First, we will summarize the possible reasons for the problem according to when loud noise shows up on your Mazda Mx5, and then we will look into the region of origin of the noise. In any case, if this noise lasts, follow these advice to help you find the origin.

When does my Mazda Mx5 produce a loud noise?
One way to detect a noise from your Mazda Mx5 is to define when it occurs. Indeed, some trouble can be linked 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 Mazda Mx5 when accelerating
Loud noise on Mazda Mx5 that takes place 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 use. Moreover, it is also highly plausible that loud noise on your Mazda Mx5 is linked to a wheel bearing, which is one of the most common origins of these types of signs of illness. 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 Mazda Mx5 is stopped
If your Mazda Mx5 makes a loud noise while not accelerating, engine on, the problem 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.
Where does loud noise come from on my Mazda Mx5 and how can I be sure of its origin?
Now that we have identified the cause of the noise, we will focus on the verification step to ensure that this is the concern you are encountering.

The loud noise comes from the wheels of my Mazda Mx5
As we have seen previously, loud noise from the wheels of your Mazda Mx5 may be related 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 change 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 Mazda Mx5 that is the matter, you will tend to feel a vibration in the direction of the automobile as you go faster. In both situations, you will have to go to your auto technician to change the tires or perform a balancing.

The loud noise comes from the engine of my Mazda Mx5
In case you have recognized loud noise as coming from the engine of your Mazda Mx5, 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 encounter a power loss during your acceleration. If the loud noise on your Mazda Mx5 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 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 garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Mazda Mx5, 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 Mazda Mx5, 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 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.
