In some instances, this condition may result in a loss of torque of the halfshaft bolt and subsequent noise and/or separation of the bolt and wheel center cap. Without this bolt there may be additional movement of the components and/or noise but there will be no resulting changes in the performance of the vehicle. Rivian will replace the halfshaft bolts and torque them to a higher specification to improve the press fit force and bolt retention. In addition, washers will be installed on the halfshafts to reduce potential noise. Rivian is launching this campaign for customer satisfaction and to ensure the quality of Rivian vehicles. Note: This document supersedes RCA-38-23-001-1. Revision 2 reduces the labor required to access the halfshafts.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10240309-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10240309-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10240309","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"RIVIAN","model":"R1S","year_from":2022,"year_to":2022,"match":"exact","vehicle_ids":["2022_rivian_r1s"]},{"make":"RIVIAN","model":"R1T","year_from":2022,"year_to":2022,"match":"exact","vehicle_ids":["2022_rivian_r1t"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
