How to accelerate CSC failure

greenlawnraci

I don't know that accelerate is the right word, but I want to make sure it is cared for under warranty. Yes, I know that I'm better to spend some money and buy an aftermarket one. However I'd at least like to start with a brand new one on Nissan's dime given that failure is immanent:

My car only has 39K on it., and rarely gets driven. Warranty (factory extended) goes until April.

Slave cylinder is STARTING to fail, just like my other nine Nissans. Loses pressure sometimes, if you hit the pedal a few times it gets pressure again. I’m fully confident it will fail again, just like all of my other Nissans.

Called the dealership today, they confirmed that it has to be in total failure to replace. Last time this happened I’d drive right to the dealership…..but enough driving and usage of the clutch on the way to the shop would give it sufficient pressure and the dealer then could not replicate the issue.

Any advice or ideas for how to show/put it into total failure? Last time I had to wait until it was really bad, pull over immediately, and call a tow truck. Unfortunately I don’t drive enough to see that happening before April.
