40K mile service for the wife's CX-5 last Saturday, well 41K to be exact. Turns out the piston on the belt tensioner was leaking. That was fixed but it was costly at almost $400 for parts and labor. Unfortunately it wasn't covered by the powertrain warranty because it is supposedly a wear item. I still think that is stupid, especially a part that is leaking at only 41K miles, but whatever I wouldn't be able to fix it on my own anyway. The car does feel better to drive after though. Getting close to getting the CX-5 paid off which is exciting!
