I questioned him if the updated pump has steel plungers he lead me to believe that improvements to the plungers were made but he thought they were still ceramic ?

Total waste of time to call a stealership or OEM shop and ask those questions!. They can tell you roughly what was done under warranty, but seriously have NO CLUE what is in your engine!

If the pump was replaced completely in 2014, then perhaps you are lucky and have steel plungers,.. but the only way to know for sure is to take it apart and see.

Myself, I am not a gambling type, so as that pump gets 400k miles or on it, it is time to open it up and replace its guts any ways, steel, ceramic, whatever it has in it.
