general problems of the 2007 Toyota Prius - part 1

The brake actuator failed. When the car was diagnosed by the Toyota dealership, they identified the problem as an internal leak within the brake actuator. Luckily, nobody has been hurt attempting to drive the car, but it is still being driven to get it from home to the repair shop so anything is possible. The first symptom I could link to this was in 2023, when the car would not accelerate via the gas pedal after the brakes were pressed during cruise control. Turning off the car and turning it back on fixed the problem. Afterwards, the red brake symbol was turned on. From that point on, the brake light would only shine sometimes. Leading me to believe there must not have been something wrong with the car, since nothing else happened after that. 2024 is when the red brake light and abs symbol both lit up. The only information that I could find in the manual was to take the Prius to the Toyota dealership. I could not find details on the problem. I continued to drive the car regardless because there seemed to be no problem. After letting the car sit for a few months in 2025, I began driving it again, and it was fine. A month later, I turned on my car and was met with a loud beep that did not end. This was my final sign to take it to get repaired. The car has exceeded 200,000 miles. This fix is $3,205. 40 at the dealership. My 2007 Toyota Prius is valued between $2k to $4k. The repair would cost more than simply buying another Prius.

Check engine light came on with codes c 1256 & c 1300. Primary issue is brake actuator failure. Toyota is ignoring this known and repeated issue and it may lead to a dangerous/ deadly situation if brakes go out while driving.

2007 Toyota Prius brake actuator needs replaced. Abs, parking brake, vsc light came on 2 weeks ago when driving down a highway.

Failing brake actuator assembly. This is known issue by Toyota and they issued a brief warranty repair program, but have since stopped and refuse to fix the issue or provide assistance.

There is a known, (by Toyota), issue with the abs brake actuator in many Prius generations including the 2nd generation Prius that I own. My mechanic said it would cost @$3000 to fix. This as I said is and has been a known issue with these cars that affects the abs braking and puts myself, my family and any one on the road near me in danger. Toyota was quietly replacing these under an unadvertised, extended warranty program. Mine is out of this so called warranty period but if this was a known issue and was corrected at no cost due to the fact Toyota knew there was an issue why was there never a recall on the affected models all with this same problem? I feel that this dangerous problem should be corrected by Toyota at no cost to the owners of their dangerous affected vehicles.

Brake actuator system (abs) needs to be replaced with only 133k miles on my 2007 Prius. I heard a sound and had a Toyota service center check for any issues. They told me it was the abs system that needed to be replaced at a cost of $5k. The repair costs are greater than the car value. Toyota knows about this year, make, and model issue. I contacted Toyota corporate about this this week and learned there was an extended warranty for this specific issue on my car. They refuse to honor the extended abs system warranty even though I'm under 150k miles per the warranty. They told me a letter was sent to me about replacing it at no cost in 2017. I never received the letter nor did the Toyota service center I used at the time tell me about the issue. Additional info: I am not driving the car since the dash lights have come on - red triangle, check engine, vsc and (!) symbol - with a circle inside the (). Noise checked at Toyota dealer service center and confirmed it's the brake actuator system no inspection by the manufacturer, police, insurance rep, or others the sound came first when pressing the brake pedal and then the lights came on after taking to the service center.

Unknown I had just financed the vehicle 2-3 days prior.

Due to water infiltration from a poorly manufactured hatchback, water is able to get inside the "supply assy, brake control power" module in the trunk of the second generation Prius. This part ultimately shorts out and fails causing a loss of regenerative braking and a "brake warning light". Toyota seems to be aware of the problem as a replacement module is now sold in a "water proof sheet" (see attached). Toyota has also moved this module to a different location (away from the rear wall of the Prius) in other hybrid vehicles (such as in the camry where it has been moved forward). I wonder if the hybrid batteries in the Prius also fail due to water infiltration in the rear sections of these cars.

Toyota has admitted that their brake actuator assembly on their 2007 Prius fails and they will fix it for no charge but only if you complain. The brake actuator on my 2007 Prius is now failing and the braking system has become unreliable and unsafe. Toyota should replace my failing brake actuator with a new unit for no cost because this is a safety issue. I refuse to pay $3000 out of my own pocket to repair an item which has a long history of failing.

The abs actuator failed which caused the breaks to act up. Also casue warning lights. And noise from the pump. It also can casue the hybrid battery to fail because it can't charge right.

Abs vsc brake light on.

When turning car on the car beeps loudly for 10-15 seconds. The brakes will randomly lock up. They do not always work properly on hills.

Under hard braking (over 50% of the pedal) the front passenger wheel applies all the force to stop the car to that one tire causing it to lose traction and skid. Brakes are insufficient to properly stop the vehicle and no warning lights are illuminated on the dash. Actually more than half of the time the whole dash does nothing, no mph, no gas gauge, nothing but a blacked out information less panel. Then to top it off the car only has one headlight bc it blows what ever headlight I put into the ballast. 3 of the most common failures for a 2007 and my Prius has a grand slam assortment of serious potential life threatening problems that should have been repaired (never should have been assembled with) by Toyota. Minor wreck when attempting to stop the car under not driving conditions. Thankfully no one was hurt and only had to replace the front hood, bumper and radiator and support but have deemed the car as not road worthy and unfit for any driving conditions.

