I have my E-PL2 for 3 years now, still works good as new. Either their reliability really went downhill after their success with M4/3s or you are really unlucky, man.
Actually most cameras last much longer before they are sold nowadays , but being electronics it's definitely a sad truth that a small % may fail within the warranty periods.
Even a car costing more than $100,000 will also fail.
Just get the system sent in to Oly and have it checked and fixed , it's never enjoyable when this happens but I'm glad in a sense that the camera is within warranty.
