Nissan Murano humming noise when accelerating can come from tires, wheel bearings, CV joints, brakes, or the transmission. The sound often changes with speed, road surface, or steering, which helps narrow the cause. This guide explains how to spot the problem early and what to do next.

Nissan Murano Humming Noise When Accelerating

If you hear a Nissan Murano humming noise when accelerating, do not ignore it. A soft hum may seem small at first, but it can point to a real issue under the car. The good news is that the sound often gives clues. It may come from the tires, the wheels, the CV axle, or even the transmission.

The Nissan Murano is a smooth SUV when it is in good shape. So when a humming sound starts during acceleration, it stands out fast. Some drivers hear it only at certain speeds. Others notice it more when turning, braking, or going uphill. That pattern matters. It helps you narrow down the cause before the problem gets worse.

In this guide, we will look at the most common reasons for a Nissan Murano humming noise when accelerating. We will also cover simple checks you can do at home, signs that point to a bigger repair, and ways to keep the issue from coming back.

What the Humming Noise Usually Means

Sound clues matter

A Nissan Murano humming noise when accelerating is often tied to parts that spin or move under load. That includes tires, hubs, bearings, axles, and gears. When one of these parts starts to wear out, it can make a low hum, drone, or growl.

The sound may change with speed. It may also change with engine load. That is why it helps to notice when the noise starts. Does it happen only when you press the gas? Does it stay the same when you let off the pedal? Does it get louder on one side of the road? These details matter.

Acceleration vs. road speed

One simple test is to listen for the difference between engine speed and road speed. If the hum gets louder as the car goes faster, even with light throttle, the issue may be in the wheels or drivetrain. If it only happens when you press the gas, the engine, transmission, or CVT may be involved.

This is why a Nissan Murano humming noise when accelerating should not be guessed at. The cause can be simple, but it can also be serious. A small noise today can become a costly repair later if it is ignored.

Common Causes of a Nissan Murano Humming Noise When Accelerating

1. Tire wear or bad tire patterns

Tires are one of the most common reasons for a Nissan Murano humming noise when accelerating. Uneven tread wear can make a steady hum that sounds like it is coming from the front or rear of the SUV. Cupping, feathering, or worn edges can all create this sound.

This is more likely if the tires are old, underinflated, or out of balance. It can also happen if alignment is off. If you hear the noise on smooth roads and rough roads alike, tires are a good place to start.

2. Wheel bearing wear

A bad wheel bearing is another top cause. Wheel bearings help the wheels spin smoothly. When they wear out, they often make a humming or growling noise that gets louder with speed. In many cases, the sound may change when you turn left or right.

For example, if the hum gets louder when you turn left, the right wheel bearing may be the problem. If it gets louder when you turn right, the left side may be bad. This is not a perfect rule, but it is a useful clue.

3. CV axle or CV joint problems

The Murano uses CV axles to send power to the wheels. If a CV joint wears out or loses grease, it can make a humming, clicking, or vibration sound. The noise may show up more during acceleration because the axle is under load.

You may also see grease near the wheel or a torn CV boot. If the boot is damaged, dirt and water can get in. That speeds up wear. A Nissan Murano humming noise when accelerating that also comes with vibration should make you check the CV axles soon.

4. Transmission or CVT issues

Many Murano models use a CVT, or continuously variable transmission. When a CVT starts to wear, it may make a whine, hum, or drone during acceleration. The sound can be light at first and then grow louder over time.

Transmission fluid problems can also add to the noise. Low fluid, old fluid, or internal wear can all cause strange sounds. If the hum changes with throttle input and feels like it comes from the center of the vehicle, the transmission should be checked.

If your Murano is due for service, a proper fluid check is smart. Regular care matters, just like it does in other Nissan models such as the 2017 Nissan Rogue oil change guide and the 2017 Nissan Pathfinder oil change guide. Healthy fluids help many parts last longer.

5. Brake drag or rotor issues

Sometimes the brakes are the hidden cause. A stuck caliper or dragging brake pad can create a humming or rubbing sound. It may be worse during acceleration because the car is working harder against the drag.

If one wheel feels hotter than the others after a drive, that is a warning sign. A bad rotor or worn pad can also make noise that sounds like a hum at speed. This is a safety issue, so do not wait too long if braking feels off.

How to Narrow Down the Source at Home

Listen during different driving conditions

Start by paying attention to when the Nissan Murano humming noise when accelerating happens. Does it appear only above 30 mph? Does it fade when you coast? Does it change on rough pavement? The more you notice, the easier it is to find the cause.

