Due to the physical connection of the HV refrigerant compressor to the HV electrical system, the insulation error would trigger a fault in the entire HV electrical system. A warning message may be displayed (e.g., battery symbol with text malfunction, without restarting engine - visit workshop, towing prohibited see owner's manual) in the instrument cluster. Both electric and combustion engine driving is possible. However, if the driver ignores the visit workshop without restarting a message and switches off the vehicle, it would no longer be able to start.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10253707-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10253707-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10253707","components":[{"id":"visibility","name":"Glass, wipers and mirrors","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"C 350 E","year_from":2018,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"C350E","year_from":2016,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC 350 E","year_from":2018,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC 350 E","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC350E","year_from":2019,"year_to":2019,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLE 550 E","year_from":2018,"year_to":2018,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLE550E","year_from":2016,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"S 560 E","year_from":2019,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"S550E","year_from":2017,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"redundant S550E","year_from":2015,"year_to":2015,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
