The contact owns a 2012 Toyota Prius C. The contact stated that while driving 20 MPH, the message "Check Hybrid Status - Stop vehicle in Safe Place Immediately" was displayed. There were several warning lights illuminated. The vehicle was towed to the local dealer, where it was diagnosed with an internal power module transmitter and MG control computer inside the inverter assembly failures. The vehicle was not repaired. The contact called an independent mechanic, and DTC: P0A94 (DC/DC converter or inverter performance problem invertor assembly) was associated with the failure. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 98,015.

I am writing to express a complaint regarding the issues I have experienced with the brake system of my Toyota Prius C, 2012 model. For the past several months, I have noticed that the brakes exhibit strange noises, soft pedal sensation, reduced braking efficiency, were driving and the ABS, traction, brake, and that other light turned on and the brakes became slow these issues have been observed on multiple occasions and pose a safety risk to myself, other drivers, and pedestrians. I have taken the vehicle for inspection, but the problems persist or have not been definitively resolved. I believe these faults may be related to defects in the braking system, and therefore I request a thorough inspection and necessary repairs at no cost, considering that the manufacturer could be responsible for manufacturing defects.

I was driving on the expressway and experienced a sudden loss of power. The internal combustion engine suddenly stopped and did not deliver any power to the wheels. I immediately received a message on the system that said 'Check Hybrid System Stop Vehicle in a Safe Place'. The electric motor still continued to provide some power with the available battery charge. I was able to make it to the shoulder of the road but it was challenging to get to the shoulder with no power or warning and high speed traffic. My wife and I were in the vehicle. The vehicle had no engine or error codes until the failure on the expressway. The vehicle has the code P0A1A and P0A94. This is consistent with the error codes in the NHTSA 19V491000 recall and Toyota Safety Recalls E0E and F0R.

I was driving going 45mph when my car shut off and wouldn't start back up. It almost caused an accident from it stopping in the middle of the highway. The master warning light, brake system warning light, warning buzzer ABS warning light and the slip indicator light came on as also the message center reading to have the hybrid system checked immediately. I did have ot towed on for a diagnosis and it came back saying i needed a new inverter power module this will cost $2000 . i cant afford that. I read all over the internet how there is. Safety recalls. When i called toyota they said there are no recalls so now im stuck paying this. Not happy at all!!! If there are anymore 2012 prius with this problem please write a complaint so we can get this on recall and have the company cover the cost of repair.

I was driving with my 10 year old son on local city streets. I was approaching a busy intersection while going approximately 35 miles when my car just turned off with an error message about the hybrid system failing. I stopped the car and put it in park while trying to turn the car back on, but I kept getting the same hybrid system error message. While the stoplight was red, I got my son out of the car and over to the sidewalk because this was a dangerous situation where anyone not paying attention could've slammed into my stalled car (see picture of black Toyota Prius). I called AAA to get it towed. About 20 minutes later, a cop car pulled up to block my stalled car and then got it pushed to the side of the road (picture attached) because of how dangerous it was sitting there blocking traffic at a major intersection. My car was taken to Cabe Toyota dealership where they diagnosed it with a failed IPM card, which would cost around $4,000 to replace. I did a simple Google search and found that 80,000 Prius from 2012 - 2014 have been recalled for this EXACT reason. There have also been class action lawsuits surrounding this IPM failure due to its extreme safety risks to anyone inside a car that will just die in the middle of driving it, especially when their fail-safe system does not get triggered with this particular IPM failure. As of right now, the car is available for inspection because it's still at Cabe Toyota. The invoice shows that the IPM card needs to be replaced. There were NOT any warning lamps, messages, or other symptoms prior to the car shutting off while driving it. It had been running just fine.

DP22005 · Pedestrian Alert Sounds

Opened Jan 27, 2023 · Closed Aug 7, 2023

Status: closed (inferred from source dates) · Electrical System:propulsion System

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

DP13002 · Drivability, Service Brake Failure

Opened Mar 18, 2013 · Closed Jul 25, 2014

Status: closed (inferred from source dates) · Service Brakes

On January 3, 2013, NHTSA received a letter (ODI No. 10487746) from Ms. Jessie A. Powell petitioning the agency to investigate drivability and braking concerns in the subject vehicle.The petition expressed two concerns: 1. The first software problem was when the vehicle shifted from battery to motor and caused such impact, I initially believed the vehicle had been struck in the rear.2. The next more alarming problem was NO BRAKES. The brake pedal traveled to the floor and a dashboard warning light flashed.This symptom occurred twice, leading to the vehicle being towed to the dealership, the second time in the dealership parking lot after diagnostics of the first incident.After a test drive and vehicle inspection, no actionable problem was found within the petitioner?s vehicle.The braking concern reported turned out to be normal vehicle operation.The petitioner identified other complaints of poor braking performance and low brake pedal received by NHTSA concerning Prius models. Broader review of the consumer complaints reported for all variants of the subject vehicle showed no indication that either the reported jolting sensation or the brake performance concerns reported are occurring in this vehicle population at a level that would require investigative action by NHTSA.The following recalls by Toyota were to address many of these complaints in Prius variants. Neither of these recalls is applicable to Ms. Powell?s 2012 Prius C: 1. Recall 10V-039 March 5, 2010 - 2010 Prius, Lexus HS - Reprogramming ABS ECU - Improve Antilock brake function over bumpy surfaces. 2. Recall 13V-235 August 7, 2013 - 2010 Prius, Lexus HS - Replace Brake Booster / Pump assembly - Low brake pedal due to nitrogen bubble in hydraulic portion of brake system. In the Agency?s view, additional investigation is unlikely to result in a finding that a defect related to motor vehicle safety exists in the subject vehicles.Therefore, given the need to allocate and prioritize NHTSA limited resources to best accomplish the Agency?s safety mission, the petition is denied.This action does not constitute a finding by NHTSA that a safety-related defect does not exist.The Agency will take further action if warranted by future circumstances.More details concerning our review can be found in the Federal Register Notice for this action.
