As NHTSA's recall record states it for campaign 21V034000.

Defect description

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2021 A220, A35 AMG, and CLA250 vehicles. The child seat anchoring system (ISOFIX) may be missing the right-side anchoring bar from the ISOFIX bracket on the right-rear seat.
