I'd go into the dealership(same one or different one) immediately complaining about the transfer case and state all of the symptoms whether you have it or not. Tell them that you know its transfer case problem from your research and it is under warranty and you'd like to have it replaced as such. Go straight for the jugular. Good luck and let us know what you do.

Also said it is entered into their system so any P dealer could see it. It included the claims process if I had paid for repairs before and wanted to be reimbursed.

Now I am at 56k miles and it looks like it is failing again. How is this possible? It is my wife's car and we do not drive fast or even much really. Average 5 to 6k miles a year. I also noticed some people have a 10 year warranty while the 2016 -18 is 7 years. Why is that? From the symptoms, I initially thought my power steering was acting up so I replaced the fluid in that about 6 months ago. What can I do to get Porsche to cover the replacement. It seem crazy that the same part can fail in 35k miles. I do not even recall getting a letter regarding this issue from Porsche. I am now reading from this forum the fluid should be changed every 1-2 years or every 10-20k miles but the dealership or anyone from Porsche is not stating that. I would have done so if i knew. Why is Porsche getting high reliability scores with such a big issue. Also why is there never a recall on the TC?
