A new car is supposed to make you question your EMI, not your suspension.

Yet you drive your brand-new car over the first speed breaker and hear a “tak”, “clunk” or “khad-khad” from underneath. Suddenly, that shiny new car starts feeling like it has already completed 1 lakh km.

So, is suspension noise from a new car normal?

Sometimes, yes. A mild sound can come from normal suspension movement, tyres, loose items or the road surface. But a repeated car suspension noise, especially over bumps or while turning, should not be dismissed simply because the car is new.

A new car can also have a loose suspension component, incorrect torque, a manufacturing defect or an installation issue. New does not mean mechanically immortal.

In this guide, we explain the common causes of car suspension noise over bumps, car suspension noise when turning, car suspension noise at low speed and car suspension noise while driving, along with simple tests you can perform before visiting the service centre.

Is suspension noise in a new car normal?

A small amount of suspension noise can be normal, but a repeated or loud noise should be inspected.

The suspension system contains several moving parts, including:

• Shock absorbers

• Struts

• Springs

• Control arms

• Bushes

• Ball joints

• Stabiliser links

• Tie rods

• Wheel bearings

• Top mounts

• Steering components

These parts move whenever the car goes over a bump, turns, brakes or accelerates.

A soft thud over a large pothole can be normal, particularly on a stiffly tuned suspension.

A sharp clunk, repeated knocking, metallic rattle or grinding noise deserves more attention.

Quick rule

The exact cause cannot be confirmed from sound alone.

Why is my new car making suspension noise?

There are several possible reasons.

1. The suspension is naturally making noise

Suspension components move under load.

When the wheel moves upward over a bump, the spring compresses and the shock absorber moves through its travel.

Some cars produce a small amount of mechanical noise during this movement.

This is more noticeable in cars with:

• Stiff suspension

• Large wheels

• Low-profile tyres

• Heavy-duty suspension tuning

• High tyre pressures

If the sound is very mild and only happens on particularly rough roads, it may not indicate a defect.

2. A loose suspension component

This is one of the things that should be checked on a new car.

A suspension component may not be properly tightened during assembly or repair.

For example:

• Stabiliser link

• Control arm bolt

• Strut mounting bolt

• Shock absorber mounting

• Suspension bracket

A loose component can produce a clunking or knocking sound, particularly when the wheel moves quickly over a bump.

This is one reason you should not accept "new cars make some noise" as a complete diagnosis from a workshop.

Car suspension noise over bumps

This is one of the most common suspension complaints.

If your car makes a knocking, clunking or rattling noise over speed breakers and potholes, several components could be responsible.

Possible causes

A useful clue is whether the noise occurs over every bump or only on particularly sharp bumps.

If the noise happens repeatedly on ordinary speed breakers, have the car inspected.

Car suspension noise when turning

A car making noise while turning does not automatically mean the suspension is faulty.

The steering and suspension systems work together, so several components can create similar sounds.

Possible causes include:

• Strut top mount

• Ball joint

• Control arm bush

• Stabiliser components

• CV joint

• Steering linkage

• Wheel bearing

Clicking while making a tight turn

A repeated clicking sound while making a tight turn, particularly under acceleration, can point towards a CV joint issue.

Creaking while steering

A creaking or rubbing sound may come from a suspension mount, bush or spring-related component.

Grinding while turning

Grinding should not be ignored.

It could involve the wheel bearing, brake system or another rotating component.

Get it inspected instead of waiting for the noise to become louder.

Car suspension noise at low speed

Suspension noises can become easier to hear at low speed because there is less road and engine noise around you.

You may hear:

"tak... tak... tak"

while slowly crossing a speed breaker.

At low speed, listen for whether the sound occurs:

1. When the front wheels climb the bump

2. When the wheels come down

3. When only one wheel crosses the bump

4. While turning the steering

5. While braking

This information can help the mechanic identify the problem faster.

Car suspension noise while driving

If you hear suspension noise while driving on a normal road, first identify whether the sound changes with:

• Speed

• Steering angle

• Braking

• Acceleration

• Road surface

A noise that increases with vehicle speed may not actually be suspension-related.

It could come from:

• Tyres

• Wheel bearing

• Brakes

• Underbody panels

• Exhaust components

• Wheel arch liners

This distinction is important.

Otherwise, you could arrive at the workshop complaining about the suspension and leave with a new bill for a part that was never the problem.

