In this case, the flex disk may have been exposed to high temperatures from the exhaust system. As a result, the connecting screws could tear loose from the flex disk, resulting in knocking noises from the rear axle. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will replace the flex disk and install an additional heat shield.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11011845-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11011845-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11011845","components":[{"id":"structure-body","name":"Body and frame","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG CLA35","year_from":2020,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA45","year_from":2020,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA 35","year_from":2024,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA 45S","year_from":2024,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA35","year_from":2021,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA45","year_from":2020,"year_to":2023,"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":"CLA 250","year_from":2020,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLA 250","year_from":2020,"year_to":2024,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
