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.
Safety Consequence
If the anchoring bar is missing from the ISOFIX bracket, the child restraint cannot be properly secured to the seat using the ISOFIX securing system, increasing the risk of injury for a child in that seat.
Remedy
MBUSA will notify owners, and dealers will inspect the right-rear ISOFIX bracket and replace the bracket, if necessary, free of charge. The recall began March 16, 2021. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2021020004.
