It is never relaxing to perceive a sound in your automobile that you don’t know the starting point of. So, what if you find a loud noise that continues on your Mazda CX 5? It is extremely plausible that this is a minor problem, but before beeing sure, it is better to accomplish some investigations. Whether that loud noise comes from the front of the car, 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 detail the possible reasons for the problem according to when loud noise appears on your Mazda CX 5, and then we will concentrate on the region of origin of the noise. In any case, if this noise remains, follow these instructions to help you find the origin.

When does my Mazda CX 5 produce a loud noise?
One way to identify a noise from your Mazda CX 5 is to determine when it appears. Indeed, some trouble can be related to components that are only stressed under certain conditions. It is this technique that we will focus on in this first part.
Loud noise Mazda CX 5 when accelerating
Loud noise on Mazda CX 5 that shows up when you are accelerating can be symptomatic of several failures. Indeed, if you experience 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 plausible that loud noise on your Mazda CX 5 is linked to a wheel bearing, which is one of the most common causes 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 CX 5 is stopped
If your Mazda CX 5 makes a loud noise while not accelerating, engine on, the problem may be in connection with poor air intake. An air intake hose that has come loose or has a hole in it may be the cause.
Where does loud noise come from on my Mazda CX 5 and how can I be sure of its origin?
Now that we have identified the source of the noise, we will focus on the verification step to ensure that this is the concern you are having.

The loud noise comes from the wheels of my Mazda CX 5
As we have seen previously, loud noise from the wheels of your Mazda CX 5 may be in connection with 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 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 swap it or them quickly. 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 CX 5 that is the trouble, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your auto mechanic to swap the tires or execute a balancing.

The loud noise comes from the engine of my Mazda CX 5
In case you have discovered loud noise as coming from the engine of your Mazda CX 5, 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 Mazda CX 5 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 check that the engine idle speed is not random. In case you confirm one of these two disorders, take your vehicle to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have noticed comes from the exhaust pipe of your Mazda CX 5, 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 Mazda CX 5, 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 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.
