# Service bulletin NCU\-2023050005

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 Model Year \(“MY”\) 2014\-2020 S\-Class \(217 and 222 platform\) vehicles, the incorrect pilot bushings may have been installed in the front axle tension struts. It is possible that noises and an increased wear of the pilot bushings may occur. MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will check the pilot bushings on the front axle tension struts, and replace if necessary.
