It is never enjoyable to find out a sound in your vehicle that you don’t know the origin of. So, what if you detect a loud noise that persists on your Lincoln MKZ? It is extremely plausible that this is a minor issue, but before beeing sure, it is better to do some investigations. Whether that loud noise comes from the front of the automobile, from the rear, whether it happens when you accelerate or when you are parked, our team has written this article to help you solve it. First, we will summarize the possible reasons for the issue according to when loud noise appears on your Lincoln MKZ, and then we will look into the region of origin of the noise. In any case, if this noise remains, follow these instructions to help you find the source.

When does my Lincoln MKZ produce a loud noise?
One way to find a noise from your Lincoln MKZ is to establish when it occurs. Indeed, some complications can be connected to parts that are only stressed under certain types of conditions. It is this approach that we will focus on in this first part.
Loud noise Lincoln MKZ when accelerating
Loud noise on Lincoln MKZ that happens when you are accelerating can be symptomatic of multiple failures. Indeed, if you feel 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 use. Additionally, it is also highly plausible that loud noise on your Lincoln MKZ is linked to a wheel bearing, which is one of the most common causes of these types of signs of illness. 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 gains speed.

When my Lincoln MKZ is stopped
If your Lincoln MKZ makes a loud noise while not accelerating, engine on, the issue may be linked to poor air intake. An air intake hose that has come loose or has a hole in it may be the cause.
Where does loud noise come from on my Lincoln MKZ and how can I be sure of its origin?
Now that we have defined the origin of the sound, we will look into the verification stage to make sure that this is the concern you are having.

The loud noise comes from the wheels of my Lincoln MKZ
As we have seen earlier in this article, loud noise from the wheels of your Lincoln MKZ may be linked 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 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 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 Lincoln MKZ that is the issue, 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 mechanic to replace the tires or do a balancing.

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

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have discovered comes from the exhaust pipe of your Lincoln MKZ, it is highly plausible that you have rust if your automobile is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Lincoln MKZ, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure this, get help from someone who will stand under the automobile while you accelerate to find the exact area of source 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.
