The loud noise comes from the wheels of my Buick Envision
As we have seen before, loud noise from the wheels of your Buick Envision may be linked to two main complications. 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 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 swap it or them right 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 Buick Envision that is the issue, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, you will have to go to your mechanic to replace the tires or perform a balancing.

The loud noise comes from the engine of my Buick Envision
In case you have recognized loud noise as coming from the engine of your Buick Envision, 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 experience a power loss during your acceleration. If the loud noise on your Buick Envision 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 disorders, take your car to your mechanic .

To confirm this, get help from someone who will stand under the car while you accelerate to find the exact area of origin of this noise.
