It names 2 model years (2023–2024).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationRivian is initiating a customer satisfaction campaign for some model year 2023-2024 R1T vehicles that were built with a rear zone control module that could potentially be exposed to moisture. Over time, extended exposure could cause corrosion at the electrical connections. Rivian will install a water shield over the rear zone control module to prevent moisture exposure to the electrical connections. Rivian is launching this campaign for customer satisfaction and to ensure the quality of Rivian vehicles.

Read by machine from the document NHTSA serves (6 pages), read Sep 30, 2026. A part number is shown only where it matches Rivian’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 51 complaints with NHTSA since 2015. 10 of them name Electrical System — 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.
Following an over-the-air software update to the infotainment system (2026.31), Rivian replaced the persistent exterior ambient air temperature display on the primary screen with an internet-dependent third-party weather forecast feed.

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 FSAM-1755 a recall?
No. A service campaign 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-1755 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does FSAM-1755 cover?
The manufacturer filed it against 2 model years: 2024 Rivian R1T, 2023 Rivian R1T. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
