Service bulletin SC-2022020003

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 in certain MY 2021 GLS-Class (167 platform) vehicles, the SCN coding in the “electronic ignition lock” may not correspond to the current production specification. In rare instances, the vehicle may lock unintentionally while the vehicle key is still within the vehicle. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the SCN coding for the “ignition lock” control unit on the affected vehicles.
