Service bulletin NCU-2023030017

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 2022-2023 SL (232 platform) vehicles, the software of the left and right rear axle steering control unit does not meet current production specifications. As a result, a rear axle steering fault message might sporadically appear in the instrument cluster during engine start. The vehicle continues to be operational and safe to drive should the message appear. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the software on the left and right rear axle steering control unit.
