It is never relaxing to find out a sound in your vehicle that you don’t know the cause of. So, what if you identify a loud noise that persists on your Lexus CT? It is very plausible that this is a minor problem, but before beeing sure, it is better to complete some inspections. 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 made this article to help you solve it. First, we will describe the possible causes for the issue according to when loud noise shows up on your Lexus CT, and then we will focus on the region of origin of the noise. In any case, if this noise lasts, follow these advice to help you find the source.

When does my Lexus CT produce a loud noise?
One way to detect a noise from your Lexus CT is to determine when it shows up. Indeed, some complications can be linked to components that are only stressed under certain occasions. It is this process that we will focus on in this first part.
Loud noise Lexus CT when accelerating
Loud noise on Lexus CT that takes place 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 generate a much higher noise than during normal use. Moreover, it is also highly plausible that loud noise on your Lexus CT is connected to a wheel bearing, which is one of the most common origins 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 problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Lexus CT is stopped
If your Lexus CT makes a loud noise while not accelerating, engine on, the problem may be connected to poor air intake. An air intake hose that has come loose or has a hole in it may be the induce.
Where does loud noise come from on my Lexus CT and how can I be sure of its origin?
Now that we have found the source of the noise, we will look into the verification stage to make sure that this is the matter you are encountering.

The loud noise comes from the wheels of my Lexus CT
As we have seen previously, loud noise from the wheels of your Lexus CT may be connected 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 keep 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 Lexus CT that is the issue, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both circumstances, 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 CT
In case you have recognized loud noise as coming from the engine of your Lexus CT, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected 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 CT 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 cause 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 trouble, take your vehicle to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Lexus CT, 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 Lexus CT, 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 vehicle 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.
