Over time, drivers develop a relationship with their vehicle, which allows them to notice when it is operating differently than usual. For example, if your car is emitting an unusual sound while on the road, it likely speaks to a loose or malfunctioning part. Seek auto repairs as soon as possible, especially if you hear the following.

5 Sounds That Require Auto Repair

1. Squealing

A high-pitched squealing sound usually means one of two problems. If you hear it when pressing the brakes, it is likely worn-out brake pads. When these parts become too thin, it makes it harder to stop at high speeds, putting you at a higher risk for accidents.

If the noise appears when you are accelerating, it points to a faulty fan belt. Although you can quickly tighten a loose fan belt, a worn-out one can reduce the efficiency of your power steering, as well as damage engine components.

2. Grinding

You’ll hear grinding sounds eventually if you skip out on replacing worn-out brake pads. It’s the noise of calipers and rotors rubbing against each other without the pads.

However, if the sound comes out of the hood, it means trouble in the engine bay. Since it could be the engine, pulleys, alternator, power steering pumps, or the compressor, have an auto repair technician diagnose it.

3. Hissing

A hissing or sizzling sound under the hood indicates a leak somewhere in the engine bay because of damaged hoses. Rubber hoses are essential to convey liquids and air throughout the vehicle. However, they turn brittle over time, eventually cracking, causing the contents to fall on hot surfaces. If left unchecked, leaks can cause further trouble.   

4. Rattling or Rumbling

Noises akin to rattling or rumbling under the car point to problems with the exhaust system. Depending on what you hear, it may be a failing catalytic converter, cracked manifold, corroded pipe, or broken muffler that’s causing the racket. A malfunctioning exhaust system reduces fuel economy and pollutes the environment. It could also put you at risk for carbon monoxide poisoning as toxic gases get vented inside the cabin instead of outside.

5. Groaning

Do you notice strange sounds whenever you make a turn? A groaning noise coupled with a stiff steering wheel indicates problems in the power-steering system that may affect vehicle control if left unchecked.

Alternatively, clunking or knocking sounds as you turn suggest there’s a problem with the suspension system's tie rods, ball joints, sway bar links, shocks, or struts.
