Bulletin Summary
Mercedes-Benz AG (âMBAGâ), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2020-2021 GLA-Class and GLB-Class (156/247 platform) vehicles, the transmission bearing cap cover does not correspond to current specifications. Over time, the transmission bearing cover may loosen, which may result in minor oil loss. An instrument cluster transmission light will still alert the user if it falls below the threshold and alert the driver if the transmission oil overheated. The indicator light will alert the driver to drive with caution. A risk of fire can be ruled out. What Weâre Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will replace the transmission bearing cover.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
