2023 Mercedes-Benz EQB 250+ electrical problems

Filed Oct 15, 2026 · Brakes, Driver assistance · FL

My 2023 Mercedes-Benz EQB250 (VIN: [XXX]) is currently sidelined at Mercedes-Benz of Pompano with a dangerous High-Voltage system failure that causes an immediate cascade error of the Electronic Stability Program (ESP) and vehicle braking systems. The technician verified the codes match Mercedes Service Bulletin LI42.45-P-079407 for an HV DC/DC Converter defect and matched my serial number to the bad batch. The vehicle simultaneously carries an active Federal Safety Recall for an internal High-Voltage Battery Pack explosion/fire risk (the federal safety agency Campaign 26V073). Mercedes-Benz USA Corporate (Case #[XXX]) and Service Director Hayden Smith are actively refusing to honor the 8-year/100,000-mile High-Voltage warranty on this converter. Furthermore, the dealership is threatening to charge me 'late fees' to strip away alternative loaner transportation. They are actively attempting to force a consumer to either pay $5,800 out-of-pocket for a warrantied high-voltage component or drive a compromised EV powertrain that violates the manufacturer's own outdoor parking safety mandates, as the owner resides in an apartment complex with an enclosed underground garage.

I am the owner/lessee of a 2023 Mercedes-Benz EQB 250+ (VIN: [XXX] ) affected by the federal safety agency safety recall 26V073 — a high-voltage battery fire risk defect that has failed three separate repair attempts. I am filing this complaint to document Mercedes-Benz USA’s failure to provide an adequate remedy under federal recall regulations. Background: Recall 26V073 was issued three separate times — first as recall 25V050 then 25V894 and finally 26V073. Each prior software remedy failed to resolve the underlying battery defect. Mercedes-Benz has now determined a full battery replacement is required. As of today no replacement battery is available for my specific vehicle VIN [XXX] . Current Situation: As a result of this unresolved recall I have been required to: • Park my vehicle outside and away from structures at all times • Restrict charging to a maximum of 80% capacity • Operate a fire risk vehicle for several months with no remedy available • Absorb $3,000 in home EV charger installation costs now largely unusable due to charging restrictions • Continue paying $22,000 in remaining lease obligations on a vehicle I cannot safely use Federal Compliance Failure: Under 49 CFR 573 Mercedes-Benz USA is required to provide affected owners with a free remedy within a reasonable timeframe. Mercedes-Benz USA has: • Failed to provide a repair — no remedy currently available • Formally declined to repurchase the vehicle • Offered $8,000 in goodwill compensation which does not constitute a remedy under federal recall regulations • Instructed my dealer Crown Eurocars in Pinellas Park Florida not to provide a loaner vehicle or storage assistance despite promising both in a written offer dated April 20 2026 Additional Bad Faith: Mercedes-Benz USA communicated a false claim to MBFS executive resolution team member Caroline stating that I had requested no further contact. I never made this request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
