2023 MERCEDES-BENZ EQB 300 4MATIC — Complaint #2146060
Open-data reference.
NHTSA Complaint about ELECTRICAL SYSTEM filed November 5, 2025
NHTSA complaint #2146060 (ODI reference 11697675) concerns a 2023 MERCEDES-BENZ EQB 300 4MATIC and was filed on November 5, 2025. The owner reports the failure occurred on October 20, 2025. The report was geocoded to California based on the filer's self-reported location. The affected component is categorized as electrical system, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same MERCEDES-BENZ EQB 300 4MATIC cohort independently describe similar electrical system failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2023 MERCEDES-BENZ EQB 300 4MATIC shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
In December 2024, I brought my 2023 Mercedes-Benz EQB to Mercedes-Benz Beverly Hills for scheduled service. They told me the vehicle had a recall and booked me for a future appointment, but I was unable to attend because I was out of town. I called the dealer multiple times afterwards to reschedule, but they never told me the reason for the recall or explained the safety risk. I recently checked my VIN myself and discovered that the recall is related to a high-voltage battery defect that may cause sudden loss of power and battery fire. I was never properly informed by Mercedes-Benz about this serious safety hazard. I rely on this vehicle to transport my two young children. This is an electric vehicle with a battery fire risk and possible loss of power at highway speeds. Mercedes-Benz has not provided a remedy, repair, loaner vehicle, or timeline. I am requesting NHTSA assistance to ensure Mercedes-Benz addresses this safety recall or provides a safe replacement or loaner vehicle unt
