When your vehicle runs, it is never a quiet operation because something always hums in the background, but, some noises are symptoms of issues that require professional auto repair. Listen to the sounds your car makes while running, and when you hear the ones below, don’t ignore them.

5 Negative Automobile Noises & What They Mean

1. Squealing or Screeching

Front brake pads should last around 50,000 miles. When you hear a squeal or screech as you hit the brakes, it means there's something wrong with the brake pads or rotors. The pads are worn and need replacement before they cause further damage to the rotors. An auto repair expert can install new pads and check the rotors for warping.

A high-pitched squeal can sometimes indicate a failing axle or wheel bearing, or loose or worn drive belts, so have these checked immediately.

2. Grinding or Scraping

A grinding sound when you brake may signal badly damaged rotors and calipers. It happens when you ignore the squealing noise you've heard before—the pads have worn down, causing the rotors to rub against the caliper, a metal clamp component that squeezes your breaks. Eventually, this can lead to brake failure, so opt for auto repairs immediately.  

3. Rattling

If you notice a rattling sound akin to coins inside a dryer, it's a telltale sign that your wheel isn't secure. There's a loose lug nut in the hubcap that's causing the racket. However, it's also a symptom of a bigger problem—a damaged catalytic converter. It transforms toxic emissions into less harmful substances, so the converter is essential to your exhaust system.

4. Roaring or Rumbling

A loud roaring or rumbling sound coming from under your car is another indicator of exhaust system problems. You may have a leak or crack somewhere in the exhaust manifold, pipes, or muffler. While it's easy to dismiss the noise as normal, avoid doing so since it's dangerous. A leak in the exhaust system means the toxic carbon monoxide is venting inside the cabin, not away from it.

5. Clicking or Tapping

Have you heard a rhythmic tapping or banging under your hood? If you have, there's likely an issue with the valves, pistons, or connecting rods. But if it sounds more metallic, then you may have a low engine oil level or problems with the pressure or pump.
