Over-the-air update N25-249646
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.

This software update includes the following, if your vehicle is equipped: • Enables Dolby Atmos advanced surround sound technology to provide optimal, immersive audio experience. • Introduces Atmos object-based audio to allow sound to be placed throughout the vehicle. • Utilizes height channels to allow sound to move in a three-dimensional space with Atmos. • Active OnStar Services plan or data plan required. • Amazon Music Unlimited and Tidal currently available for use with Atmos. • Compatible streaming services that default to the highest quality track supported will utilize Atmos. • Atmos content in .mp4 format can be played from USB storage devices.
