Service bulletin NAS21.11.014

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

A potential issue has been identified on specific vehicles where, in locations where the vehicle has poor or no network connection, vehicles may experience intermittent resetting of the navigation system, following a recent Map Over The Air (MOTA) update. The navigation screen displayed on the Touchscreen will revert to the PIVI home screen and the navigation screen displayed in the instrument cluster panel will revert to displaying the manufacturer's logo. The system will self-recover and navigation will resume, however this fault may re-occur if the vehicle maintains poor or no network connection. No other vehicle features or systems are affected.
