What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationMercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2023 EQS (296 platform) vehicles, limited or no customer-ready operating instructions and supplemental content were provided with the vehicle; furthermore, only a partially customer-ready Digital Owner's Manual was flashed on the head unit. As a result, customers may receive operating instructions that are not suitable for their market and/or are not in their language. Additionally, there may be missing function descriptions, and technical and safety information that are not user-friendly, which may lead to customer complaints. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealership will provide a hardcopy of the Owner’s manual update the Digital Owner's Manual.

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 Mercedes-Benz NCU-2023040015 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 NCU-2023040015 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. Every Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
Which vehicles does NCU-2023040015 cover?
The manufacturer filed it against 1 model year: 2023 Mercedes-Benz EQS. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
