What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationIMPORTANT INFROMATION Your vehicle has an OPEN safety recall regarding the high-voltage battery. The vehicle’s high voltage battery might be insufficiently robust at a high State of Charge (“SOC”) - an internal short circuit of a battery cell in the high-voltage battery might occur, which could lead to the risk of a fire, within the high voltage battery. Until the remedy software update is performed on your vehicle, the maximum SOC for your vehicle’s high-voltage battery must be set to 80%.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz CL-2025040005 a recall?
No. A manufacturer 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 CL-2025040005 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 CL-2025040005 cover?
The manufacturer filed it against 1 model year: 2023 Mercedes-Benz EQB. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
