Loud noise Cadillac XT5 when accelerating
Loud noise on Cadillac XT5 that occurs when you are accelerating can be symptomatic of multiple 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 generate a much higher noise than during normal use. Moreover, it is also highly plausible that loud noise on your Cadillac XT5 is in connection with a wheel bearing, which is one of the most common causes of these types of symptoms. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

The loud noise comes from the wheels of my Cadillac XT5
As we have seen before, loud noise from the wheels of your Cadillac XT5 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 consider to check 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 as soon as possible. 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 Cadillac XT5 that is the trouble, 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 auto technician to change the tires or accomplish a balancing.

The loud noise comes from the engine of my Cadillac XT5
In case you have identified loud noise as coming from the engine of your Cadillac XT5, 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 encounter a power loss during your acceleration. If the loud noise on your Cadillac XT5 is related to air intake, the check 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 cause an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then check that the engine idle speed is not random. In case you confirm one of these two disorders, take your vehicle to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Cadillac XT5, it is highly plausible that you have rust if your car is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Cadillac XT5, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure this, get help from someone who will stand under the car 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.
