Summary
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined that in certain MY 2020 A-Class and GLB-Class (177 and 247 platform) vehicles, the contact surface of the upper hinges to the B-pillar on the right and left rear doors may have been arched. As a result, water could intrude into the gap between the Bpillar and door hinge, which may result in corrosion. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will rework the upper hinges of the B-pillar on the left and right rear doors.

Owners of these vehicles have filed 15 complaints in the body category.
