# Service bulletin SSM 50872

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

Some 2020\-2022 Aviator vehicles may exhibit an issue transitioning to night mode in low ambient light conditions. This may be due to accessory protocol interface module \(APIM\) software. Inform customers that engineering is currently working on a solution for this condition and will be released via an over the air \(OTA\) software update expected in July 2023. Software will update automatically if the vehicle is connected to LincolnWay. Monitor OASIS for additional information. Schedule a service appointment for customers that are not connected to LincolnWay once the repair becomes available.
