When does my Scion tC make a loud noise?
One way to discover a noise from your Scion tC is to define when it occurs. Indeed, some problems can be connected to parts that are only stressed under certain conditions. It is this approach that we will focus on in this first part.
Loud noise Scion tC when accelerating
Loud noise on Scion tC that occurs when you are accelerating can be symptomatic of several failures. In fact, if you experience 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 process. In addition, it is also highly possible that loud noise on your Scion tC is connected to a wheel bearing, which is one of the most common causes 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 increases speed.

When my Scion tC is stopped

The loud noise comes from the wheels of my Scion tC
As we have seen before, loud noise from the wheels of your Scion tC 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 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 change it or them as soon as possible. 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 Scion tC that is the problem, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both circumstances, you will have to go to your technician to replace the tires or execute a balancing.

The loud noise comes from the engine of my Scion tC
In case you have recognized loud noise as coming from the engine of your Scion tC, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected 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 Scion tC 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 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 Scion tC, 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 Scion tC, 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 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.
