Whether you’re running errands or on your way to work, when your car starts making strange sounds, it can be a cause for concern. Bad car noises can range from grinding to squealing and may indicate a much bigger problem. Main Auto Body, Inc. goes over four sounds that suggest your car is in need of auto repairs.

1. A Squeal or Screech When Braking

So you press your foot down on the brake pedal when a high-pitched squealing or screeching arises from your tires. When this happens, it’s likely that your brake pad is worn. And when the brake pad wears down, it can result in extra friction, which translates to excessive heat, as well as that loud screeching sound.

If you hear squealing, there’s a good chance that the brake pad indicator is rubbing against the rotor. Some manufacturers build this indication system into vehicles, so you know when the brake pads should be replaced. Either way, squealing and screeching are seldom considered an emergency. Still, you should make an appointment for brake service and inspection in the near future to prevent further damage to your car.

2. Squealing from Under the Hood

Is there a loud squealing noise emanating from the cavity under the hood of your car? It could be a loose or worn serpentine belt. The serpentine belt is a single, continuous belt that keeps your alternator, power steering pump, water pump, air conditioning compressor and other peripheral devices in your engine running. If the serpentine belt is causing a squealing noise, it could mean that it’s about to break.

When a serpentine belt snaps, you’ll be left in the lurch. In other words, your car won’t go. To prevent becoming stranded and needing to call a tow truck, it’s best to schedule an inspection as soon as possible.

3. Rumbling or Rattling Under the Car

A loud rumbling, rattling or sputtering sound coming from under your vehicle may indicate an issue with your exhaust system. Oftentimes, there’s a hole somewhere that needs to be patched up. Reattaching a loose pipe or installing a new muffler might be the solution. However, these types of sounds can also signal more costly repairs. For instance, if your catalytic converter needs to be repaired or replaced, the amount of work – and therefore cost – will be much higher.

4. Metal-on-Metal Grinding When Braking

If you step on the brake and hear a loud grinding sound, there’s a good chance that you’ve worn through your brake pads. The metal-on-metal noise you hear is the calipers grinding against the rotor. When you fail to replace your brake pads in a timely manner, the consequence is that your brakes won’t work properly. In fact, a healthy portion of vehicle crashes occur in part due to failing or degraded brakes. Therefore, if you hear grinding or other noises coming from your brakes when applied, it’s time to schedule a brake repair service.
