I have attached a file, (not sure if it got stuck)
The loud hard buzzing from the AC compressor is strange next to hearing some hissing noise from the air vents when AC compressor kicks in.

But the buzzing is what have made me wonder if there is something wrong with AC or will go wrong soon.

It is exactly like this one


From what I have gathered so far my AC compressor serial number is what a bulletin says to be replaced.

Have anyone else experienced similar situation

My 2017 XT is making the same noise with no cool air. Taking it in next week. Any news from above?

Did you ever sort the AC compressor buzzing out? My 2014 XT is exactly the same, hoping to get it sorted but would like to know exactly what causes it. I'm hoping it is just low freon levels.

Likely a condenser leak causing low r134a pressure. The condenser warranty has been extended to 5 years due to lots of 2017 failing.

agreed, exactly. my 2017 XT had a condenser leak last month, and during that time, the compressor did still engage but it was noisier than normal

You are right. That was fixed by Subaru HQ after a call in spite of expired warranty. I posted this on another thread. Thought the moderators merged all the posts.

Good to hear. Did they change the compressor or was it repaired?

You got lucky. I contacted dealer and SOA and even though my mileage was less than 36000 they both stated my 36 months were up by about 3 months and there was nothing they could do. So I had mine repaired by a independent ac specialist for about $360. Had I taken it to Subaru dealer, which was about 100 miles away, i would be out the travel,plus around $800-$1000, plus a rental vehicle to get me back home and to and from work until the dealer fixed the issue. Really not happy with Subaru. The independent mechanic, filled up r134, added dye, let me drive it and in one day brought it back, confirmed condenser leak. Ordered part and fixed my problem. I was only actually without my car for about 5 hrs.

I understand that Subaru America has extended warranty for the 2017 AC to 5 years recently. Perhaps you can check if you can get a reimbursement. Check the recent postings on Subaru AC problems.

Yep I filled out the form for reimbursement, but have a feeling that since a dealer didn't do the repair, they will balk. Maybe not.

I posted a video about my same issue in a thread a while back. Same loud compressor noise and no cold air. They found a leak and replaced the condenser. I guess the clutch gets loud like that when it's low on refrigerant.

I went to a Denso repair shop today and they looked at the compressor. They didn't do any more than look and listen and they said I need a new compressor. My AC is still cold so I guess that rules out a leak on my condenser? Not sure what to do now as my AC is okay but the buzzing is very annoying, not sure if I want to spend on a new compressor just to stop a noise you can't even hear inside the car.

I've never done it myself, but I think that a/c maintenance equipment gives an easily measurable reading of the content of refrigerant still onboard your car. If the pressure in the system is high enough, nothing can have leaked out. If the pressure is lower, there has been a leak. Your description doesn't sound like they did this. On the other hand, it certainly isn't impossible that compressors can fail in ways that don't cause leaks (at least at first), but if that's your case, I would imagine you will soon learn more.
