It is never relaxing to experience a sound in your vehicle that you don’t know the starting point of. So, what if you detect a loud noise that continues on your Mitsubishi Lancer? It is highly plausible that this is a minor problem, but before beeing sure, it is better to accomplish 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 made this article to help you solve it. First, we will describe the possible reasons for the problem according to when loud noise appears on your Mitsubishi Lancer, and then we will give attention to the region of origin of the noise. In any case, if this noise lasts, follow these recommendations to help you find the source.

When does my Mitsubishi Lancer produce a loud noise?
One way to discern a noise from your Mitsubishi Lancer is to identify when it appears. Indeed, some problems can be connected to parts that are only stressed under certain types of conditions. It is this process that we will focus on in this first part.
Loud noise Mitsubishi Lancer when accelerating
Loud noise on Mitsubishi Lancer that occurs 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 induce a much higher noise than during normal use. Furthermore, it is also highly plausible that loud noise on your Mitsubishi Lancer is related to a wheel bearing, which is one of the most common origins 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 problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Mitsubishi Lancer is stopped
If your Mitsubishi Lancer 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 Mitsubishi Lancer and how can I be sure of its origin?
Now that we have located the origin of the sound, we will concentrate on the verification step to ensure that this is the concern you are encountering.

The loud noise comes from the wheels of my Mitsubishi Lancer
As we have seen previously, loud noise from the wheels of your Mitsubishi Lancer may be connected to two main complications. 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 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 Mitsubishi Lancer that is the problem, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your auto mechanic to replace the tires or perform a balancing.

The loud noise comes from the engine of my Mitsubishi Lancer
In case you have discovered loud noise as coming from the engine of your Mitsubishi Lancer, 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 Mitsubishi Lancer 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 induce 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 vehicle to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Mitsubishi Lancer, 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 Mitsubishi Lancer, 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 vehicle 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.
