Normally you might change those parts once through the life of the vehicle. If they are actually failing that often there is probably another problem causing their failure. Something like a bad engine ground or wiring fault causing issues in the system.
Do you get to see the "bad" parts or have a picture of them so we could see how they failed?

What is the actual code are they getting, not their translation? Where have you been buying the parts?
