2025 SUBARU OUTBACK — Complaint #2138394
Open-data reference.
NHTSA Complaint about LANE DEPARTURE: ASSIST filed October 11, 2025
NHTSA complaint #2138394 (ODI reference 11692655) concerns a 2025 SUBARU OUTBACK and was filed on October 11, 2025. The owner reports the failure occurred on August 1, 2025. The report was geocoded to California based on the filer's self-reported location. The affected component is categorized as lane departure: assist, 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: assist 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 2025 SUBARU OUTBACK shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
Since October 2023, my 2019 Toyota Prius has developed severe and unpredictable driving behavior after a regular brake service, which may have triggered or coincided with a software or ECU update. The car, which had been driving smoothly since I bought it in 2021, suddenly began showing false braking, steering interference, and lane instability â as if the car were trying to âcorrectâ problems that didnât exist. These interventions often happen on highways or during turns, creating serious safety risks for both driver and passengers. Iâve spent months and thousands of dollars replacing parts, performing alignments, and recalibrating sensors, including at Toyota dealerships. The problem persists because it is software-based, not mechanical. I discovered that in midâ2023, the NHTSA announced upcoming rules requiring Automatic Emergency Braking (AEB) with pedestrian detection by 2029. Around that same time, reports from multiple drivers (Toyota, Honda, Hyundai, Ford, Subaru)