Car suspension noise test: How to check it yourself

You can perform a basic test before visiting the service centre.

Do not crawl underneath the car or try to loosen suspension components yourself.

Test 1: Drive over a speed breaker

Drive slowly over a familiar speed breaker.

Keep the windows open.

Listen carefully.

Now repeat the test with the wheels straight.

Then repeat it while approaching at a slightly different angle, where safe.

If the noise consistently appears from one side, tell the technician.

Test 2: Try different road surfaces

Drive slowly over:

• Speed breakers

• Small potholes

• Uneven roads

• Smooth roads

If the noise only occurs on sharp bumps, tell the mechanic exactly that.

Test 3: Steering test

In a safe, open area, slowly turn the steering left and right.

Listen for:

• Clicking

• Creaking

• Grinding

• Knocking

Do not perform aggressive steering manoeuvres just to reproduce a noise.

Your suspension does not need an audition for a rally team.

Car suspension noise speed breaker test

A speed breaker can help reproduce a suspension noise because both front wheels move through suspension travel.

Try to identify when the noise happens.

Noise while going up

This can point towards components moving under compression.

Noise at the top

This may indicate a component reaching a particular position or suspension load.

Noise while coming down

This can point towards suspension rebound or movement in a mounting/component.

The test does not identify the exact faulty part, but it gives the technician useful information.

Car suspension noise diagnosis

A proper car suspension noise diagnosis should involve a physical inspection.

The technician may check:

• Suspension mounting bolts

• Shock absorbers

• Springs

• Control arm bushes

• Ball joints

• Stabiliser links

• Steering components

• Wheel bearings

• Tyres

• Brakes

• Underbody components

A road test is also important.

Suspension noises can be difficult to reproduce when the vehicle is stationary.

Can a new car have a faulty suspension component?

Yes.

A new car can have a defective component.

Possible reasons include:

• Manufacturing defect

• Assembly error

• Incorrect tightening

• Damaged component

• Transportation damage

• Incorrect wheel alignment

• Foreign object or loose underbody component

The probability may be lower than in an older car, but it is not zero.

That is why warranty exists.

Should you take a new car back to the dealer for suspension noise?

Yes, if the noise is repeated, loud or unusual.

If the car is under warranty, report the issue to the authorised service centre.

Do not wait for months hoping the sound will disappear.

When visiting the workshop, avoid saying only:

Give them useful information.

For example:

That is much easier to diagnose.

Record the suspension noise

If the noise happens randomly, record it on your phone.

Try to capture:

• The road

• Vehicle speed

• Steering position

• The sound

• Whether the noise occurs while entering or leaving the bump

A video can save you from the classic service-centre experience:

Customer: "Sir, awaaz aa rahi hai."

Technician: "Abhi toh nahi aa rahi."

Customer: "But it comes while driving."

Technician: "Drive karte rahiye."

And suddenly the noise develops stage fright.

When is suspension noise dangerous?

Get the vehicle checked promptly if suspension noise is accompanied by:

• Steering vibration

• Vehicle pulling to one side

• Excessive bouncing

• Uneven tyre wear

• Steering becoming heavy

• Grinding noise

• Visible fluid leakage from a shock absorber

• Loose steering

• Severe knocking

• Changes in braking behaviour

• Wheel wobble

If the steering or wheel feels unstable, avoid driving the vehicle unnecessarily.

How to fix car suspension noise

The repair depends completely on the source.

Do not replace the entire suspension simply because the car makes a noise.

Diagnose first, replace second.

Does suspension noise mean the car is defective?

Not necessarily.

A noise does not automatically mean the car has a major manufacturing defect.

The important factors are:

• Type of noise

• Frequency

• Location

• Driving condition

• Whether the noise is getting worse

• Whether there are other symptoms

A mild suspension thud over a large pothole can be normal.

A repeated metallic clunk over every speed breaker in a brand-new car deserves an inspection.

New car suspension noise: What should you do?

If your new car develops a suspension noise, follow these steps:

1. Identify the condition

Note whether it happens over bumps, while turning, braking or driving straight.

2. Record the sound

Use your phone if possible.

3. Check simple things

Make sure there are no loose tools, spare-wheel components or objects in the boot creating the noise.

4. Visit the authorised service centre

Especially if the car is under warranty.

5. Ask for a road test

The technician should try to reproduce the noise.

6. Ask for the diagnosis in writing

This creates a useful service record if the problem continues.
