Ya mine started leeking for no reason as well but I notice it only leaked when I parked in drive way at a slant but doesntw hen I am level. I looked didnt see where was comming from. Well didnt do through look really well just qucik check. Well couple days now its gone <shrug>even when I do park back in the drive way. I may replace hoses just in case to be on safe side. It is odd all of a sudden it started leeking and yeah I went up and down some hills myself but that was awhile back.
