Over time, the transmission bearing cover may loosen, which may result in minor oil loss. An instrument cluster transmission light will still alert the user if it falls below the threshold and alert the driver if the transmission oil overheated. The indicator light will alert the driver to drive with caution. A risk of fire can be ruled out. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will replace the transmission bearing cover.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10228824-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10228824-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10228824","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG GLA35","year_from":2021,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA45","year_from":2020,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA45 S","year_from":2021,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLB35","year_from":2020,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLA 250","year_from":2020,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLB 200","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLB 250","year_from":2020,"year_to":2021,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
