Update: I recently posted in here believing I had this issue but I just pumped in and replaced my clutch fluid and haven't had one single issue since then.
Before changing fluids the pedal was squishy after 30min of highway 80mph driving, just cruising. Now the pedal remains consistent no matter how hard I push the car
Some of you lurkers may want to swap your clutch fluids BEFORE you have these issues. I had the same symptoms and perhaps I fixed the issue before it became a CSC failure. .....I hope.
