Does the Sub not power up at all?

I’m astonished they can’t offer you some kind of deal, even if it’s for a refurbished replacement.

Me too.  In the past they have been fairly generous in their treatment of just-out-of-warranty failure.  (Bearing in mind that any concession is beyond their legal obligation.)  I would try again and argue your case.

The technical advisor told me that they would not exchange it , but since then I have received an email saying they would exchange it ..

so I’m fingers crossed at this point .
I am quite tech savvy and tried every thing that it could possibly be ., take my word for it ‘ It’s as dead as a Dodo 

Glad to see you got some traction from Sonos to make things right. I too was surprised at their first response.

Happy to say Sonos have replaced the faulty Sub at no additional cost ...

For only two years I enjoyed the sound quality from my Sonos system only to find for absolutely no reason whatsoever last night, the Sub quit working... Strange right? it has been in the same place on the same settings since I bought it. All of a sudden, no lights, no power, nothing... Contacted support and ran through a bunch of troubleshooting options only to confirm, the sub power supply is dead. Wow, only after two years. I've never abused the system, the sub has always been in a well ventilated safe place - this must be a one off right? A faulty sub? Wrong!!! This is a very common problem. Not usually after two years, but the sub eventually craps out. No big deal, Sonos will step up to the plate and support their product right? WRONG AGAIN!!!! Sorry sir, you need to replace it at a replacement fee of $530. I appreciate the discounted price, however, how can you possibly feel this is acceptable after only two years? The product was registered December 2018. For those who are contemplating adding a Sonos system to their home theater, look elsewhere, save yourself a ton of money, these units are designed to fail after the warranty expires. They understand that the replacement value is still cheaper than replacing the entire system and the capitalize on it. Stay away, do not purchase Sonos, there are far more reputable companies that will stand behind their product. Sonos, you should be ashamed

Hi Jo ., that’s exactly what happened to my Sub which was Registered end of November 2018..

must have had a Duff batch around then..

but I complained to them and they send me a reconditioned unit free of charge ..

They used UPS As a courier who made me jump through hoops in order to send back the faulty unit , but got there in the end ..

keep on  at them 

Thanks everyone for your feedback. Every person has their own opinions and community forums are not meant to discredit ones experience. Each consumer is entitled to their own degree of expectation when purchasing items and these forums are meant to share thoughts. My post was clearly written out of frustration and I would render most consumers sharing the same experience as I had would be equally dissatisfied. Not by any stretch of the imagination do I expect electronics, or technology to last forever. But as I do, we all expect there to be a level of quality. I won’t get into commenting on all the “what if’s” and opinions posted here, but I wanted to let everyone know that I escalated this beyond customer care. I am pleased to share that Sonos support did step up and back their product. They have issued a replacement for the sub at no charge. I do believe in supporting brands and companies who go above and beyond. Rather than leave this tread to stew in negativity, I wanted to provide the feedback from Sonos and share that the issue has been resolved positively. I’m hoping this is a rare issue and looking forward to many more years with my system. Thanks and stay healthy.

Let me add my 2 cents worth - mine just died as well (November 2018). I have 12 sonos products in my house and have been an early adopter of these (bought them in 2011) - one amp has died and the rest are fine. I have two subwoofers and the older one works, and this one (the newest of all my sonos purchases does not work).

Its a shame that these components dont work as long as advertised. The house has marantz amps for the TVs and NOTHING else has broken. 

Sonos - you are going to make me pay $$ for a replacement on something that should not break. 

Not happy about this.

The person who helped me was nice - so I cant complain about her - but its not something that gives me comfort.
