Service bulletin NCU-2020080013
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
Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz, has determined that on certain MY19-21 CLA-Class, A-Class, GLA-Class and GLB-Class (118, 177, and 247 platform) vehicles, an increased electrical resistance may occur between the connector block of the electronic control unit and the connector pins for the Supplemental Restraint System (SRS) wiring harness. The SRS control unit might detect the increased resistance in various SRS circuits (e.g. driver/ front passenger airbag, seat belt tensioner) which could lead to illumination of a warning message (yellow) and a warning lamp (red) in the instrument cluster. The functionalities of the SRS system are not impaired.
