Brake Light On Problems of Toyota Prius - part 1

While driving on the freeway, all of a sudden the abs, slip indicator, brake, and brake system lights lit up on the dashboard. I immediately switched lanes to one that had no cars in front/back of me since I was going about 55mph. I tested the brakes since I saw the brake lights appear. It felt as though when the brake pedal was pushed, they didn't activate until you reached a certain point, almost to the point where the pedal needed to be fully pressed to stop. It didn't feel like the brakes were fully functional and behaving in the way they were prior to the lights appearing. I was afraid the brakes would give out. Then I noticed a whirling/hissing sound that was consistent. The sound was easier to hear when the car was at a complete stop but it could still be heard while driving. We took the car to a local Toyota dealership/service dept to get it evaluated. They diagnosed the car saying it needs immediate attention and is not safe for driving since it involves the brakes. The repair invoice stated various brake warning lights on c1391.

Prius displayed all brake warning lights when car was running. Toyota dealership confirmed that brake booster and pump assembly need to be replaced, but would not replace them under customer support program 20te07 because they could not pull the specified diagnostic code. Dealer acknowledged that the battery dying two weeks prior could have erased the necessary codes, but still refused to fix the car. After calling the corporate customer service line and speaking to someone for 30 minutes, they stated that Toyota could fix the problem, but made a business decision not to.

The traction , abs and brake light comes on after driving over a small pothole.

Regenerative brakes stopped working while driving in clear conditions on the highway at 60mph, abs, traction control, and brakes lights on dash illuminated. Almost crashed as brake pedal needed to be pressed really hard and almost to the floor to stop the car. Known issue and dealer refuses to fix the problem.

I bought this car brand new in 2010. Toyota Prius hybrid. Two weeks ago the abs light, emergency brake light, and traction control lights all came on and won't go off. Dealership says I need $2000 worth of work. Brake booster/master cylinder, brake booster pump assembly, brake actuator internal leak. Brakes acting weird. Dealership says I don't need to drive car, just pay $2000 which I don't have. They said Toyota extended the warranty to December 2020, which just past. I never got letter saying it was a problem.

Brake actuator has failed. The brakes no longer are getting pressure, and require a lot of force on the pedal to stop. The brake light is on, as well as abs, vsc, and ! lights. Apparently this is a known issue, and Toyota was fixing these under warranty up to 10 years / 150,000 miles, whichever came first. My car has 128k miles, but it's more than 10 years old, and thus, the faulty part is no longer covered under the warranty.

My Toyota Prius 2012 with 95k mil. Abs, traction and brake lights came on while driving on highway, the breaking wasn't like used to be, it was mushy after the warning lights, took it to Toyota dealership they estimated $3500 for the brake replacement the fault codes c1241, c1247, c1391 found break booster and pump assy, needed. This should be recalled by Toyota, its safety issue, I have owned the car since it had 41k miles and regularly maintained the car throughout my ownership period.

Abs, traction, and brake light stay on. It is the actuator brake and the cost to fix is over $2000. I have researched this issue with other 2010 Prius' and it is a common issue. This is a defect that Toyota refuses to fix even though it is very common and puts many people at risk.

I was driving down the highway and the traction control, abs, and brake light all come on. I go to use the brakes and the pedal was a lot firmer and was harder to press. The car makes a buzzing noise I believe it is the brake accumulator. I go to the nearest place to get the codes read. It came up with c1391 and I look that code up and it comes up with that code is a common issue with the Prius. I read that it could lead to brake failure.

The contact owns a 2010 Toyota Prius. The contact stated that driving at 15 mph, the brakes failed to operate as needed upon depression of the brake pedal. The contact stated that several warning lights appeared on the instrument panel including the abs, tire pressure, traction control and emergency brake lights. The contact was able to drive the vehicle to haley Toyota of roanoke (1530 courtland rd ne, roanoke, va 24012) where she was informed that there was a crack in the brake booster pump assembly accumulator, a decrease in the hydraulic pressure, and a defective brake master cylinder. Upon investigation, the contact linked the failure to NHTSA campaign number: 13v235000 (service brakes) however, the VIN was not included. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 162,000.

My 2012 plug-in Prius came up with a c1391 code. The abs, brake and brake skid lights came on. I have no re-gen braking and when I actually brake it seems very sluggish.

Dash went out no visual, twice, 1st time I unhooked front cable to battery, it come back on, 2nd time, I started car, consol went out again, had to take it to Toyota place, to order new consol, brake light on, asb light on, after replacing both front & back brake shoes, enjector pump went out.

