Open-data reference.
NHTSA Complaint about ELECTRICAL SYSTEM:INSTRUMENT PANEL:SPEEDOMETER/ODOMETER:SENSOR/SENDING UNIT filed January 5, 2024
NHTSA complaint #1955483 (ODI reference 11563672) concerns a 2021 FORD MUSTANG MACH E and was filed on January 5, 2024. The owner reports the failure occurred on January 4, 2024. The report was geocoded to California based on the filer's self-reported location. The affected component is categorized as electrical system:instrument panel:speedometer/odometer:sensor/sending unit, 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:instrument panel:speedometer/odometer:sensor/sending unit 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.

In essence, I couldnât tell how fast I was going. After closer examination (mind you I was driving while figuring this stuff out), I noticed that the instrument cluster would update once in say 10seconds or so (but it was variable). I tried to set cruise control to initiate blue cruise, but I couldnât tell what speed cruise control was being set to due to this enormous lag. I also wasnât sure if the system would also exhibit this lag. Finally, I noticed that even the lights indicator for t
