CSC failure covered under warranty?

Having the same issue and nissan is refusing to cover the repair . The woman from nissan didnt want to hear anything she just keep repeating why it wasnt covered . I asked about an appeal and she said I could mail a letter to nissan consumer affairs
The previous owner had the exact same problem at 30000mi and the dealer replaced the fluid and sent him on his way . I now have 38000 mi. The previous dealer is far north of me ,too far to go The pedal is about half way down and it dosnt look like much fluid is missing . Also no leaks under the car . The dealer says its prob just the master
Looking for advice on how to proceed.
