This has never happened before, but while I was driving around today, the engagement point changed couple of times by itself. Sometimes it would be normal (high off the ground) and sometimes it would right off the floor...like a civic's clutch.

Anyone have any idea what this might be about?

 

I am going through this now. I think it is the master cylinder, i am going to replace it soon to see if that is it or if it is the slave cylinder. if it is under warranty, bring it to the dealer and have them fix it and tell me which fixed it! good luck!
