When does my Subaru Crosstrek produce a loud noise?

Loud noise Subaru Crosstrek when accelerating
Loud noise on Subaru Crosstrek that takes place when you are accelerating can be symptomatic of several failures. Indeed, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will cause a much higher noise than during normal operation. In addition, it is also highly possible that loud noise on your Subaru Crosstrek 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 possible that the trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

The loud noise comes from the wheels of my Subaru Crosstrek
As we have seen before, loud noise from the wheels of your Subaru Crosstrek may be connected to two main problems. 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 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 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 Subaru Crosstrek that is the issue, you will tend to feel a vibration in the direction of the automobile as you go faster. In both situations, you will have to go to your technician to swap the tires or do a balancing.

The loud noise comes from the engine of my Subaru Crosstrek
In case you have recognized loud noise as coming from the engine of your Subaru Crosstrek, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated 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 Subaru Crosstrek 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 verify that the engine idle speed is not random. In case you confirm one of these two trouble, take your automobile 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 Subaru Crosstrek, it is highly possible 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 Subaru Crosstrek, 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 automobile 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.
