When does my Lexus UX generate a loud noise?
One way to identify a noise from your Lexus UX is to establish when it appears. Indeed, some complications can be related to parts that are only stressed under certain occasions. It is this approach that we will focus on in this first part.
Loud noise Lexus UX when accelerating
Loud noise on Lexus UX that takes place when you are accelerating can be symptomatic of different failures. In fact, if you feel 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. In addition, it is also highly possible that loud noise on your Lexus UX is related to a wheel bearing, which is one of the most common causes of these types of symptoms. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

The loud noise comes from the wheels of my Lexus UX
As we have seen before, loud noise from the wheels of your Lexus UX may be related to two main problems. 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 check 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, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Lexus UX 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 auto mechanic to replace the tires or accomplish a balancing.

The loud noise comes from the engine of my Lexus UX
In case you have recognized loud noise as coming from the engine of your Lexus UX, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated with a compression loss during the engine ramp-up phase, so you should experience a power loss during your acceleration. If the loud noise on your Lexus UX 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 check that the engine idle speed is not random. In case you confirm one of these two trouble, take your car to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Lexus UX, 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 Lexus UX, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure 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.