Brake light, abs,slip indicator,brake system warnig light system all came on while driving at high velocity [75m/h] in the rain and lost 75% of the braking power plus the car started to slide. Needless to say this was a catastrophic failure of the entire brake system on a car that has a customer support program notification from Toyota[zjb] that was sent to me with a warning of such occurrence. This is down right irresponsible to a major car manufacturer to allow these vehicles on the road without testing the entire system on each of these affected vehicles and with for a catastrophic failure to occur and cause public harm or even death. I had just taken the vehicle for service a few weeks prior where I explained the service advisor of an issue with brake pulsation. However, the entire brake system was not throughly checked and was just told that its the front rotors that are uneven, thank god I did not fully loose control of the vehicle and cause a catastrophic accident as it would have resulted in bodily harm to my family. I expect this federal government agency to use it's authority to prevent such occurrence to the tax paying citizens of this nation.

Abs , traction control,brake lights on. No power assist brake, no abs, no traction control.

I own a Toyota Prius 2007 and I experiencing brakes not engaging as they should when applied. I notice my abs vsc brake lights are on my dashboard. I took it in to a shop and was told I have a bad abs actuator. I researched it on the recall list and it was listed but expired in Dec 2017. Toyota should fix this problem. This was a known problem.

Started getting brake actuator failure noises in my 2007 Prius back in March 2020 and took it to the west coast Toyota dealership in long beach, CA. They didn't find anything wrong with the abs system even though the grinding noise I now know is commonly associated with the problem was going off. The other day the abs light warning came on as well as the emergency brake light. I pulled over on washington blvd and arlington in los angeles and when I started the car again and started to move forward I had no control of the brakes and turned the car off immediately. From what I've read this is extremely common! Toyota extended the warranty's on many of their vehicles to 10 years but there were no recalls so if this part malfunctions a day after the warranty then you are out of luck. The brake system is just about the most dangerous part to fail. I can't imagine what would have happened if the same thing happened at a higher speed.

2005 Toyota Prius, base model, 136,600 miles, meticulous service history, recalls serviced, safe driver. At 45mph abs, (!), and brake lights came on dashboard. Parked, turned off car, and checked 12v battery and brake fluid levels�fine upon inspection. Brakes became spongy upon startup. Limped car to dealership and was told abs actuator had failed, destroying front brake pads and rotors at same time. Quoted $3,600 repair estimate; car worth $4,000. Recognized Toyota issue�TSB with a warranty extension offered (zg1). This also occurs on gen 3 Prius models (2010�2014 , zj1 extension). Fortunate to have not wrecked, but the repair cost has totaled the vehicle.

While driving around a corner on city streets, braking suddenly became very difficult, and caused the vehicle to skid when brakes were applied. A high-pitched electronic squeal came from the dashboard, and the brake system light, abs light, vsc light, and master warning light all turned on. These are all listed as symptoms of a failed brake actuator. After contacting a licensed Toyota dealership, I was directed to the Toyota customer care department. After being escalated to a supervisor, I was informed that Toyota is aware of this problem, but that the warranty extension they used to cover it expired in 2017, and they refused to cover the cost of replacement (~$3000). I believe this issue should be cause for a safety recall, as it happened suddenly and without warning while the vehicle was in motion. It was pure luck that this didn't result in a crash.

2011 Toyota Prius. Consumer writes in regards to defective brakes and electrical issues. The consumer stated the master warning light, air bag light, slip indicator light, and brake sysytem light all illuminated.

The red brakes light, abs light and the 'yellow skidding car' icon lights all come on together, but intermittently. The brakes often feel difficult to press down upon starting the car. Ofter when the lights are on, the brakes feel spongy, or as though they may not stop the car. I took the car to the Toyota dealership and they concluded that the master cylinder and other parts needed replacing. I found out that Toyota has had lots of problems with these brake cylinders.

I was driving my car on the highway and suddenly my brake warning light, abs warning light, and other lights came on as well as a constant beeping noise. The brakes almost stopped working completely; it only worked about 10%. My foot was all the way down on the brake pedal, but the car was still moving. I was able to pull over, but this issue left me in a compromising position for my safety and could easily have been involved in a serious accident from it. The warning lights go away after turning off the car, but then they come back on randomly. Based on what I've read online on similar issues, I believe this is an issue with the brake actuator.

