Summary

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year 2021 C-Class (205 platform), CLA (118 platform), G-Class (463 platform), GLC (253 platform), GLA (247 platform) and GLE/GLS (167 platform) vehicles, the installed ignition coils may not correspond to current specifications. As a result, a misfire could occur, followed by potentially reduced engine output, and illumination of the check engine Malfunction Indicator Lamp (‘MIL’). This may also cause exhaust emissions to increase. MBUSA will conduct a voluntary Emissions Recall Campaign in which an authorized Mercedes- Benz dealer will replace the ignition coils.

Owners of these vehicles have filed 94 complaints in the engine category.
