Rivian bulletin FSAM-1785
Rivian filed this with NHTSA as a service bulletin dated May 19, 2026, received Jun 4, 2026, about the electrical system — 1 document under this number: RSB-86-26-001-1. It names 6 model years (2022–2024). 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 launching a technical service bulletin for some model year 2022-2024 R1 vehicles that may have ultrasonic sensors detached from the front fascia mounting area. After detachment, the ultrasonic sensor may become dislodged and hang inside the front fascia, causing customer notifications for sensor issues and potential sensor damage. Upon ultrasonic sensor detachment, Rivian will perform an ultrasonic sensor repair to secure the sensor to the front fascia.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Rivian FSAM-1785 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 FSAM-1785 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 FSAM-1785 cover?
The manufacturer filed it against 6 model years: 2024 Rivian R1S, 2023 Rivian R1S, 2022 Rivian R1S, 2024 Rivian R1T, 2023 Rivian R1T, 2022 Rivian R1T. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
