Summary

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined that on certain MY 2019-2021 G-Class, S-Class and GT (463, 222 & 190 platforms) vehicles, the engine control unit software does not correspond to current production specifications. It is therefore possible that onboard diagnostics and/or exhaust gas emissions requirements may not be fulfilled. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will perform the ECU software update.

Owners of these vehicles have filed 9 complaints in the engine category.