I was driving when the abs, brake system, and parking brake light turned on. The brakes became very mushy, I was trying to stop, and I could hear the brake actuator motor buzzing and making a groaning noise.

Brakes went out. Hydrauli control assembly antilock brakes modulator valve. Toyota wants $3,806 to repair it. There was a warranty extension program that ended December 2017. This should be on recall, tons of problems. I am the second owner of the vehicle, purchased April 2017, but was not notified by Toyota of the warranty extension, or that it was ending. I was driving the vehicle, all brake lights came on, Toyota says not to drive due to risk of complete loss of braking system. Case number 10664 has been filed with Toyota.

Traction warning light, brake light and abs light all came on at same time while driving on the highway. I was told by a Toyota dealership it is a malfunction with the brake booster which is roughly a $3000. 00 repair job at Toyota dealership. Customer support program "zjb" was created by Toyota north America for this issue in response to thousands of Prius models experiencing this severe malfunction, however, my 2010 Prius is no longer eligible for coverage for this repair, even though other Prius models are still eligible for complete coverage for this repair. This is a safety hazard and Toyota north America needs to stand by coverage for this grave malfunction for all models regardless of year or mileage. The dealership told me the car is not safe to drive, the brakes are not operating at full capacity. This is a safety hazard and happened while I was driving on the highway.

While driving on the higway the abs warning light, brake light and traction light all came on at once, took to local Toyota specialist, diagnosed the code as c1391, an abnormal leak in break booster accumulator. Mechanic informed me that this issue was previously under safety recall and my vehicle had the proper repairs done, clearly this is an ongoing safety issue with this vehicle that is not being properly addressed by Toyota. It is also an extremely expensive repair which Toyota needs to be financially responsible for.

Had the traction, abs, and brake lights all pop on. Braking feels a little different now. C1391 code was given by mechanic. He is talking about brake parts that will cost parts and labor around $2500. I can't afford this and I need a car to drive, so hoping no wrecks. We are a Toyota family with 4 now in the family. Called to complain to Toyota headquarters and they said out of warranty, but they did recall the 2010 models, even though the same problem is with the 2010-2015 and some other Toyotas. They basically blew me off.

Toyota USA failed to honor repair defect within the brake booster pump assembly. When this defect occurs, various warning lamps on the instrument panel made illuminate, I experience increased stopping distance, reduced hydraulic pressure within your brake system, the deactivation of brake assist, & the deactivation of vehicle stability control. Toyota previously issued at least 2 safety recalls. Designed to prevent similar dangerous occurrences. However, hundreds of thousands of Prius models 2010-2015 were excluded from those safety recalls including my 2010 model. As of today Toyota USA filed case number 2005052305. Safety recall in torrance California dated June 4, 2013 stated Toyota sales USA was conducting a voluntary safety recall involving over 87000 model 2010 Toyota Prius however I called Toyota today and the insisted my vehicle was excluded even though in barely has 100000 miles we just began to experience these brake symptoms. Customer rep insisted it was Toyota voluntary recall not enforced so my vehicle did not even qualified for a customer support service. Please help us have Toyota fix this safety issue ASAP before someone has a mayor accident. Warning lights for abs, stability control, and warning lights all came on at once. Brakes became spongy when pressed. Was able to still brake but with much more effort and not confident in the braking. I had it towed to a local mechanic and the diagnostic error code registered "c1391". Per mechanic this is for abs accumulator, or booster pump failure or leak per mechanic. This happened out of the blue, no warnings. Per Toyota the part required are cylinder assembly brake and brake pump assembly. Cost to repair these parts per Toyota would be estimated at $2700. . Attached video of actuator's loud noise it produces & dashboard showing abs failed& brakes lights/also failed attempt to solve this with Toyota USA.

The Prius have been great and have been serviced with oil changes, spark plugs etc. It runs like a champ with 159k miles, but all of a sudden one day, the traction control, abs, and brake lights all came on at once. The brake pressure feels softer and that whirring noise is heard every few seconds. Dealership said it was the brake actuator and would cost 3k to fix. Apparently there was an extended warranty for it but it ended in November 2019. Attempted to call Toyota, but no help.

