2014 TOYOTA PRIUS — Complaint #2119667
Open-data reference.
NHTSA Complaint about TRACTION CONTROL SYSTEM filed August 12, 2025
NHTSA complaint #2119667 (ODI reference 11680048) concerns a 2014 TOYOTA PRIUS and was filed on August 12, 2025. The owner reports the failure occurred on March 12, 2025. The vehicle had 150,000 miles on the odometer at the time of the incident. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as traction control system, 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 traction control system 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 2014 TOYOTA PRIUS shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2014 Toyota Prius. The contact stated that the ABS and the traction control warning lights were illuminated. The vehicle was taken to the dealer to be diagnosed, and the contact was informed that the brake master cylinder needed to be replaced. The vehicle was not repaired. The vehicle was taken to a certified mechanic and was diagnosed, and it was determined that the brake booster had failed and needed to be replaced. The vehicle was repaired; however, one day later, both warning lights returned. The vehicle was returned to the mechanic and air was blown into the hydraulic valves and the other valves were cleaned; however, the failure persisted. The manufacturer was not informed of the failure. The failure mileage was approximately 150,000.
