Nissan filed this with NHTSA as a service bulletin dated Aug 15, 2024, received Sep 4, 2024, about the electrical system. It names 18 model years (2020–2024).

Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTELEMATICS CONTROL UNIT RESET AFTER AUTOMATIC COLLISION NOTIFICATION This bulletin has been amended. See AMENDMENT HISTORY on the last page. Please discard previous versions of this bulletin. SERVICE INFORMATION The Telematics Control Unit (TCU) has the ability to send an automatic collision notification when the vehicle is involved in an accident. Once an automatic collision notification is performed, the function becomes disabled and the TCU must be reset to re-enable the automatic collision notification function. Some models will store DTC B2E1B-97 for “Automatic eCAll locked” as “CURRENT” when this function is disabled. This bulletin describes how to reset the TCU after an automatic collision notification has been performed. For models with B2E1B-97 for “Automatic eCAll locked” set as “CURRENT”, complete the SERVICE PROCEDURE starting on page 2, and then erase DTCs after confirming the TCU condition is “UNLOCK”.

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 17 model years this bulletin names have filed 1,398 complaints with NHTSA since 2015. 159 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan NTB20-085C 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 NTB20-085C 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 NTB20-085C cover?
The manufacturer filed it against 18 model years: 2024 Nissan Armada, 2023 Nissan Armada, 2022 Nissan Armada, 2021 Nissan Armada, 2023 Nissan Frontier, 2022 Nissan Frontier and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
