Check Right Mounting Support
for Cross Strut on Underbody
This is to notify you of the Service Campaign Launch to check the right mounting support for the cross strut on the underbody
on 1,163 Model Year (“MY”) 2021 205, 213, 238, 257, and 290 (C-Class, E-Class, CLS-Class, and GT-Class) vehicles. The
vehicles will be visible and flagged in VMI as “OPEN” on September 17, 2021.
Background
Issue
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined
that on certain MY 2021 C-Class, E-Class, CLS-Class, and GT-Class (205, 213, 238,
257, and 290 platform), the right mounting support for the cross strut on the
underbody might not correspond to current specifications. It is possible that the
mounting support could be cracked.
What We’re Doing
MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will check
the right mounting support for the cross strut on the affected vehicles and treat the
crack with cavity protection wax, if necessary.
The Remedy is available and can be performed as necessary. Replacement rate
is ~1%.
