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 vehicles, has determined that on certain MY 2020 A\-Class \(177 platform\) vehicles, the ATA control unit coding may not correspond to the current production specifications. As a result, the interior sensors may not function as intended and could result in blind spots for interior vehicle protection. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will update the ATA control unit coding.
