Am I missing something here? Can you imagine the uproar if one in fifty iPhones had to be returned, or one in fifty PS4s, or one in fifty Xbox Ones - oh, awkward.
the xbox 360 had a 23%-54.2% failure rate

iPhones have about a 5% failure rate, but that includes accidental damage (as far as I can see Apple count that as a failure).
Technology is much more reliable then it was a while ago. It'll never be perfect though. I think 2% is perfectly reasonable as it also will take into account user error.
