When does my Hyundai Sonata generate a loud noise?
One way to discern a noise from your Hyundai Sonata is to identify when it shows up. Indeed, some complications can be related to components that are only stressed under certain occasions. It is this process that we will focus on in this first part.
Loud noise Hyundai Sonata when accelerating
Loud noise on Hyundai Sonata that occurs when you are accelerating can be symptomatic of several failures. Indeed, if you feel 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 use. In addition, it is also highly possible that loud noise on your Hyundai Sonata is linked to a wheel bearing, which is one of the most common origins 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 possible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

The loud noise comes from the wheels of my Hyundai Sonata
As we have seen earlier in this article, loud noise from the wheels of your Hyundai Sonata 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 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 Hyundai Sonata that is the trouble, you will tend to feel a vibration in the direction of the car as you go faster. In both cases, you will have to go to your mechanic to replace the tires or accomplish a balancing.

The loud noise comes from the engine of my Hyundai Sonata
In case you have identified loud noise as coming from the engine of your Hyundai Sonata, 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 experience a power loss during your acceleration. If the loud noise on your Hyundai Sonata 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 cause 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 trouble, take your car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Hyundai Sonata, it is highly possible 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 Hyundai Sonata, 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 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.
