2021 SUBARU OUTBACK — Complaint #2113457
Open-data reference.
NHTSA Complaint about LANE DEPARTURE: SENSING SYSTEM: RADAR filed July 24, 2025
NHTSA complaint #2113457 (ODI reference 11675847) concerns a 2021 SUBARU OUTBACK and was filed on July 24, 2025. The owner reports the failure occurred on July 11, 2025. The vehicle had 18,640 miles on the odometer at the time of the incident. The report was geocoded to South Carolina based on the filer's self-reported location. The affected component is categorized as lane departure: sensing system: radar, 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 SUBARU OUTBACK cohort independently describe similar lane departure: sensing system: radar 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 SUBARU OUTBACK shows the complete component-level complaint distribution alongside any active investigations or recalls.
