The loud noise comes from the wheels of my Toyota Sequoia
As we have seen previously, loud noise from the wheels of your Toyota Sequoia may be in connection with 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 examine 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 right 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 Toyota Sequoia 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 mechanic to swap the tires or accomplish a balancing.

The loud noise comes from the engine of my Toyota Sequoia
In case you have identified loud noise as coming from the engine of your Toyota Sequoia, 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 experience a power loss during your acceleration. If the loud noise on your Toyota Sequoia 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 examine that the engine idle speed is not random. In case you confirm one of these two problems, take your automobile to your service garage .
