2011 TOYOTA PRIUS — Complaint #1842474
Open-data reference.
NHTSA Complaint about EQUIPMENT ADAPTIVE/MOBILITY:VEHICLE CONTROLS:SPEED CONTROL filed September 21, 2022
NHTSA complaint #1842474 (ODI reference 11485677) concerns a 2011 TOYOTA PRIUS and was filed on September 21, 2022. The owner reports the failure occurred on August 25, 2022. The vehicle had 3,000 miles on the odometer at the time of the incident. The report was geocoded to Wisconsin based on the filer's self-reported location. The affected component is categorized as equipment adaptive/mobility:vehicle controls:speed control, 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: yes, fire: no, injuries: 0, fatalities: 0. A complaint that flags a crash, fire, or fatality is escalated on NHTSA's internal review queue and factors more heavily into any Preliminary Evaluation decision on this make and model. 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 equipment adaptive/mobility:vehicle controls:speed control 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 2011 TOYOTA PRIUS shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owned a 2011 Toyota Prius. The contact stated while driving 30 MPH, the vehicle accelerated at uncontrollable speed, and an unknown warning light illuminated. The contact depressed the brake pedal desperately and the vehicle would not stop. The contact swerved into the lane of the opposite direction causing the contact to strike the front passenger end of the vehicle traveling in the opposite direction, causing the other vehicle to drive into the woods, and the contact vehicle spun in a circle. The contact stated he pulled the emergency brake causing the vehicle to come to a complete stop. No air bags deployed. No one was injured but the contact was unaware if there were any injuries to the other driver. A police report was filed. The vehicle was towed from the scene and later deemed a total loss. The manufacturer was contacted, and they stated that the accident was being investigated. The failure mileage was 3,000.
