Have you had any really, and I do mean really rough starts in the morning where the car sounds like its chocking and then you get a CEL light? If you haven't had that yet, even though it cranks for a bit at startup, they (Dealer) won't replace it because the pump is passing the diagnostics, therefore, they won't change it.
When I went to the dealer, I went with video proof and showed them all the times I got a CEL. When they did the second round of diagnostics on the pump since they knew I had the software. The pump failed on the initial pressure buildup. That was why minie got replaced.
I would do some recordings in the mornings if I was you. It helped me alot.
