I think the bathtub model applies here. This model is a graph in the shape of a bathtub that shows how long a product keeps working.

Some products are manufactured faulty, so break within the first shiort period. Then there is a period with no breakages, followed by a period where the product will break from "old age"

Sorry for bad English
