It is never pleasant to perceive a noise in your vehicle that you don’t know the starting point of. So, what if you detect a loud noise that continues on your Honda Accord? It is extremely plausible that this is a minor problem, but before beeing sure, it is better to operate some checks. 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 written this content to help you fix it. First, we will detail the possible explanations for the problem according to when loud noise shows up on your Honda Accord, and then we will focus on the region of origin of the noise. In any case, if this noise continues, follow these suggestions to help you find the source.
When does my Honda Accord make a loud noise?
One way to identify a noise from your Honda Accord is to determine when it shows up. Indeed, some problems 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 Honda Accord when accelerating
Loud noise on Honda Accord that occurs 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 create a much higher noise than during normal operation. In addition, it is also highly plausible that loud noise on your Honda Accord is connected to a wheel bearing, which is one of the most common causes of these types of manifestations. 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 Honda Accord is stopped
If your Honda Accord makes a loud noise while not accelerating, engine on, the problem 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 Honda Accord and how can I be sure of its origin?
Now that we have uncovered the origin of the sound, we will deal with the verification step to make sure that this is the issues you are having.
The loud noise comes from the wheels of my Honda Accord
As we have seen previously, loud noise from the wheels of your Honda Accord may be connected to 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 bear 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 change it or them quickly. 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 Honda Accord that is the problem, 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 change the tires or perform a balancing.
The loud noise comes from the engine of my Honda Accord
In case you have recognized loud noise as coming from the engine of your Honda Accord, 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 Honda Accord 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 discovered comes from the exhaust pipe of your Honda Accord, 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 Honda Accord, 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.
