# Service bulletin SSM 49885

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.

- Type: Service bulletin
- NHTSA id: 10198640
- Published by NHTSA: 2021\-07\-02
- Manufacturer's number: SSM 49885
- Manufacturer's date: 2021\-06\-14
- NHTSA component: EQUIPMENT

## NHTSA's summary

Some 2019\-2021 Ford and Lincoln vehicles may exhibit an intermittent audio echo/robotic voice heard during a bluetooth phone call by the person that is not in the vehicle. Using Apple CarPlay and Android Auto instead of Bluetooth can help alleviate the concern. Also turning on, then off, the privacy setting in the SYNC touchscreen can temporarily alleviate the concern. Engineering is currently investigating this concern and will be releasing a service fix in early July 2021. Let the customer know they can continue to drive the vehicle and schedule service appointments for customers once the repair becomes available. Monitor OASIS for updates.
