Service bulletin A21120A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

ServiceNews Article - The clock shows the incorrect time. This issue is due to a limited GPS receiver capacity resulting in "rollover" of the internal chip memory; the "rollover" will occur on January 1, 2022, at 12:00AM local time. As a result, once specific triggers are met, the navigation date and time will be incorrect.
