The loud noise comes from the wheels of my Chevrolet Bolt
As we have seen before, loud noise from the wheels of your Chevrolet Bolt may be linked 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 consider 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 replace it or them straight away. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Chevrolet Bolt that is the problem, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your auto technician to change the tires or accomplish a balancing.

The loud noise comes from the engine of my Chevrolet Bolt
In case you have discovered loud noise as coming from the engine of your Chevrolet Bolt, 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 Chevrolet Bolt 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 car 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 Chevrolet Bolt, it is highly possible 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 Chevrolet Bolt, 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 vehicle while you accelerate to find the exact area of source 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.
