Took my 2020 ST in for the 36K maintenance and Recall issues. The door switches sharp chrome tip replacement, 22N17 Recall, was not a problem, but the Rear camera Recall 23S23 was not completed due to software upgrade not completed because of errors. Service advisor stated they are waiting for a patch to remedy the software errors. This problem is present on two other STs they were trying to install the Recall 23S23 on. I was told the fix should be available next week because Ford is working on this software error. I wonder what is going on, are the technicians struggling with this new software upgrade procedure or is Ford really trying to push this recall out too early.
