ELECTRICAL SYSTEM
Passenger side low beam headlamp has continued to need to be replaced. I was not made aware of a "customer service protection program" on this and when I contacted Toyota they said it was too late for the repair, electrical harness, to be covered by their extended warranty. I never received information regarding the extended warranty. They stated they sent it to the correct address. But just because you mail something doesn't always mean it is delivered to that address. Also, I had my car serviced many times at Toyota dealerships and they never informed me of this extended warranty. If I had been made aware of the extended warranty I would've had it repaired in a timely manner. I have spoken to two representatives of Toyota and they stated they could not help me. I'm wondering why this is not considered a recall issue as it does affect the safety of driving a vehicle and the lights stop working. This may not be the right place to ask this question but I'm hoping someone in your organization can help me.

SERVICE BRAKES
The contact owns a 2010 Toyota Prius. The contact stated while driving at various speeds, the brake pedal would depress to the floorboard initially without warning. Over time, the brake pedal had become stiff upon depression with several warning lights illuminated on the instrument panel. The vehicle was taken to an independent mechanic where a code reader confirmed a defect with the braking system. The vehicle was then taken to another independent mechanic where the vehicle was diagnosed with a defective brake booster. The mechanic then informed the contact of NHTSA Campaign Number: 13V235000 (Service Brakes) which was linked to the failure. The dealer was notified of the failure and informed the contact that the vehicle was not included in the recall. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 153,000.

SERVICE BRAKES
Prius Gen III has a known defect with failing Brake booster parts. In Nov 2023, while driving my 2010 Prius (~160K miles), suddenly brake, ABS, Traction control, skid indicator lights popped up on the dashboard and I have lost the ability to brake effectively. There was a brake pressure loss and I had to slam hard the brakes to slow the car. The error code was 'C1391' and the mechanic diagnosed it as failure of Brake booster parts ABS Brake booster pump (accumulator) - part#47070 47060 and Brake master cylinder (actuator), part#47050-47140 and he replaced both these parts. Toyota is aware of these failures which are very frequent and hence they issued a brake booster “customer service program” ZJB - which extended the warranty for these parts. But many of us were not covered by this warranty either because of the time or mileage restrictions. This was a costly repair and we had to fix it out of pocket at the cost of ~$3000 as this is safety hazard without proper braking. To make matters worse, 3 months after the repair, the newly installed parts failed again and I had to go through the same repair. I called to Toyota to complain about this and they cannot do anything about it and advised me to report it to NHTSA.

UNKNOWN OR OTHER, SERVICE BRAKES, VEHICLE SPEED CONTROL
My car accelerated significantly on its own while I was pulling into a parking stall in a private parking lot. It caused my vehicle to jump a curb and accelerate up a dirt divider and push over a bush that was planted in the dirt divider. Depressing my brakes did not Decelerate the car, so I pressed the Park button to eventually stop the vehicle. I’m not sure what speed it was traveling when it accelerated, but I could smell burning rubber at the end of the incident. I’m not sure when the smell first occurred.

SERVICE BRAKES
Brake booster assembly failure. Code C1391 - accumulator pressure leak. Toyota previously agreed to extend the warranty on this part on this year of Toyota Prius due to the known issue and the time limit for this repair was set to be in 2019. Toyota agreed to replace the unit only if it fails before that timeframe. My Toyota got recently affected by this issue resulting in over $3,000 estimate for a repair as Toyota no longer covers this repair for my vehicle. That’s a known issue with this part, Toyota knows it’s faulty and yet no recall has been issued. Now I have to pay for a repair out of pocket. I can’t drive the vehicle until it’s fixed. This should be handled as a recall with all faulty units being replaced regardless of millage. A few people opened lawsuits on this issue before and some got a settlement. I believe there is enough evidence that this should be classified as a recall and a free of charge repair should be provided to the owners. The brake booster unit has been buzzing a lot for quite a few months ( due to the pressure leak it had to work more than normal). Now it completely failed with the leak being so excessive that the brakes are very soft.

