Official summary

Mercedes-Benz AG (MBAG), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2022 GLE and GLS (167 platform) vehicles, corrosion on the solenoid may occur in the electric coolant pump. In this scenario, a yellow coolant warning lamp may be shown in the instrument cluster. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will inspect the electric coolant pump and replace it, if necessary.

Vehicles covered

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
