Service bulletin B611808
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
BATTERY MAINTENANCE REQUIREMENTS: BATTERY CARE. Proper battery maintenance is vital when BMW vehicles are in your center's inventory. Allowing a vehicle's battery voltage to drop below 12.0 volts (12.0V) permanently reduces the battery life expectancy and can lead to premature failure of the battery. For vehicles, equipped with a high-voltage battery (hybrid/electric vehicles), failure to properly maintain this battery may lead to a greatly discharged HV battery, requiring replacement.
