When does my Chevrolet HHR make a loud noise?
One way to discover a noise from your Chevrolet HHR is to establish when it occurs. Indeed, some complications can be linked to parts that are only stressed under certain conditions. It is this process that we will focus on in this first part.
Loud noise Chevrolet HHR when accelerating
Loud noise on Chevrolet HHR that starts when you are accelerating can be symptomatic of multiple failures. Indeed, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will cause a much higher noise than during normal process. In addition, it is also highly plausible that loud noise on your Chevrolet HHR is linked to a wheel bearing, which is one of the most common causes of these types of symptoms. Another alternative 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.

When my Chevrolet HHR is stopped

The loud noise comes from the wheels of my Chevrolet HHR
As we have seen previously, loud noise from the wheels of your Chevrolet HHR may be connected to two main problems. 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 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 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 Chevrolet HHR that is the matter, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your auto mechanic to swap the tires or execute a balancing.

The loud noise comes from the engine of my Chevrolet HHR
In case you have identified loud noise as coming from the engine of your Chevrolet HHR, 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 encounter a power loss during your acceleration. If the loud noise on your Chevrolet HHR 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 induce 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 perceived comes from the exhaust pipe of your Chevrolet HHR, it is highly plausible 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 HHR, 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 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.
