Service bulletin NCU-2020090002

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Mercedes-Benz AG (?MBAG?), the manufacturer of Mercedes-Benz, has determined that on certain Model Year (?MY?) 2020 GLS-Class vehicles (X167 platform), the stop plate on the front axle suspension struts may not have been installed correctly on the support ring. It is possible that the vehicle level may lower to that of the bump stops.
