This condition may result in a reduction of electrical isolation and a corresponding malfunction indicator on the driver display informing the driver that the vehicle requires service. In rare instances, the driver will receive a notification to pull over safely and the vehicle will enter a reduced performance safe-state mode. Rivian will inspect the south/rear multifunction module and replace the south/rear multifunction module or the HV battery energy management control module. Rivian is launching this campaign for customer satisfaction and to ensure the quality of Rivian vehicles.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11038239-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11038239-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11038239","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"RIVIAN","model":"R2","year_from":2027,"year_to":2027,"match":"exact","vehicle_ids":["2027_rivian_r2"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
