It is never relaxing to notice a sound in your car that you don’t know the starting point of. So, what if you recognize a loud noise that continues on your Nissan NV? It is highly plausible that this is a minor issue, but before beeing sure, it is better to do some investigations. Whether that loud noise comes from the front of the vehicle, from the rear, whether it happens when you accelerate or when you are parked, our team has written this content to help you solve it. First, we will detail the possible causes for the trouble according to when loud noise shows up on your Nissan NV, and then we will focus on the region of origin of the noise. In any case, if this noise continues, follow these suggestions to help you find the source.

When does my Nissan NV make a loud noise?
One way to discern a noise from your Nissan NV is to establish when it occurs. Indeed, some trouble can be linked to components that are only stressed under certain circumstances. It is this approach that we will focus on in this first part.
Loud noise Nissan NV when accelerating
Loud noise on Nissan NV that takes place when you are accelerating can be symptomatic of several failures. In fact, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will cause a much higher noise than during normal process. In addition, it is also highly plausible that loud noise on your Nissan NV is connected to a wheel bearing, which is one of the most common origins of these types of manifestations. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Nissan NV is stopped
If your Nissan NV makes a loud noise while not accelerating, engine on, the issue may be linked to poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.
Where does loud noise come from on my Nissan NV and how can I be sure of its origin?
Now that we have defined the cause of the sound, we will concentrate on the verification stage to make sure that this is the concern you are experiencing.

The loud noise comes from the wheels of my Nissan NV
As we have seen before, loud noise from the wheels of your Nissan NV may be linked to two main complications. If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So bear in mind to verify by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case swap it or them right away. If it is a deformed tire, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Nissan NV that is the matter, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your technician to change the tires or accomplish a balancing.

The loud noise comes from the engine of my Nissan NV
In case you have discovered loud noise as coming from the engine of your Nissan NV, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected to a compression loss during the engine ramp-up phase, so you should encounter a power loss during your acceleration. If the loud noise on your Nissan NV is related to air intake, the control will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would generate an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then verify that the engine idle speed is not random. In case you confirm one of these two problems, take your car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Nissan NV, it is highly plausible that you have rust if your vehicle is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Nissan NV, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To verify this, get help from someone who will stand under the vehicle while you accelerate to find the exact area of starting point of this noise. If it is a hole, you can repair it with a putty provided for this purpose, or, if it is a collar, “reattach” it. If it is cut or the hole is too big, it is better to get closer to your mechanic.
