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

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.

Brake/ABS and stability system failure. Possible actuator or accumulator. Touota knows there is a fault and hides behind a software update. System fails and causes unreliable braking with increased force to apply the brakes. Brakes apply so hard at times the rear passengers heads hit the rear seat.

Car worked flawlessly and we maintained it regularly. Took it in to address recall of jov update pwr mgmt ECU at dealer. Dealer completed recall work. 2 days later engine lite check hybrid system and the ! on and triangle on. The car continued run but now was studdering when was not before the recall work. Took it back to the dealer and he said we need a new hybrid battery. We believe the software update they did created a this issue. Dealer acting ignorant and saying it needs new battery because of number of miles on car. Asked for diagnostic print out from when they did recall work to they new diagnosis and they would not provide. We believe the recall update created a technical problem with our hybrid battery. We also believe that dealer not being honest regarding issues with this recall update and is using it as an opportunity to reduce liability for Toyota on failed recall work and to use it as an opportunity to bring in large ticket sales repair ie they quoted us a new hybrid battery for 5,500.
