Rivian filed this with NHTSA as a service bulletin dated Jul 19, 2023, received Aug 3, 2023, about the power train. It names 2 model years (2022). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationRivian is initiating a customer satisfaction campaign for some model year 2022 R1S and R1T vehicles that may have been built with inadequate press fit force between the halfshaft splines and the wheel hubs. 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 79 complaints with NHTSA since 2015. 8 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Rivian RCA-38-23-001-2 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the RCA-38-23-001-2 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does RCA-38-23-001-2 cover?
The manufacturer filed it against 2 model years: 2022 Rivian R1S, 2022 Rivian R1T. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
