It is never relaxing to perceive a sound in your automobile that you don’t know the cause of. So, what if you find a loud noise that continues on your Nissan Leaf? It is very plausible that this is a minor trouble, but before beeing sure, it is better to do some verifications. Whether that loud noise comes from the front of the vehicle, from the rear, whether it shows up when you accelerate or when you are parked, our team has made this content to help you solve it. First, we will point out the possible reasons for the problem according to when loud noise shows up on your Nissan Leaf, and then we will give attention to 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 Nissan Leaf generate a loud noise?
One way to find a noise from your Nissan Leaf is to define when it occurs. Indeed, some trouble can be connected to parts that are only stressed under certain occasions. It is this technique that we will focus on in this first part.
Loud noise Nissan Leaf when accelerating
Loud noise on Nissan Leaf that appears 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 cause a much higher noise than during normal operation. Furthermore, it is also highly plausible that loud noise on your Nissan Leaf is linked to a wheel bearing, which is one of the most common causes of these types of symptoms. Another alternative 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 gains speed.
When my Nissan Leaf is stopped
If your Nissan Leaf makes a loud noise while not accelerating, engine on, the trouble may be connected 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 Nissan Leaf and how can I be sure of its origin?
Now that we have located the cause of the sound, we will focus on the verification stage to be certain that this is the concern you are encountering.
The loud noise comes from the wheels of my Nissan Leaf
As we have seen before, loud noise from the wheels of your Nissan Leaf may be connected to two main problems. 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 consider 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 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 Leaf that is the trouble, 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 Nissan Leaf
In case you have recognized loud noise as coming from the engine of your Nissan Leaf, 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 experience a power loss during your acceleration. If the loud noise on your Nissan Leaf 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 examine that the engine idle speed is not random. In case you confirm one of these two disorders, take your car to your service garage .
Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Nissan Leaf, 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 Nissan Leaf, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To verify 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.
