What the bulletin says

Source: NHTSA's summary of the manufacturer's communication

Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2023 -2024 GLC (254 platform), C-Class (206 platform), CLE (236 platform), E-Class (214 platform) and S-Class (223 platform) vehicles, the 48-volt battery module (BMS) control unit software does not correspond to the current series production configuration. It is therefore possible that the battery's state of health is calculated incorrectly, thereby falsely illuminating check engine light ‘MIL’ (malfunction indicator lamp).

Read by machine from the document NHTSA serves (6 pages), read Sep 30, 2026. A part number is shown only where it matches Mercedes-Benz’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 database

Owners of the 6 model years this bulletin names have filed 135 complaints with NHTSA since 2015. 52 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.

This vehicle has now had three episodes where warning lights came on for no apparent reason. There have been two episodes of "Check Engine Light" coming on, the first with less than 1000 miles on the vehicle. It was driven to the dealer and they checked finding no problems and said not to worry about it.

2023 Mercedes-Benz GLC-Class · Electrical System · filed with NHTSA Jan 3, 2024 · ODI 11563288

The contact owns a 2024 Mercedes Benz E. The contact stated that while the vehicle was parked, and started, the instrument panel and infotainment screen became blank. No warning indicators or audible assistance and other vehicle assistance were not able to display due to the failure.

2024 Mercedes-Benz E-Class · Electrical System · filed with NHTSA Jun 2, 2026 · ODI 11741513

The control unit in my 2024 Mercedes 2580e triggers an increased number of system resets as part of fallback behavior. The increased number of resets resulted in the digital instrument cluster's display temporarily cutting out, and I had an entirely blank cluster.

2024 Mercedes-Benz S-Class · Electrical System · filed with NHTSA May 11, 2026 · ODI 11737040

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 2024020014 a recall?

No. A emissions communication 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 2024020014 repair free?

A emissions communication 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 2024020014 cover?

The manufacturer filed it against 6 model years: 2024 Mercedes-Benz C-Class, 2024 Mercedes-Benz CLE-Class, 2024 Mercedes-Benz E-Class, 2024 Mercedes-Benz GLC-Class, 2023 Mercedes-Benz GLC-Class, 2024 Mercedes-Benz S-Class. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
