I have three Polk I-Sonics. I have lost count but I'd say that I've had to have each replaced two or three times. The oldest is nearly a year old while the newest is about six months. 
Some of the earlier replacements were for "ticking" on the CD/DVD transport. It's loud and is irritating if you're playing it at low volume or are sitting close to it. That problem has never been solved however some units seem louder than others.
Other problems have included the CD volume going down to nearly nothing while the radio section worked fine. Another had a complete failure of the unit, leaving the clock stuck at 12:00.
That being said, Polk Audio has been very responsive in replacing these units. I hope they are because two more are now down for the count again. I e-mailed them yesterday requesting replacements.
Am I just unlucky or are there widespread problems with this unit? I run all of my I-Sonics on either a high-quality UPS or surge protector.
