Mercedes-Benz EQB battery fires and AMG wiring shorts: what owners face
⚠ 4 carry a park-outside (fire risk) advisory.
Twenty-two electrical recalls, and the loudest theme is the EQB high-voltage battery: four campaigns between 2025 and 2026 cover 2022-2024 EQB 250, EQB 250+, EQB 300 4MATIC and EQB 350 4MATIC for internal battery failure that can start a fire parked or driving, with some cars already repaired under 25V050 needing the work again. A fifth EQB recall blames wrong bus bar screws for sudden loss of drive power, and EQE/EQS models share a battery management software power-loss recall. The second cluster is AMG E53, CLS53, GT43 and GT53 wiring — a misrouted transmission harness that can corrode and short, and a loose 48-volt ground cable that can overheat. Sprinter and Metris vans add a missing battery cover, swivel-seat wiring, park-lock rollaway and eCall location faults.
Warning signs to watch for
- A burning smell, smoke or any electrical malfunction — the AMG transmission harness notice asks owners to report these immediately
- Sudden loss of drive power with no warning while moving, on EQB, EQE and EQS models
- The instrument panel display going blank while driving on 2024-2026 C-Class, E-Class, CLE, GLC, SL and AMG GT vehicles
- Loss of anti-lock brakes and electronic stability control on 2019-2021 G550 and AMG G63
- A Sprinter that moves after the gear selector is placed in Park without the parking brake applied
Is it safe to keep driving?
No recall here tells you to stop driving. Four EQB battery campaigns do add conditions: park outside and away from structures, and charge to no more than 80 percent until the update is installed. The EQB bus bar recall also says park outside while the phased remedy rolls out. Everything else — AMG wiring, the 48-volt ground cable, EQE/EQS power loss, G-Class harness chafing, the blank instrument display and the Sprinter park-lock software — is driveable, but fire and sudden-power-loss risks make these soon repairs, and always set the parking brake on affected Sprinters.
What the free repair involves
The work splits three ways. Software updates cover the battery management system, ESP control unit, infotainment unit and eCall communication module. Inspection-and-repair covers the 48-volt ground cable connection, transmission harness connectors, and the front axle harness, which gets a protective sleeve or full replacement. Replacement covers the two-part AMG harness and connector, Metris battery compartment covers, and high-voltage batteries where needed. All free of charge.

Common questions
My EQB already had its battery recall done — am I finished?
Not necessarily. The December 2025 campaign states that vehicles previously repaired under recall 25V050 need to be repaired again. Until that update is complete, Mercedes advises parking outside and charging to a maximum of 80 percent battery capacity.
Why does Mercedes say park outside but not stop driving my EQB?
The notices describe a high-voltage battery that may fail internally and cause a fire while parked or driving. Rather than a stop-driving order, Mercedes issued parking and charging limits: park outside, away from structures, and charge to no more than 80 percent.
The AMG harness repair isn't available yet — what should I do meanwhile?
The June 2024 recall sent interim letters about the safety risk and says a second notice follows once the final remedy, replacing the two-part wiring harness and connector, is ready. Until then, report any burning smell or electrical problem right away.
