# Service bulletin NCU\-2023050002

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 Model Year \(“MY”\) 2023 GLC \(253 platform\) vehicles, the seam seal on a small portion of the right A\-pillar does not correspond with current production specifications. It cannot be ruled out that a leak may occur due to an inconsistency in this seam seal. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will repair the seam seal at the A\-pillar.
