2016 FIAT 500X — Complaint #2142877
Open-data reference.
NHTSA Complaint about FUEL SYSTEM, GASOLINE:STORAGE:EVAPORATIVE EMISSIONS:HOSES/VALVES/SENSORS filed October 24, 2025
NHTSA complaint #2142877 (ODI reference 11695494) concerns a 2016 FIAT 500X and was filed on October 24, 2025. The owner reports the failure occurred on March 24, 2025. The vehicle had 145,297 miles on the odometer at the time of the incident. The report was geocoded to Pennsylvania based on the filer's self-reported location. The affected component is categorized as fuel system, gasoline:storage:evaporative emissions:hoses/valves/sensors, 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 FIAT 500X cohort independently describe similar fuel system, gasoline:storage:evaporative emissions:hoses/valves/sensors 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 2016 FIAT 500X shows the complete component-level complaint distribution alongside any active investigations or recalls.
