Open-data reference.
NHTSA Complaint about FUEL SYSTEM, GASOLINE:STORAGE:EVAPORATIVE EMISSIONS:CANISTER filed August 15, 2025
NHTSA complaint #2120983 (ODI reference 11680950) concerns a 2004 LAND ROVER DISCOVERY and was filed on August 15, 2025. The owner reports the failure occurred on August 8, 2025. The vehicle had 106,683 miles on the odometer at the time of the incident. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as fuel system, gasoline:storage:evaporative emissions:canister, 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 LAND ROVER DISCOVERY cohort independently describe similar fuel system, gasoline:storage:evaporative emissions:canister failures, defect investigators have grounds to open a PE and request manufacturer data.
