When does my Lexus IS make a loud noise?
One way to discover a noise from your Lexus IS is to define when it occurs. Indeed, some trouble can be connected 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 IS when accelerating
Loud noise on Lexus IS that takes place when you are accelerating can be symptomatic of several 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 create a much higher noise than during normal use. Moreover, it is also highly plausible that loud noise on your Lexus IS is related to a wheel bearing, which is one of the most common origins of these types of symptoms. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Lexus IS is stopped

The loud noise comes from the wheels of my Lexus IS
As we have seen previously, loud noise from the wheels of your Lexus IS may be connected to two main trouble. 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 swap it or them as soon as possible. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Lexus IS that is the matter, you will tend to feel a vibration in the direction of the automobile as you go faster. In both cases, you will have to go to your mechanic to swap the tires or execute a balancing.

The loud noise comes from the engine of my Lexus IS
In case you have identified loud noise as coming from the engine of your Lexus IS, 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 encounter a power loss during your acceleration. If the loud noise on your Lexus IS 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 induce 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 automobile to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Lexus IS, it is highly plausible that you have rust if your automobile is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Lexus IS, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To confirm this, get help from someone who will stand under the automobile 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.
