RCA-38-23-002-2: Install Halfshaft Washers
Rivian is initiating a customer satisfaction campaign for some model year 2022 R1T and R1S vehicles that may
have been built with excessive clearance space between the halfshafts and wheel hubs. In some instances, this
may result in a brief noise coming from the front and/or rear of the vehicle when accelerating or decelerating
that is noticeable to the customer but would not result in any changes in the performance of the vehicle. Rivian
will install washers on both the front and rear halfshafts to remove the excess clearance and eliminate the
noise. Rivian is launching this campaign for customer satisfaction and to ensure the quality of Rivian vehicles.
Note: This document supersedes RCA-38-23-002-1. Revision 2 reduces the labor required to access
the halfshafts.