While driving the vehicle a sequence of 4 lights appears on the dash- 1. Brake light 2. Master warning light 3. Slip indicator light and 4. Abs (anti-lock brake system indicator light). When this happens the vehicle's power braking system goes into what seems to be a manual mode making the pedal hard to press and brakes to malfunction, it is so dangerous. I took the vehicle to my local Toyota dealer and they confirmed fault code c1391 (abnormal leak in the accumulator) and the "brake cylinder assy. Abs pump, part # 47050-47110 is defective. The estimate given by the dealer for my repair was $3040. 00. After doing my research on the condition, it was discovered that Toyota has issued a warranty enhancement letter coded "zjb" for similar Prius vehicles of the same year span as my vehicle. After contacting Toyota, they stated the enhancement is VIN-specific and the Prius v model does not fall within the "zjb" enhancement. The enhancement currently applies to 2012-2015 Prius and Prius phv vehicles, but not the Prius v. The program offers complete repair, at zero cost to the customer. It is my position that the Prius v should be included in this rework as it affects the same components, same fault codes, and same symptoms affected on the covered models. Toyota is well aware of the issue with these abs brake pumps going back to their 2010 cars. It is also my position that since there are less Prius v models on the road, there just hasn't been enough complaints to make it relevant. I currently have an open file with Toyota, the file number is 2005133097. At this time they have agreed to make some adjustments on the repair costs, however, Toyota should be required to add the Prius v model to the "zjb" warranty enhancement rework letter. There are many other Prius v model owners that this issue is affecting and not being treated fairly by Toyota. Please do what you can to help.

This is something that's happening occasionally, I'm driving and all of the sudden, the traction control, abs and brake lights, turn on and the brake pedal feels sluggish and starts to apply at a dangerous low level, the pedal almost hits the floor, then a day may pass, then it starts normal again, for a couple of hours, then, the lights come on again, and the pedal starts with the problem again, it's getting very dangerous for me to drive the car. That happened with my youngest son and my grandson, this started at April, and it still doing it 'till this day, please help.

2008 Prius abs and brake lights came on, front passenger tire locked up suddenly almost causing daughter to run off the highway. I drove the vehicle and could not duplicate the issue. 9 months later the abs and brake lights came on again, Toyota cleared codes could not find anything wrong and released the vehicle back. Lights returned the next day. Toyota now states needs a new brake actuator for $2700. Toyota has bulletin gz1 with over 171 complaints on your site with not counting all the vehicles repaired under this bulletin. They will not fix the vehicle without payment of almost half of the vehicle's worth. Contacted Toyota customer service and they were not willing to assist with a known issue. With the risk of accidents when brakes lock up or fail, why was this not a safety recall instead of a "silent recall" warranty extension.

When I go to hit the brakes the car won't stop and the rear end makes noise and raises up. The abs and brake lights are one as well as maintenance required and srs airbag light. The master alarm buzzer is on and won't go off. Brakes engaged without hitting the brake causes rim to overheat and brake fluid gets extremely hot. Also sometimes when tap on the brakes they will lock up and you will go sliding sideways or tap the brakes and they straight to the floor. Also the brake actuator starts whining noise and won't go off even if the car is turned off. Don't have documentation from a mechanic but can send video of driving it.

I was driving on the highway at about 60 mph when the brake light, abs light and slide light illuminated on the dash. I took the car to the dealer and they said it was the brake actuator. When I researched this,I found that it is a known problem totoyota and they did a voluntary recall. My question is why would there be a voluntary recall on a part that is vital to the safety of the car and has a known defect? because it was a voluntary recall they could arbitrarily select a cut off (150,000 miles) instead of ensuring the car was safe. This is only for 2010 Prius.

A few weeks ago my brake and abs lights came on and my brake pedal changed and became spongy. Since I was still able to brake, I kept driving the car and became used to the spongy pedal. Then the other day I was returning home from work when the car in front of me suddenly hit his brakes. I had to quickly hit mine as well and the brakes locked up sending the car sharply to the right and I crashed into the guard rail causing $1500 worth of damage. I picked up the car today after having the damage repaired but I still have the same problem.

Upon starting the vehicle it makes a high-pitched beep, followed by a buzzing sound that repeats every five to eight seconds. The dashboard displays the tps, abs, vsc, and brake lights. When putting the vehicle in drive, the high-pitch sound returns for one to two minutes. During that time the brake pedal becomes impossible to depress. If the engaged, the vehicle does not stop until the brake pressure returns. Once the sound stops, the brake pressure returns to normal. Diagnosis from Toyota shows: code c1256 = accumulator low pressure. Code c1391 abnormal leak of accumulator pressure. Estimate for repairs = $2,811. 72. At present the vehicle is unsafe to operate as Toyota advised, in the vehicle's current condition the brake system could fail at any time.
