This video here is exactly what my car sounds like. I recently did an oil change on the car, but did NOT use full synthetic oil. Could that be the problem? Thanks

bump

also have a similar problem,
not as noticeable and happens on and off. (usually after being driven for more than 40 min)

I also just got a synthetic oil change. What oil did you use?

mobile 1

what weight?

5w30

Air Conditioner Compressor bearings. Common issue on our cars.

Try this, Turn off your climate control and see if the noise changes or stops.
Oh - I noticed mine quieted way down once I changed the Drive belt. Have you changed your Serpentine/drive belt? It needs to be changed every 40-60,000 miles.

I tried turning the climate control off it didnt help. I haven't changed the serpentine/drive belt actually, but i know i need to. Does it make a change in engine bay sound dramatically?

Could be the belt or a bearing the belt rides on that is out of balance, causing a whining noise.

It is similar to a wheel that has a damaged wheel bearing, so it would whine as it rotates. It could be a fan? It sounds like a rotating noise.

Sounds like a bearing / belt. Could be a bearing on, water / power steering pump?

I had a whining/squeal sound at idle and acceleration and a new belt took care of it. Worth a shot if it needs to be done anyway

For me it did. Also you have to change i anyway, if you are past 60,000 miles you should change it, otherwise you risk it snapping/failing on you anyway...not a good thing.

I have this exact same issue, that video posted is EXACTLY what it sounds like. It just started a couple days ago... I will look into the belts and see if that is the issue and will post an update.

I have that same sound with my '07G coupe. It just started a few days ago. OP, did you ever solve it?
