I have to use the manual release to unlock a cable at a non-Tesla charging station the other day. After pulling the string twice it felt like it was detached from wherever it was supposed to be. I have a mobile service appointment booked to fix it. To my surprise, although my car is still under warranty the estimated out-of-pocket costs are estimated to be AUD $770.00 (equivalent to about USD$550.00).
A search of people who came across similar problems led me here. Looks like I am the only one with this bill shock. I hope when the technician come, they only need to re-attach the cable and I don't have to replace the whole thing.
