6 injectors replaced! Why did they fail?

My car was misfiring in cylinders 5 and 6 and so the dealership decided to replace all the injectors under CPO warranty.
My question is, why are the fuel injectors failing? Aren't they supposed to last the life time of the car?
(and why does it seem like cylinders 5 and 6 are always the most problematic? )
