When does my Toyota C-hr produce a loud noise?
One way to find a noise from your Toyota C-hr is to define when it appears. Indeed, some complications can be related 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 Toyota C-hr when accelerating
Loud noise on Toyota C-hr that shows up when you are accelerating can be symptomatic of several failures. In fact, 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 process. In addition, it is also highly plausible that loud noise on your Toyota C-hr is linked to a wheel bearing, which is one of the most common causes 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 trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Toyota C-hr is stopped
If your Toyota C-hr makes a loud noise while not accelerating, engine on, the trouble may be related to poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.

Now that we have determined the origin of the sound, we will deal with the verification step to make sure that this is the concern you are enduring.

The loud noise comes from the wheels of my Toyota C-hr
As we have seen earlier in this article, loud noise from the wheels of your Toyota C-hr may be related to two main complications. 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 straight 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 Toyota C-hr that is the issue, 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 technician to change the tires or execute a balancing.

The loud noise comes from the engine of my Toyota C-hr
In case you have discovered loud noise as coming from the engine of your Toyota C-hr, 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 experience a power loss during your acceleration. If the loud noise on your Toyota C-hr 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 cause 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 car to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have discovered comes from the exhaust pipe of your Toyota C-hr, 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 Toyota C-hr, 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 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.
