Adjustment via the seat adjustment switch is still possible. Example: Driver 1 parks the vehicle in the evening and the seat position is right to the front with Memory button 1. Driver 2 opens the driver's door and presses Memory button 2, as seat position 1 is too far forward to get in. The seat does not move to the saved rear seat position 2. Once the ignition is turned \"on\", the function is available again. Cause The cause is an error in the HU7 software. Remedy Please perform a software update in the HU7 control unit and then carry out a factory reset of the HU7.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031205-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031205-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11031205","components":[{"id":"seats","name":"Seats","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG GLC43","year_from":2024,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLC43 4MATIC","year_from":2024,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLC43 4MATIC COUPE","year_from":2024,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLC63 S E","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLC63 S E 4MATIC+","year_from":2025,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLC63 S E 4MATIC+ COUPE","year_from":2025,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC 300","year_from":2023,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC 300 4MATIC","year_from":2023,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC 300 4MATIC COUPE","year_from":2024,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC 300 COUPE","year_from":2024,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC 350 E 4MATIC","year_from":2025,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC43 4MATIC COUPE","year_from":2026,"year_to":2026,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
