When does my Kia E Niro produce a loud noise?
One way to detect a noise from your Kia E Niro is to establish when it appears. Indeed, some complications can be related to parts that are only stressed under certain types of conditions. It is this method that we will focus on in this first part.
Loud noise Kia E Niro when accelerating
Loud noise on Kia E Niro that happens when you are accelerating can be symptomatic of different failures. Indeed, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will induce a much higher noise than during normal operation. Additionally, it is also highly plausible that loud noise on your Kia E Niro is in connection with 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 issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Kia E Niro is stopped
If your Kia E Niro makes a loud noise while not accelerating, engine on, the issue 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 reason.

The loud noise comes from the wheels of my Kia E Niro
As we have seen previously, loud noise from the wheels of your Kia E Niro may be in connection with 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 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, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Kia E Niro that is the issue, you will tend to feel a vibration in the direction of the automobile as you go faster. In both cases, you will have to go to your auto mechanic to replace the tires or accomplish a balancing.

The loud noise comes from the engine of my Kia E Niro
In case you have discovered loud noise as coming from the engine of your Kia E Niro, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be linked 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 Kia E Niro is related to air intake, the control 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 trouble, take your automobile to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Kia E Niro, 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 Kia E Niro, 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 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.
