When does my Acura RDX generate a loud noise?
One way to find a noise from your Acura RDX is to identify when it shows up. Indeed, some complications can be related to components that are only stressed under certain types of conditions. It is this technique that we will focus on in this first part.
Loud noise Acura RDX when accelerating
Loud noise on Acura RDX that occurs when you are accelerating can be symptomatic of several failures. Indeed, 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 operation. Additionally, it is also highly plausible that loud noise on your Acura RDX is related to a wheel bearing, which is one of the most common origins 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 issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Acura RDX is stopped
If your Acura RDX makes a loud noise while not accelerating, engine on, the issue may be related to poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.

Now that we have located the origin of the sound, we will deal with the verification stage to be sure that this is the issues you are going through.

The loud noise comes from the wheels of my Acura RDX
As we have seen previously, loud noise from the wheels of your Acura RDX may be related 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 remember 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 straight 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 Acura RDX that is the trouble, 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 swap the tires or execute a balancing.

The loud noise comes from the engine of my Acura RDX
In case you have discovered loud noise as coming from the engine of your Acura RDX, 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 experience a power loss during your acceleration. If the loud noise on your Acura RDX 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 induce 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 problems, take your vehicle to your mechanic .

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