When does my Nissan Pathfinder generate a loud noise?
One way to discover a noise from your Nissan Pathfinder is to determine when it occurs. Indeed, some concerns can be connected to components that are only stressed under certain types of conditions. It is this approach that we will focus on in this first part.
Loud noise Nissan Pathfinder when accelerating
Loud noise on Nissan Pathfinder that starts when you are accelerating can be symptomatic of different failures. Indeed, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will provoke a much higher noise than during normal operation. Furthermore, it is also highly possible that loud noise on your Nissan Pathfinder is associated with a wheel bearing, which is one of the most common origins of these types of signs of illness. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

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

The loud noise comes from the wheels of my Nissan Pathfinder
As we have seen before, loud noise from the wheels of your Nissan Pathfinder may be linked to two main disorders. 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 remember to examine 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 replace it or them right away. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Nissan Pathfinder that is the issue, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both cases, you will have to go to your auto technician to change the tires or execute a balancing.

The loud noise comes from the engine of my Nissan Pathfinder
In case you have identified loud noise as coming from the engine of your Nissan Pathfinder, 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 Pathfinder is related to air intake, the check 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 examine that the engine idle speed is not random. In case you confirm one of these two trouble, take your vehicle 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 Pathfinder, it is highly possible 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 Pathfinder, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate this, get help from someone who will stand under the vehicle while you accelerate to find the exact area of source 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.
