# Service bulletin NCU\-2023030004

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 2022\-2023 SL \(232 platform\) vehicles, the software of the rear control unit may not meet current production specifications. Therefore, the possibility exists that the soft top may not close from the “soft top open” position. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will check and calibrate the roof frame outlet flap, if necessary.
