2021 TESLA MODEL Y — Complaint #2139301
Open-data reference.
NHTSA Complaint about LANE DEPARTURE: WARNING filed October 13, 2025
NHTSA complaint #2139301 (ODI reference 11693127) concerns a 2021 TESLA MODEL Y and was filed on October 13, 2025. The owner reports the failure occurred on October 1, 2025. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as lane departure: warning, 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: warning 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 TESLA MODEL Y shows the complete component-level complaint distribution alongside any active investigations or recalls.

I as able to get off at the [XXX] exit for it is a bit of a "hill" up in Florida, but knew I could coast into a lane hopefully no one would be in. I was able to at least coast into a parking lot, and bump the car into a concrete barrier, and a tree infront of the barrier. The car would not respond to park, neutral or the emergency brake. I tried re-booting the car 3 times and nothing. I had to call a tow truck to tow to the Tesla Service Center in Cl
