Mercedes-Benz bulletin LI54.10-P-080684
Mercedes-Benz filed this with NHTSA as a service bulletin dated Aug 6, 2026, received Aug 11, 2026, about the electrical system. It names 1 model year (2026). 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint When disconnecting or connecting the charging connector, the charging socket flashes red and red warning messages are displayed in the instrument cluster. Immediately after that, neither driving nor charging is possible. Cause P292900: If the charging cable connector is removed approximately 5 to 7 seconds after the charging process has ended, a fault is triggered. Remedy If this fault occurs, please follow these steps: 1) Wait for bus idle -> driving should be possible again. Note: Charging is still not possible. The fault will keep recurring as long as the fault is stored in the fault memory. 2) Plug in charging cable and check if fault (P292900 or P0AE173) is active. Clear active fault. Charging should be possible after the fault has been cleared. To prevent the fault from recurring, after the charging process has ended, wait at least 15 seconds before disconnecting the AC charging cable connector. Please create a TIPS case including quick test and HV control module log.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI54.10-P-080684 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 LI54.10-P-080684 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 LI54.10-P-080684 cover?
The manufacturer filed it against 1 model year: 2026 Mercedes-Benz G-Class. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
