Vehicle: 2005 Toyota Prius VIN: [XXX] Date of Incident: April 2024 Location: Citrus Heights, California Incident Summary: In April 2024, I was involved in a front-end collision while driving my 2005 Toyota Prius. I rear-ended another vehicle at moderate to high speed. Despite the severity of the impact, the driver-side airbag failed to deploy. As a result, I was thrown forward and hit my head on the windshield, suffering lacerations and head trauma. After being evaluated by emergency responders and undergoing a hospital visit (MRI included), I was told I had not sustained any life-threatening injuries. However, since the crash, I have experienced severe cognitive symptoms, including confusion, chronic fatigue, sudden drowsiness, memory loss, and extreme mood swings. These symptoms are ongoing and have made daily life extremely difficult. I had brought the vehicle to Roseville Toyota in Roseville, CA, for a full pre-purchase inspection prior to the crash. They provided a CARFAX vehicle history report, but they did not inform me that the airbag had failed to deploy in a previous incident listed in the report. I was unaware the airbag system might be defective, and if I had known, I would not have driven or purchased the vehicle. To this day, there has been no recall issued for airbags on this vehicle, and I believe this is a dangerous and potentially fatal defect that must be investigated by NHTSA. I am asking for an investigation into why the airbag system failed, and whether other Toyota Prius models from these years have similar undisclosed issues. Supporting Info: •The vehicle had dealership service history. •Toyota has documentation showing the vehicle was inspected and that I received the CARFAX, but they failed to alert me to the airbag defect. •I was paid out for the vehicle’s value and partial medical expenses through insurance, but no accountability has been taken for the **failed airbag INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

i had brake warning lights pop up on my dash..my brake actuator fail on my 05 prius.. this is a known issue with toyota prius. the brake actuator is a very important part of the braking system and vehicle is deemed unsafe with a failed actuator/module.. the dealer quoted over 3000 in repairs.. they were covering them for a while and now they are not.. the cost of the repair exceeds the value of vehicle due to the brake actuator being very expensive.. this is something that should have been recalled..
Brake actuator going bad. Safety is put at risk as brakes are slow to work and sometimes don't work at all for a couple of seconds, making sudden stops impossible. Has not been confirmed by dealer. Has not been inspected. ABS and TPMS light would briefly pop up for a couple of seconds on car startup before shutting off.

The Office of Defects Investigation (ODI) received a January 2013 defect petition requesting that it open an investigation on Model Year (MY) 2004-2009 Toyota Prius vehicles to address a possible manufacturing safety defect related to the steering column intermediate shaft.During the defect petition evaluation, ODI: 1.Reviewed the petition and its enclosures; 2.Reviewed the subject steering system layout; 3.Examined the Petition Vehicle?s history, including its repair history; 4.Reviewed and followed-up potentially related consumer complaints; 5.Assessed Safety Recalls 06V-188 and 12V-537; and, 6.Requested and examined complaint, claim, field report, service history, and warranty information from Toyota.ODI's review revealed that the petition vehicle had been recalled (Recall 06V188) to remedy a defect in the system identified in the petition with the remedy taking place prior to the failure that prompted the petition. Circumstances point to incorrect reassembly of the petitioner's vehicle by those who performed the recall remedy.ODI examined the issues raised by this petition to identify any related safety defect trend in the general subject vehicle population.That review identified a low rate of related consumer complaints (twenty-five over a eight year period from a population of over 600,000 vehicles) and no pattern that would identify either a safety defect not already covered by the two existing steering safety recalls by Toyota or a systematic problem with either recall remedy.Based on this evaluation, ODI does not believe that additional investigation will lead to a finding that a defect related to motor vehicle safety exists in the subject vehicles. Therefore, in view of the need to allocate and prioritize NHTSA?s limited resources to best accomplish the agency's safety mission, the petition is denied. The denial of this petition does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take further action if warranted by the circumstances.For more information, see the Federal Register notice in the public file for this action (https://www.nhtsa.gov/recalls#vehicle, select NHTSA ID, enter: DP13001)The ODI reports cited above can be reviewed on-line (https://www.nhtsa.gov/recalls#vehicle) under the following NHTSA ID numbers:10407520, 10418710, 10429551, 10473654, 10478195, 10478053, 10437229, 10489425, 10510722, 10639984, 10648277, 10499778, 10712626, 10723196, 10787530, 10808124, 10838803, 11071646, 11098144, 11099507, 11102659, 11160767, 11192607, 11287550, 11287606

