What’s That Weird Noise Coming from Your Engine?
At Millennium Auto Group, we know your car isn’t just a machine—it’s your daily sidekick, getting you where you need to go. But when your engine starts making odd noises, it can be pretty unsettling. Don’t ignore them! Your car is trying to tell you something. Let’s break down the eight most common engine noises and what they mean so you can stay ahead of potential problems.
The Whiny Soundtrack
Ever heard a high-pitched whine under the hood? It’s not your car singing—it’s likely a power steering pump issue, a failing alternator, or a loose belt. Start by checking your fluid levels and inspecting your belts for wear. If the noise sticks around, it’s time to call in the pros.
That Annoying Clicking or Tapping
A repetitive clicking or tapping sound usually means low oil. Your engine needs proper lubrication, and if it’s not getting enough, parts will start making noise. Check your oil level, and if it’s fine but the sound persists, a mechanic should take a look before it turns into a bigger issue.
The Grinding Nightmare
Grinding noises are a big red flag. If it happens when you shift gears, it could mean trouble with the clutch or transmission. If you hear grinding when you start the engine, your starter motor might be struggling. Either way, don’t wait—get it checked ASAP.
That Screeching Squeal
A loud squeal when you start the car or hit the gas usually points to a slipping belt. Over time, belts wear down and lose tension, causing that unbearable noise. Give your belts a once-over and replace any that look cracked or worn.
The Mysterious Knocking or Pinging
If your engine sounds like it’s knocking on a door, it could be experiencing detonation—uneven fuel ignition inside the cylinders. This can happen with low-quality fuel or if there’s an issue with ignition timing. Try filling up with premium fuel, and if the sound persists, have a mechanic check things out.

That Hissing Sound You Can’t Ignore
Hissing from under the hood is never a good sign. It could mean a coolant or vacuum leak. Check your coolant levels and inspect hoses for cracks or leaks. If you see steam or your car is overheating, don’t wait—get it fixed before you’re left stranded.
The Rattling Mystery
A rattling sound could be caused by a loose bolt, heat shield, or exhaust component. If you hear it, check under the car and around the engine bay. If you’re not sure what’s loose, have a pro take a look before it becomes a bigger issue.
Grinding While Driving or Turning? Uh-Oh.
If your car makes a grinding noise when you drive or turn, your wheel bearings might be on their last leg. These little guys keep your wheels spinning smoothly, so if they fail, things can get dangerous fast. Get them checked before they cause bigger (and pricier) problems.
