What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationPicked out of NHTSA’s summary below, word for word. The document itself is the record, and the dealer checks the VIN.
Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2023 CLA (118 platform) vehicles, the upper area of the fender may be in contact with the side wall due to sheet metal burr. Therefore, the surface coating of the fender and side wall may become damaged, which could lead to corrosion. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will check the top of the right and left fenders at the A-pillar paneling and rework them, if necessary.
