Personally I'd contact Subaru Customer Relations and open a file.
Explain the situation as you have here. Ask them to explain what is covered under emissions warranty. They may press for a goodwill gesture from the dealer. I believe anything related to emissions is covered under the standard warranty and some parts even longer, diagnostic charges should be included in any warranty work.

When you took it to AutoZone they most likely cleared the code. Was your engine light was off? What I don't know is, are codes that have been cleared still stored or are they gone until the problem causes another code?
If the code was cleared and unable to be reread, than the diagnostic fee might be justifiable in my opinion but still should be covered under emissions warranty not at your expense.

Interesting to hear what other members think. Good Luck and keep us posted.

most autozone and advance code readings i have obtained were accompanied by a refusal of the employee to reset the computer and clear the codes. a couple of times an employee allowed me to push the button to clear the code but he would not do it himself. store policy i was told.

Good to know, thanks
