While driving on a highway at night around 60 mph, brake light turned on then AB light then slip light. Nothing else happened but since this hadn-??t happened before, I pulled over, turned off car, waited a bit then turned back on. Car still worked although these lights stayed on. Continued driving to get home at reduced speed (around 45-50) plus with blinkers on with mental note to take to the dealer next morning. A few miles out, a loud unchanging alarm went off and I couldn-??t use my brakes no matter how hard I pressed on them. I was able to glide off an exit that was near and making right turns get into a lot. Also neither of the brake pad nor the parking button was working so I couldn-??t stop the car but then I hit power to shut down and that was able to stop it. Called for towing to dealer the following day. They say it-??s the brake booster and that I have to pay out of pocket since it passed a recall but this is a dangerous issue with the car. If the light had been red and a car crossing, without brakes I would have gotten into an accident and since I bought it used last year, I wouldn-??t have even known about this being an issue. There shouldn-??t be a date limit on this recall, if models of Toyota Prius needs the recall and it hadn-??t been done by previous owner, it needs to be done as this is a really traumatizing and potentially deadly issue.

The headlights on my car would get very dim and would burnout within 4 to 6 months. As time has past the time between bulb replacement would get shorter and shorter. At this point when I plug replacement bulbs into my car the burnout instantly. Without low beam headlights I am required to drive with my high beams on at all times. The dealer and the manufacture know about the problem and there was a notification regarding this issue with the headlights, but I was not sent this notice. Had I been sent the notice from Toyota I would have brought my car into the dealership for them to inspect the light problem. From what I have learned from Toyota is that there was never a recall on this issue. Headlights on a car I would think would be considered a major safety feature and should not have an expiration date on such a repair issue. The program to fix the issue was called Customer Support Program ZHB which allowed the dealers to correct the problem. How would anyone know that there was a problem unless they get a notification.

Check hybrid system light ignites, slows down vehicle in middle of high speed highway. First incident November of 2020 then several incidents after. Repair shops don't assure problem according to error codes & they recommend possibilities they cannot assure will resolve the problem. Car was taken into local dealership after receiving recall notice for software and airbags prior to November 2020 when the issue began. Software update took a couple of hours. Restart/reboot temporarily allowed driving again. Most recently the system entirely shut down & the car will not start or run. Abandoned car on side of the road and got heat exhaustion from walking the rest of the way home and had vehicle towed. Error lights come on including "check hybrid system" says "shift to P position when starting" and will not allow start.

My problem began when I pressed my brakes and instead it accelerated. I thought maybe my foot slipped and didn-??t know what it meant. It happened again a few weeks later and then all of the dash lights went on that indicated that I had to have the big brake recall repair. Being that my car is past the 10 year warranty and past the extension for mileage, I had to pay out of pocket. This repair was done and upon receiving my car back, the gas mileage instantly began to drop. It went from averaging 42-48MPG in my town to 25-30MPG. I took it in the be looked at and they ensured me nothing was wrong with the car AT ALL. The battery wasn-??t holding charge on top of this and it wasn-??t reading the same on the dash about the 0-100 current gas mileage you-??re getting as you go (the lines scale thing) that goes up when you let off the gas, and I could feel a strange shift while I was driving so I took it in again. They told me this time it-??d be $110 to diagnose even though it was the same issue that started after the brake system repair, so I left extremely upset. A few days later my cars steering went out while I was driving and the whole hybrid system died. The car now only works in power mode. The consumer stated the car was taken in for a brake recall and had to pay $2800 in repairs. The consumer stated what they thought was a battery failure turned out to be the beginning of an electrical motor failure related to overheating.

I was just told that my 2010 Prius needs the brake boost assembly (cylinder and boost) at a cost of $2,570. It was causing my 4 month old, 12V battery to drain. I thought that was outrageous so I looked into it and found out there was an "enhanced extended" warranty issued (not a recall), but for my vehicle it expired April 2020. Another issue that I uncovered that this part also causes the Prius to lurch forward when braking and you happen to drive over a bump. Train tracks, or potholes which is a safety issue. I have also experienced this with my Prius. Fortunately, I have had no accidents so far. I have read that there have been accidents caused by this issue. Toyota should step up and fix the problem before people are injured due to this defective braking system. My daughter drives a 2015 Prius. Is anything more being done" or are they going to wait until more accidents happen" I stumbled across this issue when my 2010 Toyota Prius 12V battery required frequent jump starts. I replaced the battery ($300) Dec 2020. Prior to that, I called aaa and got a jump start. Because of covid, I wasn't driving the vehicle daily (work from home) so it was assumed the cause was the vehicle should be driven frequently.

I was driving on the hwy with 3 children when it cut off on me and my steering wheel was locked. I took it to four mechanics I saw the Toyota dealer and they told me that it was my battery and now I know that I have a recall on it. I have not driven my car in three months I'm also still paying payments on it. I also was told that it was my break. I bought a new brake booster and pay for the replacement and the problem was still hungry just

