When does my Lexus NX produce a loud noise?
One way to find a noise from your Lexus NX is to identify when it appears. Indeed, some trouble can be related to components that are only stressed under certain occasions. It is this approach that we will focus on in this first part.
Loud noise Lexus NX when accelerating
Loud noise on Lexus NX that shows up when you are accelerating can be symptomatic of multiple 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 create a much higher noise than during normal operation. Moreover, it is also highly plausible that loud noise on your Lexus NX is connected to a wheel bearing, which is one of the most common causes of these types of manifestations. Another alternative 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 gains speed.

When my Lexus NX is stopped
If your Lexus NX makes a loud noise while not accelerating, engine on, the issue may be in connection with 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 Lexus NX and how can I be sure of its origin?
Now that we have located the origin of the noise, we will concentrate on the verification stage to make certain that this is the concern you are encountering.

The loud noise comes from the wheels of my Lexus NX
As we have seen previously, loud noise from the wheels of your Lexus NX may be in connection with 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 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 change it or them quickly. 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 Lexus NX that is the matter, you will tend to feel a vibration in the direction of the automobile as you go faster. In both circumstances, you will have to go to your auto mechanic to replace the tires or accomplish a balancing.

The loud noise comes from the engine of my Lexus NX
In case you have identified loud noise as coming from the engine of your Lexus NX, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be linked 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 Lexus NX 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 disorders, take your automobile 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 Lexus NX, it is highly plausible that you have rust if your car is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Lexus NX, 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 car while you accelerate to find the exact area of origin 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.