WHEELS
I had begun to notice a slight shimmy at highway speed for a few days, but it wasn't pronounced enough to cause concern, especially since the weather was very windy and already subjecting the car to heavy crosswinds. On Monday, [XXX], the shimmy became suddenly more pronounced, so I pulled off the highway ([XXX]) and parallel-parked on street in Cambridge, MA. While parking, I heard a loud creaking and grinding sound, and the car no longer responded to steering inputs. I exited the car and noticed the rear driver's side wheel protruding at a strange angle from the wheel well. I called AAA and the tow truck driver discovered that, behind the wheel, where the wheel meets the rear axle, the arm had rusted clean through. In other words, the wheel had completely fallen off, and was being held to the car only by the brake line. I was towed to a mechanic in Salem, MA. Both the Salem mechanic and the AAA tow truck driver said that they had never seen anything like this in all the years they'd been servicing cars. I told them that the car had never been in a flood or otherwise involved in the kind of extraordinary event that would cause more than typical rust exposure. Had the wheel come off at highway speed, I could have been seriously injured or killed. The issue did not seem to have been caused by driver/owner oversight or normal wear and tear. It seems highly unusual and potentially indicative of a defect or manufacturing error. I hope other 2010 Prius owners are aware of the vehicle's susceptibility to this issue. And I would like Toyota to take some responsibility for the high cost of repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES, HYDRAULIC
The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed and attempting to slow the vehicle, he became aware that the brake pedal required excessive force to bring the vehicle to a complete stop. The service brake warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the brake booster and brake master cylinder. The vehicle was not repaired. The vehicle was then taken to an independent mechanic, who confirmed the diagnosis and additionally found that there was a leak in the brake fluid accumulator, resulting in low brake fluid pressure. The vehicle was taken back to the dealer, who added brake fluid to the braking system, which seemed to temporarily resolve the failure. The manufacturer was not notified of the failure. The failure mileage was 140,000.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
Total malfunction at highway speeds. Very unsafe, the car completely shut off. This may have resulted in a highway fatality due to collision as the vehicle was in the fast lane. NTSA please do your due diligence and investigate the faulty, defective HYBRID system as I believe the faulty inverter recall is much more larger than the original recall

SERVICE BRAKES
[XXX] We took in 2010 Prius to Toyota Dealership in Pharr Texas because road hazard light, ABS , Brake and low tire alarm came on while driving car. They ran diagnostic and found out that the brake pump assembly and brake cylinder assembly has to be replaced. We called Toyota Cooperate to ask for assistance to pay for cost and after 4 weeks of reviewing issue they said they could not help us because the CSP had expired. This car was given to us by a friend of ours and they had not used it for 2-3 years so we got it we repaired and got car running again. After we drove it we came across this problem with the brakes. This car was was built in the same plant as the other recalled cars going by by the vehicle number . We believe that the CSP should be extended or changed to a Recall? Will you help us or direct us to whom we can contact with this safety issue? I have the Toyota diagnostic report from Toyota and Toyota Corporate Letter on email.

SERVICE BRAKES, ELECTRICAL SYSTEM
My 2010 Toyota Prius hatchback suddenly had 4 or 5 warning lights appear on the dashboard and my brakes failed to function properly. It felt like the power brakes was turned off ! Although I did get the vehicle stopped, it surely was a dangerous situation. I understand that Toyota knows about this problem, and have read that it was warranted if this happened before 150,000 miles. My Prius has approx 167,000 miles right now and to replace the Brake Actuator, the cost will be $ 3 - 5 thousand dollars…absurd amount in my opinion. Since this critical feature (brakes) has a long known history of being faulty on Toyota vehicles it should be warranted for at least 25 years and at least 300k ! My Prius is “unsafe to drive” and is nothing more than a paperweight…I repeat, Toyota knows, and has known about this defective brake actuator problem for years and years!!! Please lean on Toyota to up the warranty of this faulty brake problem for the MANY, MANY Toyota owners who have purchased the Toyota product and and NOT screwing the public like they are doing now !

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS
A warranty extension went out a few years back that said one might receive a "CHECK PCS SYSTEM" warning on the dash. This has happened to us, along with 7 other lights on the dash. Between the brakes being much less responsive, and all of the pre-crash warning / adaptive cruise / radar features being disabled, this could have caused an accident. The dealer checked out the car and states that the brake actuator has a leak and that it will be a costly repair - no less than $3000. This suspiciously all happened *just* outside of the warranty window (we are within the allowed number of miles but just out of time), and also suspiciously after Toyota released an upgraded version of the actuator, and *also* after a bunch of people are experiencing the same failure. Our best assessment at this time is that the brake actuators have a factory defect and that a recall should be done.

SERVICE BRAKES
The brake accumulator has failed on my prius which then deactivates regenerative braking, traction control, abs, and stability control. The lights for traction control, ABS, and stability control and parking brake are shown on the dash. The result for the driver is that the brake pedal has the same pressure, but does nothing until about 25% of pedal travel. At this point, the mechanical brakes will engage and provide a very sudden and jerky application to the brakes. In other words, a very non-linear brake control is present and is incredibly difficult to predict. If this vehicle is operated on the motorway, the safety of the vehicle's occupants as well as others on the road is greatly reduced. Street Toyota has confirmed this issue and its effects. They want to charge $3600 to fix this issue even though the car is only worth $5k. This problem has been investigated in the past buy Toyota and the NHTSA. Toyota has applied an extended warranty for this part meaning that they will only replace it once it goes out. They also failed to notify their consumers about this matter. It is a serious issue that has put many lives at risk and has caused multiple injuries. It is a matter that should not be ignored by either the NHTSA or Toyota.
