NHTSA Complaint about ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY:MANAGEMENT SYSTEM/ENERGY CONTROL MODULE (BMS/BECM) filed April 28, 2022

NHTSA complaint #1809826 (ODI reference 11462618) concerns a 2021 FORD MUSTANG MACH E and was filed on April 28, 2022. The owner reports the failure occurred on October 29, 2021. The report was geocoded to Connecticut based on the filer's self-reported location. The affected component is categorized as electrical system:propulsion system:traction battery:management system/energy control module (bms/becm), 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 FORD MUSTANG MACH E cohort independently describe similar electrical system:propulsion system:traction battery:management system/energy control module (bms/becm) 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 2021 FORD MUSTANG MACH E shows the complete component-level complaint distribution alongside any active investigations or recalls.

Complaint Description

At around 600 miles my vehicle displayed "high voltage battery warning" and "powertrain malfunction" dashboard warning lights. Each light had an associated description that indicated the vehicle's power could fail at any time. This is a 1st model year all electric vehicle. The fact this occurred within 1k miles of ownership is concerning. I took it to a local Ford dealer, ultimately they replaced the high voltage battery junction box and battery electronic control module.
