2026 TESLA MODEL Y — Complaint #2140300
Open-data reference.
NHTSA Complaint about ELECTRICAL SYSTEM:ADAS:AUTONOMOUS/SELF DRIVING filed October 16, 2025
NHTSA complaint #2140300 (ODI reference 11693777) concerns a 2026 TESLA MODEL Y and was filed on October 16, 2025. The owner reports the failure occurred on September 29, 2025. The vehicle had 400 miles on the odometer at the time of the incident. The report was geocoded to Illinois based on the filer's self-reported location. The affected component is categorized as electrical system:adas:autonomous/self driving, 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 electrical system:adas:autonomous/self driving 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
The contact owns a 2026 Tesla Model Y. The contact stated that while driving at various speeds in Autopilot Mode, the vehicle misread nearby road signs.

While driving on a road with a slight ramp with the Speed Limit of 40 MPH or 45 MPH, once the vehicle was on the ramp, the vehicle unintendedly accelerated to approximately 50 - 55 MPH. There were no warning lights illuminated during the failures. The contact stated that the vehicle failed to exceed 40 - 45 MPH while driving on other roadways. The vehicle failed to maintain the desired speed during each failure without a warning light being illuminated. The dealer was contacted, and the vehicle was taken to the dealer, but the vehicle was not yet diagnosed or repaired. The manufacturer was informed o
