2026 TESLA MODEL Y — Complaint #2150771
Open-data reference.
NHTSA Complaint about LANE DEPARTURE: ASSIST filed November 21, 2025
NHTSA complaint #2150771 (ODI reference 11700778) concerns a 2026 TESLA MODEL Y and was filed on November 21, 2025. The owner reports the failure occurred on November 21, 2025. The report was geocoded to Pennsylvania 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 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 2026 TESLA MODEL Y shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
My car installed update v12 (2025.38.8.7) last night. This morning I was driving to work using autopilot when alarms sounded, the hazard lights turned on, and the screen flashed a warning that I had to take over immediately. The message included a note that autopilot had failed due to a "systems error." The navigation and visualization screen froze, went blank, and took 10 minutes to come back on. I asked Tesla to roll back the update and they have told me that they cannot do that. I came very close to crashing into a concrete guard rail as the car was going around a turn when the system failed.
