You know your vehicle better than anyone. So when it starts making a strange noise—something that wasn’t there yesterday—it’s hard not to feel a little uneasy. Is it something minor, or is it a warning sign of a bigger problem?
At Service Plus Automotive, we get these questions every day from local drivers who just want to keep their families safe and their cars running right. Unusual sounds can be your car’s way of telling you something is off—and catching those issues early can save you time, money, and stress down the line.
Here’s a breakdown of the most common vehicle noises, what they might mean, and when it’s time to bring your car in.
1. Squealing When You Brake
What it sounds like: A high-pitched squeal that happens when you press the brake pedal.
Possible issue: Worn-out brake pads. Most brake pads have a built-in indicator that squeals when they’re nearing the end of their life.
What to do: Schedule a brake inspection right away. Continuing to drive on worn pads can damage your rotors and lead to more expensive repairs.
2. Grinding When You Stop
What it sounds like: A harsh metal-on-metal grinding noise during braking.
Possible issue: Your brake pads may be completely worn down, allowing the metal caliper to grind against the rotor.
What to do: This is serious. Pull over if needed and call us. Driving with this noise is dangerous and can severely damage your brake system.
3. Clicking While Turning
What it sounds like: A clicking or popping noise when making sharp turns.
Possible issue: A failing CV (constant velocity) joint or axle.
What to do: This needs attention before it leads to a breakdown. Our technicians can diagnose and replace worn CV joints before they leave you stranded.
4. Hissing From Under the Hood
What it sounds like: A constant hissing, especially when the engine is hot.
Possible issue: Could be a coolant or vacuum leak. In some cases, it’s steam escaping from an overheating radiator.
What to do: Pop the hood carefully once the engine has cooled. Look for any visible leaks, but don’t risk burns. Bring it in so we can perform a pressure test and find the source fast.
5. Roaring or Humming at Higher Speeds
What it sounds like: A loud hum or roar that gets worse as you drive faster.
Possible issue: It could be a wheel bearing going bad, tire issues, or even problems with your transmission.
What to do: We’ll test drive and inspect the vehicle to determine if it’s a tire issue or something deeper. Wheel bearings are a safety concern, so don’t ignore this one.
6. Knocking in the Engine
What it sounds like: A rhythmic knock or pinging sound coming from the engine while driving.
Possible issue: This could be anything from low-quality fuel to engine timing problems, or even worn engine components.
7. Loud Exhaust or Rattling Under the Car
What it sounds like: A deep, rumbling exhaust note or rattling from beneath the vehicle.
Possible issue: You might have a loose heat shield, a damaged exhaust pipe, or a failing catalytic converter.
What to do: We’ll lift the vehicle and inspect the exhaust system. Some of these fixes are simple, but they all affect your emissions and fuel efficiency.
