This seal is moistened with coolant during forward travel. As a result of the change in rotational direction when reversing slowly, it may be the case that this sealing ring is no longer moistened. Squeaking noises may occur as a result of the so-called \"stick-slip effect\". This behavior does not impact the function or durability of the sealing ring and electric drivetrain. Remedy Do not replace any parts. Explain the cause of the noises to the customer.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10231022-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10231022-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10231022","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES","model":"EQB","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG EQS","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"EQB 300 4MATIC","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"EQE","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"EQE SUV","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"EQS 450","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"EQS 580","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"EQS450","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
