repair center in Phoenix, AZ.