Try the same route at different speeds. If the hum stays tied to wheel speed, it is often tire or bearing related. If it changes mainly with throttle, the drivetrain or transmission may be the issue.

Check tire pressure and tread

Look at all four tires. Check for low pressure, uneven wear, bulges, or rough tread blocks. Run your hand across the tread. If it feels choppy or uneven, that can create noise.

Also check tire age. Old tires can harden and get noisy. If you are already thinking about replacements, a helpful place to start is our article on best tires for 2016 Nissan Murano. The right tire can improve both ride and sound.

Do a simple turning test

Find a safe, empty road and make gentle left and right turns. Listen closely. If the hum changes when you turn, a wheel bearing is a strong suspect. If the sound stays the same no matter what, tires or transmission may be more likely.

Do not make sharp moves. Keep it safe and simple. You only need small changes to hear the pattern.

Look for leaks or loose parts

Check under the car for fluid leaks. Look at the CV boots near the front wheels. If one is torn, that is a clear problem. Also look for loose splash shields, heat shields, or underbody covers. A loose panel can vibrate and sound like a hum.

Sometimes the fix is easy. A loose shield can be tightened in minutes. But if you see grease, fluid, or metal dust, the problem is more serious.

When the Noise Is Most Likely a Serious Problem

Loud noise that gets worse fast

A Nissan Murano humming noise when accelerating that grows louder over a short time is a red flag. That often means a bearing, axle, or transmission part is wearing quickly. If the sound changes from a hum to a growl or whine, get it checked soon.

Vibration with the noise

If the hum comes with shaking in the steering wheel, seat, or floor, the issue may be more than tires. A bent wheel, bad axle, or failing bearing can do this. Vibration means the problem is affecting how the car moves, not just how it sounds.

Warning lights or shifting issues

If the check engine light comes on, or if the Murano shifts oddly, the transmission may be involved. Slipping, delayed response, or high RPMs with little speed gain are all signs that need quick attention. A humming noise plus poor shifting should not be brushed off.

Repair Options and What to Expect

Tire service

If tires are the cause, the fix may be simple. Rotate them, balance them, or replace them if the wear is too far gone. Alignment may also be needed. This is often the cheapest path and can solve the Nissan Murano humming noise when accelerating very fast.

Wheel bearing replacement

Bad wheel bearings usually need replacement. This is not a part you want to keep driving on for long. The labor can vary based on which wheel is bad and how the hub is built. Once replaced, the humming often disappears right away.

CV axle or joint repair

If the CV axle is worn, the axle or joint may need replacement. If the boot is torn but the joint is still okay, catching it early can save money. Waiting too long can lead to full axle failure and more noise.

Transmission service

If the CVT is the source, a fluid service or deeper repair may be needed. Always use the correct fluid and follow the service schedule. The wrong fluid can make things worse. If the transmission is the issue, it is best to let a qualified shop inspect it.

How to Prevent the Noise From Coming Back

Keep up with tire care

Rotate tires on time. Keep them inflated to the right pressure. Get alignments when needed. These small steps help reduce uneven wear and road noise. Tire care is one of the easiest ways to avoid a Nissan Murano humming noise when accelerating later on.

Service the drivetrain on schedule

Do not skip fluid checks. Transmission fluid, differential fluid, and other service items help parts stay cool and smooth. Old fluid can make noise and wear worse. A little maintenance now can save a lot later.

Fix small issues early

If you hear a faint hum, do not wait until it becomes loud. Small noises often point to early wear. A simple repair now can prevent a bigger one later. That is true for bearings, axles, brakes, and tires.

Use good parts

Cheap parts may save money at first, but they can wear out fast and create noise again. Quality tires, hubs, and brake parts usually last longer and run smoother. If you are shopping for replacement parts, focus on fit, quality, and warranty.

Final Thoughts

A Nissan Murano humming noise when accelerating is common, but it should never be ignored. The cause may be as simple as worn tires, or it may be a sign of a failing wheel bearing, CV axle, brake issue, or transmission problem. The sound itself is your first clue. Use it.

Start with the easy checks. Look at the tires. Listen during turns. Watch for vibration. Check for leaks or worn boots. If the noise keeps getting worse, get a mechanic involved before the repair grows into something bigger. With the right fix, your Murano can go back to being quiet, smooth, and easy to drive.
