2026 TESLA MODEL Y — Complaint #2178666
Open-data reference.
NHTSA Complaint about LANE DEPARTURE: WARNING filed February 19, 2026
NHTSA complaint #2178666 (ODI reference 11719201) concerns a 2026 TESLA MODEL Y and was filed on February 19, 2026. The owner reports the failure occurred on February 6, 2026. The report was geocoded to Massachusetts 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 2026 TESLA MODEL Y shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
I am submitting this complaint regarding a newly leased 2026 Tesla Model Y Premium RWD, which I took delivery of on February 6, 2026 from Tesla Watertown, MA. I am a returning Tesla customer and entered this lease after test driving the same model on January 24, which did not exhibit any issues. Immediately upon driving the vehicle off the lot (approximately 12 miles), I noticed a persistent rattling noise from the front suspension area. The noise occurs over normal road conditions and has been present since delivery, significantly affecting the quality and value of the vehicle. On February 9, Tesla Watertown evaluated the vehicle and later replaced both front upper control arm (FUCA) mounts. On February 10, before repairs were completed, multiple safety systems suddenly disabled while driving, including regenerative braking behavior, traction and stability control, lane safety features, and automatic emergency braking, creating a dangerous situation. I returned the vehicle immediately
