2025 TESLA MODEL Y — Complaint #2178281
Open-data reference.
NHTSA Complaint about LANE DEPARTURE: ASSIST filed February 18, 2026
NHTSA complaint #2178281 (ODI reference 11718949) concerns a 2025 TESLA MODEL Y and was filed on February 18, 2026. The owner reports the failure occurred on January 28, 2026. 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: yes, fire: no, injuries: 2, fatalities: 0. A complaint that flags a crash, fire, or fatality is escalated on NHTSA's internal review queue and factors more heavily into any Preliminary Evaluation decision on this make and model. 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 TESLA MODEL Y 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 TESLA MODEL Y shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
On January 28, 2026, the vehicle (a Tesla Model Y) was operating with the Full Self-Driving (FSD) system actively engaged in normal highway traffic conditions. Without any prior warning messages, chimes, or system alerts, the FSD system abruptly disengaged approximately 1 second before the vehicle steered into a concrete road divider. Component failed: The Tesla Full Self-Driving (FSD) software and underlying perception/control systems failed to maintain the lane and abruptly handed over control with insufficient time to react. The vehicle and its data are available for inspection. Safety risk: The sudden, sub-second disengagement provided the driver with zero time to react, take manual control, or perform an evasive maneuver. This system failure directly resulted in a high-speed collision with a road divider, causing significant vehicle damage and physical injuries to the driver that required medical treatment. Inspection/Confirmation: The vehicle is currently subject to an open in
