2015 TOYOTA PRIUS — Complaint #2178531
Open-data reference.
NHTSA Complaint about SERVICE BRAKES filed February 19, 2026
NHTSA complaint #2178531 (ODI reference 11719106) concerns a 2015 TOYOTA PRIUS and was filed on February 19, 2026. The owner reports the failure occurred on February 3, 2026. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as service brakes, 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 TOYOTA PRIUS cohort independently describe similar service brakes 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 2015 TOYOTA PRIUS shows the complete component-level complaint distribution alongside any active investigations or recalls.

I was advised the warranty for my vehicle expired 10/26/2025 (3 months and 8 days prior) and was now invalid. Brake replacement cost is $3675.00 + taxð¥´. I was provided warranty information and instructed to call Toyota. I called, spoke with Brook and was advised the warranty was invalid due to date even though the car has less than the 150, 000 mile covered and nothing could be
