“My 2022 Mercedes-Benz EQB 350 4MATIC (VIN [XXX]) is subject to NHTSA Recall 26V073 / MBUSA campaign 2026020004 for a high-voltage battery defect that may cause a thermal event/fire while parked or driving. Mercedes-Benz has determined that the permanent remedy requires replacement of the high-voltage battery, but MBUSA has confirmed that a replacement battery is not currently available for my VIN and has provided no firm repair date. Pending repair, Mercedes instructs owners to limit charging to 80% and park outside rather than in a garage or enclosed structure. These restrictions materially impair normal use. My wife's work requires frequent travel between [XXX] and [XXX], plus secure indoor garage parking at federal government facilities.

Despite 11 total service visits and 8 specific attempts to repair the battery management system and powertrain modules, the defect remains unresolved. The vehicle currently displays sudden red dashboard warnings stating "Engine will not restart" and "Malfunction" while driving at highway speeds and on sideroads. These incidents cause a sudden loss of confidence in the vehicle's propulsion and power. According to the manufacturer’s recall chronology, these warnings indicate a potential internal battery short circuit, which could lead to a thermal event/fire. Safety is compromised as the vehicle may stall in high-speed traffic, and the manufacturer has directed that the vehicle be parked outside and away from structures due to fire risk. The manufacturer has admitted that previous software "remedies" were failed attempts and that a hardware remedy (battery replacement) is unavailable for at least 9 months (December 2026) . This leaves the driver (owner) in a dangerous,…”
