Service bulletin SC-2022060006

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2020-2021 CLA-Class and GLA-Class (118 and 247 platform) vehicles, the engine coolant line may leak due to high pressure within the engine coolant system. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will replace the corresponding coolant line on the affected vehicles
