I don't know if you got a reply to your question so I will just add my two cents by saying if you have an extended warranty, it is good for 7 years or 75,000 miles. I don't know of any warranty that goes further.
For non-California cars the hybrid system factory warranty is 7 years/100,000 miles. The factory warranty on other components has expired. It is too late to buy an extended warranty, if that was your question.
