Summary

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined that on certain Model Year (“MY”) 2016 – 2021 C-Class (205 platform), E-Class (213 platform) and GLC (253 platform) vehicles, the air conditioning control unit software may not meet production specifications. There is a possibility that a stuck open thermostat may wrongly be detected causing the check engine Malfunction Indicator Lamp (‘MIL’) to illuminate. MBUSA will conduct an Emission Service Campaign. An authorized Mercedes-Benz dealer will perform a software update to the air conditioning control unit on the affected vehicles.

Owners of these vehicles have filed 87 complaints in the visibility category.
