When does my Buick Regal generate a loud noise?
One way to detect a noise from your Buick Regal is to establish when it shows up. Indeed, some concerns can be linked to parts that are only stressed under certain circumstances. It is this method that we will focus on in this first part.
Loud noise Buick Regal when accelerating
Loud noise on Buick Regal 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 generate a much higher noise than during normal process. Moreover, it is also highly plausible that loud noise on your Buick Regal is linked to a wheel bearing, which is one of the most common origins of these types of manifestations. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Buick Regal is stopped

The loud noise comes from the wheels of my Buick Regal
As we have seen earlier in this article, loud noise from the wheels of your Buick Regal may be in connection with 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 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 straight away. If it is a deformed tire, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Buick Regal that is the trouble, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your auto technician to swap the tires or do a balancing.

The loud noise comes from the engine of my Buick Regal
In case you have recognized loud noise as coming from the engine of your Buick Regal, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected with 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 Buick Regal 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 check that the engine idle speed is not random. In case you confirm one of these two disorders, take your car 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 Buick Regal, 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 Buick Regal, 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 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.
