AIR BAGS
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)

SERVICE BRAKES
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.

SERVICE BRAKES
Prius have a LONG known problem w/ braking systems (over 15 years) defaulting to SOFT brake pedal that (will) kill any driver. Toyota decided to avoid a recall by paying off a few repair jobs, during warranty. They have created a new part to resolve the issue. $4000 to replace a brake pump. Most fail at 150k miles. .

AIR BAGS, ELECTRICAL SYSTEM, STEERING
I had lost functionality for some buttons on the steering wheel that didn't directly impact safety. On replacing the clockspring mechanism inside the whweel I decided to inspect the old unit. Four of the lines in the flex cable are impacted by corrosion, three have already failed. The fourth line is one of the airbag's electrical lines. I'm filing an issue report because the airbag would be next impacted by this failure and I believe there's a fair chance the corroded line could fail during the vehicle's attempt to fire the airbag on the wheel.

SERVICE BRAKES
11 months ago I had a brand new Toyota ABS brake actuator installed on my 2005 Prius. Less than a year later, it is failing again. Since I've driven the car more than 12,000 miles Toyota will not replace the part under warranty. Toyota charges $1800 for the part alone. I had an abs brake actuator fail on a previous 2007 Prius as well. Toyota forums imply this is a too common problem.

SERVICE BRAKES
We purchased our 2005 Prius in 2014, and after 7 years of learning to drive with the bizarre behavior of this Gen 3 Prius, and reporting it to the dealer (who said that's just how they are designed), I just read dozens of reports on NHTSA, all from Gen3 Prius owners, all reporting identical issues with the antilock braking and traction control systems. It is as if Toyota intentionally designed them to operate exactly the opposite of how they should. With traction control, anytime the front drive wheels loose traction - gravel, railroad tracks, even as simple as painted road stripes or damp surfaces - traction control kicks in; however, on this car, traction control immediately cuts all motive power to the drive wheels, leaving the driver vulnerable to getting hit from behind; it cuts in and out until the car decides it has enough traction to proceed. It's dangerous and idiotic. The anti-lock brakes do much the same; if one encounters a situation requiring emergency braking, when the anti-lock system initiates, the brakes simply cut out, and the car jumps ahead, until they grab, then loose again immediately, with multiple lurches, and sometimes just no brakes at all available. It is dangerous and, from the Toyota dealer where we get it serviced regularly, a constant complaint from owners. And, Toyota does nothing. There needs to be a class action addressing both of these dangerous propensities. It's an awful design. Just awful.

UNKNOWN OR OTHER
While driving in a heavy trafficed area, my car eccellerated on its own. When i stepped on the brake the car did not respond but simply kept driving at around 20 miles per hour. Magically i was able to navigated the traffic and there was no crash, but there certainly could have been and several people could have been badly hurt. I have scheduled a mechanics assessment for tomorrow.

SERVICE BRAKES, ELECTRICAL SYSTEM
When driving the vehicle multiple lights came on (ABS, VSC, & brake)! Brakes became hard to push at times and didn’t feel normal. Took it to shop and had both ABS speed sensors replaced. Warning lights went away and brakes were normal again. After a day, the lights came back on and a constant alarm started sounding! The brake system failed and the vehicle was super hard to stop! Came very close to having a major accident on the interstate when this happened!!! It took pumping of the brakes and full force on the pedal to bring it to a stop!! Went back to the shop and was told that the ABS control module/actuator went bad and needs to be replaced. Was also told that this system is a known problem in Toyota Prius’s for a long time!!!!!!!!!!!!!!

AIR BAGS, SEAT BELTS
On 9/12/21, I was driving 25-30mph when the SUV in front of me stopped on the freeway interchange suddenly and unexpectedly (other cars were not around us). I hit the breaks very hard and fast but could not stop and collided with the SUV. The front end of the Prius lodged under the back end of the SUV and the impact was enough to wreck the Prius. During that collision, the driver side seatbelt engaged, but the passenger side seatbelt did not. My preteen hit his forehead on the dashboard very hard. Additionally, the airbags failed to deploy. I could smell an odor from the dust from the airbags. The car is at a repair shop waiting for insurance adjuster to inspect. There were no warning lamps or other messages of the problem prior to the failure.
