Mercedes-Benz bulletin 2024120010

What it saysMercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2024 EQB (243 platform) vehicles, the BMS software does not correspond with current production specifications. NHTSA’s full summary ↓

Mercedes-Benz filed this with NHTSA as a service bulletin dated Jan 10, 2025, about the electrical system. It names 1 model year (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.

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 database

Owners of the 1 model year this bulletin names have filed 14 complaints with NHTSA since 2015. 9 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.

I am currently leasing a 2024 Mercedes-Benz EQB 250+. The vehicle displayed a warning related to the high-voltage battery system, indicating a potential malfunction and safety risk. I was advised that there may be an issue involving the high-voltage battery that could lead to battery failure and/or an increased risk of fire.

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 579.5

Is Mercedes-Benz 2024120010 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 2024120010 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 2024120010 cover?

The manufacturer filed it against 1 model year: 2024 Mercedes-Benz EQB. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
