Service bulletin SC-202203005

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 MY 2015-2018 C-Class and GLC-Class (205 and 253 platform) vehicles, the software for the powertrain control unit may not correspond to the current production specifications. It is possible that the next maintenance interval is displayed to the user as a negative distance reading in the instrument cluster. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the powertrain control unit software.