I have experienced problems with the electrical, oil, and break systems ever since purchasing my certified pre-owned 2010 Prius from the dealership in 2013. Toyota has never provided a satisfactory answer for what is actually wrong with the electrical system; the problem still remains. Toyota also does not have an ideal maintenance plan set up for the known increased oil consumption rate that is directly linked to my model vehicle and has not only not performed routine oil changes but also sent me home after a supposed oil change with zero oil in my tank. But today my main concern that I take issue with and that ive encountered from the get-go, has to do with the breaks. For years I've been telling Toyota about how my breaks do this thing where under the right circumstances (those being things like slight bumps or raises in the road, or going over a manhole cover) the breaks not only give out but actually propel me forward with zero chance for stopping which is quite terrifying already and then when you add in other drivers on the road into the equation is a literal nightmare. Despite my many efforts for Toyota to take a look at them they always refuse any service to them because my dashboard is not displaying any warning signs. Also, due to the fact that its not a constant issue, meaning it only happens under the right circumstances which idk where such a precise place exists near the dealership, they cant experience it for themselves. So my concerns are dismissed leaving me to fend for myself whenever these circumstances arise which no doubt an accident seems to be on the horizon. Then with ~114,700 miles on the odometer, my entire ABS system crashed while I was in traffic. Luckily I am a beyond exceptional driver and also have catlike reflexes so was able to manage my way to the shoulder of the road when this occurred. However, with warning lights now illuminated O

The contact owned a 2010 Toyota Prius. The contact stated that after driving his vehicle for seven hours, the contact had parked the vehicle in his friend's driveway. Thirty minutes later, the contact's friend received a knock on the door from a fireman asking him who owned a Prius. After the contact identified himself as the owner, the fireman informed him that his vehicle was involved in a fire. A fire report and police report were filed at the scene. No injuries were reported as result of the fire. The vehicle was destroyed by the fire and was towed to an independent junk yard. The contact notified the manufacturer of the failure and the contact was given a case number. The contact was also informed that an investigation would be launched regarding the matter. The contact had sent photos and email correspondences to the manufacturer; however, he never heard back from the manufacturer. Upon investigation, the contact discovered a recall on his vehicle under NHTSA campaign number: 18V684000 (hybrid propulsion system) which he linked to his failure. The contact had not spoken to a dealer about the failure. The failure mileage was 77,000.

Prius has less than 100K miles and has been running perfectly. Today while driving, the brake, ABS and traction control lights came on simultaneously and began alarming, while suddenly my brake locked up. This could cause accident and injury if it occurred under the right circumstances. Apparently there was a previous brake booster recall that I was never notified of and which has since expired. This recall should be reissued to include the many 2010 priuses affected by this problem.

My ABS system started showing signs of problems, and I started getting codes for all sorts of brake-related issues. My brakes ended up locking up and not working, and my battery in my car died because it was the brake system was not able to recharge my battery. Even though I started having issues with it in February, apparently Toyota said that because I had a 2010 Prius, that since November 31, 2019 had passed, the recall/extended warranty "ran out" on it. Even though this is a problem that obviously wasn't fixed in the first place. So when I took it to the dealership to get a diagnostics ran on it, they said that they needed $3,200 to fix the vehicle. This included both the purchasing and installation of a new brake booster/master cylinder assem and an ABS pump motor assem. I obviously do not have the money for the repair and they are telling me to go kick rocks. This is not right and because of the brake issue not being fixed in the first place, it then allowed my battery (which runs around $1,500) to get completely drained and prevented it from being properly recharged by the brake system.

I own a 2010 Toyota Prius with 97K and it is immaculate. In March 2019, the instrument cluster (an electronic component in the dashboard containing the gas gauge, speedometer, and gear position) stopped working entirely one day upon starting the car. I researched the issue and it's my understanding that a faulty capacitor on the logic board within the instrument cluster is the culprit. Toyota can replace the instrument cluster but only at my cost and for over $1000. Toyota issued a warranty enhancement notice to extend manufacturer warranty on this instrument cluster problem, but it only applies to 2004-2009 models. This electronic issue had not been entirely resolved by Toyota in later models as many others are faced with the same issue. Am I monetarily responsible for the repair of the instrument cluster" does NHTSA have ongoing support to Prius owners for this issue? should I file a small claims lawsuit"

Both the low beam lights are of a problem with recall which Toyota expired the recall on 10/31/2019. I tried few times last 3 years to get it fixed with Toyota portland but they always said 1) don't have parts will call back once available 2) if you have issue we will fix it otherwise now now. Now that both were off and I had to use high beam, I took to Toyota beaverton, or. They said recall is expired. Why will recall expire if it is safety issue? I called Toyota customer support they said expired and you have pay fo yourself. The cost is not just bulbs but internal wiring kit which starts from $600. I am taking it to Toyota portland today as my student daughter needs the lights to drive. We are both in different states (ca and or).

While driving back from running errands my car's lights on the dashboard started to come on and noises started to start happening. I was lucky I was only a few streets away from my house so I decided to drive back home. The break was really hard to press. The brake felt like it was a rock and hard to press. I drove with my hazards on unsure of what could happen while driving. There was something wrong and the car started to beep and I was worried the car might fail to brake so I started to drive very slowly. The brakes were so hard to press. I took my car to Toyota the next day and they said there was a defect with my brakes. They had the vehicle for a few days and returned to me saying it was fixed. Needless to say this was a very scary situation to be in. I drive a lot. If I had been further away from my home this would have put me in a very dangerous position. I could've been stranded or drove on the freeway in this condition unsure of what was happening. My car could've stopped braking, I could've gotten into a big accident and injured other drivers around me. This is a very serious issue that should be recalled now and save other drivers! in California people drive up to 80 mph on the highway-if we are behind a car and the brakes malfunction you can imagine what will happen to the driver and anyone involved! when I heard Toyota was not recalling this on all Prius's that might be affected it really scared me. This is unsafe.
