One way to detect a noise from your Nissan Qashqai is to establish when it occurs. Indeed, some complications can be connected to components that are only stressed under certain conditions. It is this process that we will focus on in this first part.
Loud noise Nissan Qashqai when accelerating
Loud noise on Nissan Qashqai that shows up when you are accelerating can be symptomatic of several failures. Indeed, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will cause a much higher noise than during normal operation. Moreover, it is also highly plausible that loud noise on your Nissan Qashqai is related to a wheel bearing, which is one of the most common causes of these types of signs of illness. 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 increases speed.

When my Nissan Qashqai is stopped

The loud noise comes from the wheels of my Nissan Qashqai
As we have seen earlier in this article, loud noise from the wheels of your Nissan Qashqai may be in connection with 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 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 replace it or them right away. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Nissan Qashqai 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 mechanic to replace the tires or do a balancing.

The loud noise comes from the engine of my Nissan Qashqai
In case you have identified loud noise as coming from the engine of your Nissan Qashqai, 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 Nissan Qashqai 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 automobile to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have discovered comes from the exhaust pipe of your Nissan Qashqai, 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 Nissan Qashqai, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate this, get help from someone who will stand under the automobile while you accelerate to find the exact area of source 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.
