PURPOSE: LiveWire EV, LLC has identified that certain S2 motorcycles do not recognize the full connectivity benefit due to the lack of completion of regularly scheduled Firmware Over The Air (FOTA) updates. Certain S2 motorcycle’s Telematic Control Unit (TCU) that have not been updated to the latest software version which prevents full operation of the TCU and the motorcycle’s ability to receive FOTA updates will need to be inspected and the TCU replaced. Vehicle performance and safety are not affected. Additionally, there is an upcoming cloud update scheduled for August 31st, 2025, which will prevent motorcycles with these early TCU software versions from connecting to cloud services. If the affected vehicle's TCU is not updated by this time, connected service within the LiveWire S2 mobile app will cease to function.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11016830-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11016830-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11016830","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"LIVEWIRE","model":"S2 DEL MAR","year_from":2024,"year_to":2024,"match":"exact","vehicle_ids":["2024_livewire_s2-del-mar"]},{"make":"LIVEWIRE","model":"S2 MULHOLLAND","year_from":2024,"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.
