Hi, I found this thread using Google and have the same issue, except now worse. The child lock on the rear right door of my 2013 Crosstrek was stuck in the engaged position. The child lock on the rear left door worked without issue, so I pushed on the right lock and the plastic switch snapped off (photo).
The is the first trouble I've had with my Crosstrek, but is seems to be a common issue on other Subaru models based on forums I have read.
Has anyone managed to repair a stuck child lock on a Subaru? If so, please share.
