2007 TOYOTA PRIUS — Complaint #1900100
Open-data reference.
NHTSA Complaint about ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY filed June 6, 2023
NHTSA complaint #1900100 (ODI reference 11525645) concerns a 2007 TOYOTA PRIUS and was filed on June 6, 2023. The owner reports the failure occurred on May 30, 2023. The vehicle had 160,000 miles on the odometer at the time of the incident. The report was geocoded to District of Columbia based on the filer's self-reported location. The affected component is categorized as electrical system:propulsion system:traction battery, 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 electrical system:propulsion system:traction battery 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 2007 TOYOTA PRIUS shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2007 Toyota Prius. The contact stated that while at a stop light, she attempted to drive however, the vehicle failed to exceed 25 MPH. The HC battery, ECU, and check engine warning lights were illuminated. The vehicle was towed to an independent mechanic, who informed the contact that the vehicle displayed DTC code: P3190 (Engine Failure). The vehicle was towed to the local dealer, where it was diagnosed that the hybrid battery was severely drained, and the mechanic retrieved DTC codes: P3000 and P0A80 for the hybrid battery pack. The vehicle was not repaired. The vehicle was towed to another independent mechanic, who replaced the battery, but the failure persisted. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 160,000. The contact stated the vehicle was actually overfilled with oil at the mechanic's shop that performed the oil change, so that is what caused the issues with my vehicle.
