In specific situations under various independent ambient conditions, this detection could be activated by mistake, with the result that the wiper system switches from activated continuous operation to intermittent operation when it's raining. Cause Sensitive parameters for detecting dry conditions. The wiper system might switch back to intermittent operation even though it is raining and continuous wiping is activated. Remedy Install new wiper motor assembly. In the new wiper motor system, the parameters for detecting dry conditions have been optimized.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11023025-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11023025-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11023025","components":[{"id":"visibility","name":"Glass, wipers and mirrors","parent":null},{"id":"wiper","name":"Wipers and washers","parent":"visibility"}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG GLA 35","year_from":2024,"year_to":2025,"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":2021,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLB35","year_from":2021,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLA 250","year_from":2020,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLA 250 4MATIC","year_from":2024,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLB 250","year_from":2020,"year_to":2025,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
