Car Sounds and What the Issue Could Be

Car sounds can be mysterious. Noise coming from the engine or brakes, for instance, may indicate more serious issues. Anytime you hear a knocking, squealing, clicking, rattling, or squeaking noise, it's time to give your car a closer look to determine the noise source.

Squeaky Brakes

If you hear squeaking when you step on the brakes, it's time to pinpoint the cause. Squeaking brakes can be caused by one of many loose components in the braking system, including hoses, rotors, and calipers. The parts can produce a squeaking sound when they start to vibrate. The brake components may also need to be adjusted, lubricated, or cleaned. Worn brake pads can cause squeaking when the metal component of the brakes becomes exposed. Humidity, rain, and snow can also cause a squeaky brake noise.

Engine Rattling

Rattling noises coming from the engine are typically caused by a condition called premature ignition, or "pre-ignition." The rattling starts when air and fuel mix in the engine cylinder improperly, causing multiple flame fronts. The early ignition can cause problems for other engine components if the problem is not addressed. A low volume of oil is one possible cause of engine rattling, as well as problems with the knock sensor, computer, or EGR valve.

Engine Clicking

Engine clicking sounds can also come from various sources. Rods can create a ticking sound when the bearing attached fails. Insufficient amounts of oil can also create ticking noises in the engine. If you have this problem, you might also notice that the engine seems to be warmer than usual and is prone to overheating. Damaged seals and gaskets are other issues that can trigger engine clicking. Poor components, including bad reciprocating components, can produce odd clicking noises.

Knocking Under the Hood

Noises coming from under the hood are typically indications of a more serious problem. There are two likely reasons for knocking under the hood. One is potentially due to a worn crankshaft, and the other is a issue with the transmission. Both can lead to more extensive mechanical trouble if not addressed.

Engine Squealing

Squealing noises in the engine may be a result of a roller bearing that breaks on an accessory. The serpentine belt can also cause squealing when it is misaligned, worn down from friction or has improper tension.
