Revised Service (Updated expected release date)
Customer states:
 Last destinations, favorites, and home/work addresses are sporadically lost.
Workshop findings:
 The concern might not be reproducible at the dealership due to it happening sporadically.
Technical Background
A software bug can cause some user data to be lost on boot-up.
Production Solution
This bulletin will be updated when more information is available. A solution is currently under development.
Service
1. Explain to the customer that a solution is forthcoming for the 3rd quarter of 2022 and that no repairs are
necessary at this point. A workaround procedure will become available by the end of 2021, by which time this
PSS will be updated with that procedure.
Do not replace any components for this condition since this will not resolve the customer’s concern.
2. Create a PSS record in the PSS application through the Pending Service Solutions (PSS) link in AccessAudi
(under Related Links >> Service), or through the Technical Assistance page in Elsa.