ODI OPENED PE05-029 BASED ON 33 REPORTS OF ALLEGED GASOLINE ENGINE STALLING ON THE SUBJECT VEHICLES.THE SUBJECT VEHICLES ARE GASOLINE/ ELECTRIC HYBRID VEHICLES THAT CAN BE OPERATED IN GASOLINE OR ELECTRIC MODES, OR A COMBINATION OF BOTH DEPENDING ON THE POWER DEMAND.ALL REPORTS ALLEGE THAT THE GASOLINE ENGINE SHUT DOWN SUDDENLY WITHOUT WARNING.SOME OF THE COMPLAINANTS REPORTED THAT THE VEHICLE CONTINUED TO OPERATE USING THE ELECTRIC MODE FOR A PERIOD OF TIME AFTER THE GAS ENGINE STALLED AND SOME REPORTED THAT THE VEHICLE SHUT DOWN AT THE SAME TIME THAT THEY FELT THE GAS ENGINE STALLED.SOME CONSUMERS REPORTED THAT THEY WERE ABLE TO RESTART THE VEHICLE EITHER IMMEDIATELY OR AFTER ALLOWING THE VEHICLE SIT FOR A SHORT TIME, WHEREAS OTHERS REPORTED THAT THEY HAD THEIR VEHICLE TOWED.DURING PE05-029, ADDITIONAL FAILURE DATA WAS IDENTIFIED AS NOTED IN THE FAILURE REPORT SUMMARY ABOVE.THE COMPLAINT DATA REPRESENTS INCIDENTS WHERE ENGINE STALLING WAS ALLEGED OR WHERE THE VEHICLE WAS ALLEGED TO HAVE ONE OF THE VARIOUS CONDITIONS THAT CAUSES THE GAS ENGINE TO STALL.IN ITS AUGUST 26, 2005 RESPONSE TO ODI'S INFORMATION REQUEST, TOYOTA IDENTIFIED VARIOUS CONDITIONS THAT COULD CAUSE THE SUBJECT VEHICLES TO EXPERIENCE A GAS ENGINE STALL.IF THIS HAPPENS, THE DRIVER IS ALERTED BY AN AUDIBLE SOUND AND VARIOUS WARNING LIGHTS.THE VEHICLE WILL CONTINUE TO OPERATE IN THE ELECTRIC MODE AND THE ELECTRICALLY-POWERED BRAKE AND STEERING OPERATION WILL CONTINUE TO FUNCTION NORMALLY. ANALYSIS OF THE WARRANTY DATA INDICATED THAT OVER 97% OF VEHICLES EXPERIENCING A GAS ENGINE STALL RESULTED FROM AN ISSUE WITH THE PROGRAM LOGIC IN THE ELECTRONIC CONTROL MODULE (ECM) SYSTEM, WHICH MAY CAUSE THE ECM SYSTEM TO NOT START THE GAS ENGINE WHEN REQUIRED.AS A RESULT, THE VEHICLE WILL ENTER THE LIMITED OPERATION MODE DESCRIBED ABOVE.THE MAJORITY OF THE ODI COMPLAINTS ALSO INDICATED THAT THE DRIVER EXPERIENCED THIS CONDITION IN CONJUNCTION WITH THE ENGINE STALL. DURING OCTOBER 2005, TOYOTA INFORMED ODI THAT IT WOULD INITIATE A SPECIAL SERVICE CAMPAIGN (SSC) TO REPROGRAM THE ECM SOFTWARE ON APPROXIMATELY 75,000 MY 2004 AND EARLY 2005 SUBJECT VEHICLES TO ADDRESS THE GAS ENGINE STALLING CONDITION.DURING THIS SSC, DEALERS WILL ALSO APPLY SPECIAL DIELECTRIC GREASE TO A TRANSAXLE CONNECTOR TO PREVENT WATER INTRUSION WHICH MAY ALSO CAUSE SIMILAR LIMITED OPERATION CONDITIONS.BASED ON ODI'S ANALYSIS, THIS REMEDY SHOULD ADDRESS MOST OF THE INCIDENTS RESULTING IN A LIMITED OPERATION MODE.GIVEN THESE CIRCUMSTANCES, FURTHER USE OF THE AGENCY RESOURCES IN THIS MATTER DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.
