one year after bought, was losing power, replacing a lot of batteries, headlights and lamps then car would lose power while driving, not start continually everyday for each day after and even started on its own. i took in a lot and they put my vin to the wrong person..someone rainsford so my service recs were not recorded. said no battery code, didnt check altenator, and even tho serv advisor said the break was squishy to him and he heard the loud buzz noise when pushing, it was not replaced. they tried to blame it on keys being in car which is how it starts and runs! not parked on hill or in bad temps and driven long trips, none of which SHOULD BE REQIRED to start a car to get to dying patients on time. we bought charger and use on both priuses daily. lost power while driving, got hurt, and josh's pt. died. nothing but headache nightmares. have long written records where submitted all and they just like to deny things or try to find a way to blame on consumer. my only fault was buying an undisclosed deathtrap. they need to refund us both cars and damages and expenses and our time and missed work. the shuttle was a joke. i have my own top notch code reader and it said battery was fine. it was new, yet they wanted to sell me one so they said it coded but refused to show me. they are just trying to make money and really hurting people. sending my title and all my personal info to a stranger and me catching after 7 years broght on an ID theft im still fighting. very rude front staff and drivers..sheldon.

My car is a well-maintained 2011 Prius 4 with only 88k miles on it. Recently the traction light, the tire pressure light, the BRAKE light, and the ABS light came on suddenly at once. I took it to my mechanic, who is a certified Prius technician, and he diagnosed it to be a defect in the brake booster and the booster pump (basically my brakes can stop working at any moment). He also mentioned that this was the 3rd Prius this week to come to his shop with this problem. A problem that is not only incredibly unsafe but costs $2,000-$3,000 to fix. One of his customers couldn't afford it or wait the week for the part to arrive and, against his advice, left with her car and is driving around with brakes that could fail at any moment. This seemed wildly unsafe for any Prius driver, so I went online for further information and I found a petition for a recall with 177 complaints and 60 car accidents because of their brakes failing. I also found that Toyota had issued a "Customer Support Program ZJB" for this very issue. Which is great except for all the Prius owners, like me, who never received notification. I know for a fact I would have gotten my Toyota looked at (and fixed) if I would have known about this. It's too risky not to. According to Toyota, there are approximately 946,100 vehicles covered by this Customer Support Program ZJB. That's 946,100+ people who have the risk of their brakes failing and they might not know about it. I know there is only so much that Toyota can be liable for but shouldn't this be a recall and fixable for all owners at all times? I asked Toyota about Customer Support Program ZJB and they informed me that my coverage expired only 14 days ago, so they can't help me. THIS DANGEROUS ISSUE SHOULD NOT HAVE AN EXPIRATION DATE. This should be fixable to all Toyota drivers regardless of when they first drove their car or some arbitrary date that Toyota created. We trust Toyota to keep us safe by buying their vehicle in the first place.

The brake booster pump is failing, and it is available for inspection upon request. My safety is put at risk because when it fails, my breaks will become extremely difficult or impossible to apply; if the vehicle is in motion and I need to apply the brakes at the time of (or after the) failure, I will be unable to stop the vehicle safely, putting myself and others at risk of collision. The problem been reproduced and confirmed by a dealer. Besides The Toyota dealer, the vehicle or component has not yet been inspected by the manufacturer, police, insurance representatives or others. There have not yet been any warning lamps or messages regarding the failing component, however I discovered the issue because of the symptom of a high frequency (every 25 seconds or so) of the whirring noise made by the leaking brake pump when it engages, without ever applying the brakes in between. Symptoms were first noticed approximately a week ago, or 4 days before taking the vehicle to the dealer.

The 2010 Prius will suddenly develop Brake faults. The BRAKE, ABS and Traction Control lights will light up on the panel. The cars braking capacity effectively reduces to 50% and the regenerative charging also goes missing. This is an issue when the car all of a sudden would brake with half the capacity anticipated putting the occupants and others around at huge risk. Toyota does not have a plan to fix this issue yet - they would reset the code which fixes the problem but for a couple of trips / days / weeks.. an uncertain time until this happens again. Replacing brake oil, boosters and pads did not help. I am not sure what could the remedy be, please advise Toyota to investigate and create a formal recall where all effected cars could be repaired for the drivers safety.

Around 100,000 miles the brake system has been sluggish and it appears the ABS system is failing. Currently the car has 118,617 miles and constantly exhibits sluggish and spongy braking. Hitting a pot hole or any type of bump while pressing the brakes can cause the ABS to light up temporarily and the brakes feel as if they release for 1 second and re-engage. When pressing the brakes there is a popping/air-like sound in the brake system constantly. Bleeding the brakes did not solve this issue. Through research I have discovered this is a complaint of many Prius owners about their brake actuator. It is a $1700+ part that, if fails, will cause the entire brake system to fail.

THERE WERE THREE DRIVING INSTANCES WHERE, WHEN APPLYING THE BRAKES, MY BRAKE FOOT WENT COMPLETELY TO THE FLOOR. TWICE I WAS ON THE CITY STREET AND ONCE IN A PARKING SPACE. MY SPEED AT THE TIME WAS SLOW BUT THE BRAKE PEDDLE GOING TO THE FLOOR DID NOT STOP IT. NO TURN WAS INVOLVED IT DID STOP EVENTUALLY BUT THE CAR WAS CARRIED MUCH FURTHER THAN EXPECTED WITH NO BRAKING CONTROL. THE ONLY COLLISION WAS WHEN THE FRONT END HIT A LOG IN MY HOME PARKING AREA. THE CAR WAS TOWED TO THE DEALER'S SERVICE DEPT., BUT AFTER 4 HOURS, I WAS TOLD, "COULD NOT DUPLICATE CONCERN CUSTOMER WILL HAVE TO RETURN WHEN FAULT IS CURRENT". THEY DROVE IT AND USED THEIR COMPUTER BUT NOTHING FAULTY WAS EVIDENT. I WAS SENT OFF IN THE CAR. WITH AN INTERMITTENT FAILURE, IT WASN'T LIKELY. SO, NOW I HAVE A CAR I DON''T DARE TO DRIVE AND WON'T SELL BECAUSE IT'S A HAZARD!

On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP?s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
