When and where these noises occur, such as during braking, turning, or going over bumps, can reveal a lot about what’s wrong.

Keep reading as we break down the most common reasons your car makes a squeaking noise when driving and how to fix it before a small squeak turns into a costly car repair.

Why Does Your Car Squeak When Driving? (5 Common Scenarios)

Here are five situations where a squeaky noise may occur and the common cause behind each:

1. Squeaking at Low Speed

Squeaks at low speeds usually result from the following problems:

2. Squeaking When Turning

If you hear a squeak while turning the steering wheel, the problem can come from:

3. Squeaking When Braking

If your car only squeaks when you apply the brakes, the issue almost certainly lies in the braking system. Here’s what could be causing it:

4. Squeaking During Acceleration or Deceleration

Squeaks while accelerating or decelerating are often caused by the following issues:

5. Squeaking When Going Over Bumps

If your car squeaks while driving over bumps or uneven roads, it’s likely due to suspension problems like:  

NOTE: Serpentine belt issues can cause a small squeak or high-pitched squeal when you start the engine. Since the belt powers the alternator, A/C, power steering, and cooling fan, any wear or misalignment may put it under stress at ignition, leading to a squealing noise at startup.

Now that you know what’s causing the squeak, let’s explore whether it’s safe to continue driving.

Is it Safe to Drive a Squeaky Car?

No, it’s not recommended to drive a car that’s making a squeaky noise, especially if you don’t know what’s causing it.

Continuing to drive with a squeak can strain components that may already be worn or failing. This can lead to reduced control, poor handling, and unpredictable vehicle behavior, particularly while braking or turning.

In severe cases, it could result in a complete brake, power steering, or suspension failure, leaving you stranded or even causing an accident. 

That’s why it’s essential to identify the root cause ASAP.

What Should You Do If Your Car Is Squeaking?

With many possible causes, a squeaking noise when driving can be tricky to trace and even harder to fix without the proper tools or expertise. 

If you’re unsure where the noise is coming from, book a professional inspection. A mobile auto repair mechanic can assess your car on-site and pinpoint the issue.

Here’s what they’ll typically do:

  1. Identify when the squeak occurs — at low speed or during braking, turning, accelerating, and going over bumps.
  2. Based on the source, inspect the braking system for worn pads, rusty rotors, or a stuck brake caliper.
  3. Check suspension components like bushings, ball joints, sway bar links, and struts for wear or damage.
  4. Examine the serpentine and timing belts for cracks, fraying, or tension issues.
  5. Inspect the alternator and water pump pulleys for looseness or worn bearings.
  6. Check the power steering pump, fluid, and system for leaks.
  7. Lubricate joints if dryness or friction is causing the squeak.
  8. Test drive your car to ensure there are no odd squeaks under any driving conditions.

Now, let’s go over how much these fixes might cost you.

How Much Does it Cost to Fix Car Squeaking Noises?

The car repair costs to fix squeaky noises can range widely from $20 to $5,000. Before starting any work, your mechanic will inspect the vehicle to identify the source of the squeak. This diagnostic check will typically cost between $20 and $500.

Based on what the mechanic finds, here’s a general breakdown of estimated costs for common repairs and replacements (labor included):

TIP: To help manage these costs, consider mechanical breakdown insurance. It typically covers replacement parts, labor, and even car hire during repairs. Some manufacturers also offer extended warranties (up to seven years) when you buy a new car

5 Useful Tips to Prevent Car Squeaks While Driving

Follow these best practices to help your car run quietly:

  1. Check and maintain engine oil, brake fluid, and power steering fluid levels to avoid unnecessary friction between moving parts.
  1. If debris enters any fluid reservoir, drain and clean it thoroughly before refilling to prevent damage and squeaking.
  1. Keep moving parts such as suspension bushings, joints, and hinges properly lubricated to prevent squeaks caused by dryness or friction.
  1. Depending on your vehicle make and driving habits, replace the: 
    • Brake pads every 20,000 to 75,000 miles 
    • Serpentine belt every 50,000 to 100,000 miles
    • Timing belt every 60,000 to 100,000 miles
