Why Is My Car Making a Squealing Noise When I Drive?
That high-pitched squeal coming from your car can stop you in your tracks—literally and emotionally. Whether it happens when you start driving, hit the brakes, or just roll through a parking lot, it's not a sound you want to ignore.
At Wayside Garage, we help drivers every day who ask the same question:
“What’s that squealing noise, and do I need to worry?”
Let’s break down what could be causing it—and what you should do next.
🔍 What Causes a Squealing Noise While Driving?
There are a few key areas to check when you hear that sharp, squeaky sound:
1. Worn Brake Pads
🛑 This is by far the most common cause.
Brake pads are designed with a wear indicator—a small metal tab that squeals when the pads get too thin. It’s your car’s way of telling you it’s time for new brakes.
Signs it’s your brakes:
The squealing happens when you press the brake pedal
It’s coming from the front wheels
You haven’t had a brake inspection in a while
2. Glazed or Overheated Brake Rotors
If your brakes have been overused or overheated, the rotors can become shiny or "glazed," causing them to squeal—even if your brake pads still have life left.
3. Loose or Worn Serpentine Belt
If the squealing happens more when you start the car or accelerate, it might be the serpentine belt. This belt drives key components like the alternator and power steering. If it’s loose, worn, or cracked, it can squeal under pressure.
4. Dust or Debris in the Brakes
Small rocks or debris can get lodged in the brake components and cause a squeal—even if nothing is technically worn out. A simple cleaning and inspection can clear it up.
5. Wheel Bearing or Suspension Noise
While rare, a squeal near the tire area could come from a dry or damaged wheel bearing, especially if it’s paired with a humming or grinding sound.
🤔 Is It Safe to Drive with a Squealing Noise?
Short answer: Maybe—but you shouldn’t wait to find out.
Some causes are minor, but others (like worn brake pads or failing belts) can quickly lead to bigger, more expensive problems—or safety risks.
