Summary

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2020-2023 CLS (257 platform), E-Class (213 and 238 platform), GLE (167 platform), and AMG GT 4-Door (290 platform) vehicles, the engine control unit software does not correspond to current production specifications. As a consequence, the functionality of the post-catalyst oxygen sensor may be impaired due to increased thermal loading. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the engine control unit software.

Owners of these vehicles have filed 129 complaints in the engine category.
