first sold: 10/2008
pump started to fail: 26,000 miles (10/2012)

* both Eastern Iowa Mitsu dealers have said that the pump is not covered by the 5-year PT warranty

pump started to fail: 38,000 miles (11/2012 ) <-- guestimate
pump failed: 40,000 miles (02/2013)
cold-start reflashed: yes right when it was made available

Powertrain warranty up next month and i'm still fighting with the dealer to get them to cover it under warranty. Fuel pump is covered under powertrain, water pump covered under powertrain but not AYC pump wtf :/

Evox forums also has a compilation list http://www.evoxforums.com/forums/showthread.php?t=58221

Pump started to fail: 86600 miles message popped up with it being extremely hot out. Not sure if that means the pump is actually failing or if it just needs service in general.<br />
Pump failed: hasn't failed yet and the system works fine when the temperature is below 90 degrees or so.<br />
Cold-start reflashed: Never
