Check Front Axle Tension Strut Pilot Bushings

This is to notify you of the Service Campaign Launch to check the front axle tension strut pilot bushings on 56 Model Year (“MY”) 2014-2020 S-Class (217 and 222 platform) vehicles. The vehicles will be visible and flagged in VMI as “OPEN” on June 23, 2023.



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.


What We’re Doing

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.



The remedy is available and can be performed as necessary.