Brake actuator re. VIN: jtdkb20u973263792 on 4/13/21 my Toyota Prius '07 was diagnosed by Toyota of hollywood of a bad abs actuator that needs to be replaced. The fact of the matter is that about 28 months before that on 2/14/19 the actuator assembly was replaced by Toyota of north miami after being diagnosed first by Toyota of hollywood. The reason I choose to do the job in north miami is because it was less costly. My question is how can a genuine Toyota part fail in just 28 months. ? many Prius owners have been experiencing this safety issue since 2018. The warranty enhancement program ended before the fact in 2017. And there seem to be a misprint because how can the secondary coverage end on the same date as the primary coverage? (2017) when you use the date of first use of a 2007 Prius. Toyota needs to do another recall for this safety problem.

Brake actuator pump is a known issue on this generation Prius and Toyota has stop offering a warranty before I even got the vehicle.

My wife and I picked up our 3 little boys from school on our way home as we got on the highway we heard this loud long beep sound and immediately after that my brakes will not work so I began push down on the brake pedal many times and finally by the grace of god I was able to stop. We had the car towed to have it looked at and the mechanic concluded it is an abs/actuator problem which Toyota is very much aware of. The mechanic advised me to contact Toyota to fix it free because it is costly. I contacted Toyota about the situation and they just didn't care. Now I have no car because its unsafe to drive and I don't have the money to fix it. This was a life threatening situation for me and my family had it not been god we would have lost our precious lives.

My husband and I recently purchased a used 2007 Toyota Prius or are 17 year old daughter and since purchasing vehicle a little over a month ago she has already had four or more instances of her car dying and making her lose all control in the middle of the road. The car goes into neutral on its own and will not go back into drive or any other gear the car becomes immobile with no ability even steer off the side of the road or shut the car off or put it in park all dashboard lights come on brakes become glowing red hot and severe issues with lighting and moisture.

Brakes stopped working while in motion. Deemed unsafe and not to be driven. No pressure in brakes. Brake actuator has gone bad. $1700 part to fix plus labor.

Was driving on the highway on my way back to hilo from kona driving the speed limit on my 2007 Prius and out of nowhere I lost breaks for a time and it was a terrifying exp and I m happy I m still alive. Breaks came back with warning signs on dashboard that there is a failure in the break system, abs and other. Called hilo Toyota deal more than 5 times and each time I give them the VIN number they hangup on me in a rude way without giving any explanation why they are cutting the call. From there website I managed to start a txt message and asked for appointment to see what's wrong and paid 170$ and the result where that my break system have a recall on it and my car is at 118 000 miles so the recall expired in 2017 and they asked me 3500$ to fix the break system involved in the recall. After managing to call Toyota main office they started a case for this problem and on Monday they will give a final answer if they will change the failing recall break system or not. Also I managed to contact Toyota honolulu and I knew from them that Toyota hawaii is a different entity from Toyota mainland and that the safety recalls never expired and they should change the break system involved in the report no questions asked. Here I am reporting this to NHTSA as Toyota is gambling with people lives who still driving Prius which might lose breaks at any time and might endup in death result. I hope NHTSA will do the right thing and ask Toyota to change all those defected break system from manufactures before more american families dies from break failure which where never changed because the dealer prefer profit on safety of the people.

The abs brake actuator assembly is failing on my 2007 Toyota Prius, creating unpredictable and dangerous braking. It is a $3,000 replacement that, up until the end of 2017, Toyota was replacing at no charge, but no longer, under a warranty enhancement program, zg1, acknowledging that this part is defective. I went on line and discovered that this is a very common problem for 2007 Toyotas. This should not be just a voluntary "warranty enhancement," but a mandatory recall to force Toyota to fix this dangerous defect. This device runs almost constantly when it shouldn't, creates a drag on the car that has cut mpg in half, is probably wearing out the brakes prematurely, and causes dangerously slow acceleration from a stop that has resulted in some near accidents. I presume the abs function would not work when called upon. The repair cost is about half the retail value of the car, and it seems unfair that just because this showed up after their program ended, I have to foot the entire bill, or junk a car that is otherwise in perfect shape. There are 150k miles on the car, low for a Toyota of this age. I have attached the Toyota zg1 letter that I found on line. Please consider an immediate recall on this brake actuator assembly and make Toyota fix it for everyone.

Car rolls away when placed in park and ignition off. Noticed multiple times. Video as well. Vehicle was parked, ignition off and key are out. I locked and car, came back to load it and leaned against the car. The cr just started to roll down the street. I recorded video. Then I turned on the car, the parking brake engages properly.

If I drive on the expressway or around town and I'm driving a half hour sometimes less my car makes a loud buzzing noise and my instrument panel the hazard lights go on and I lose my brakes. This was very scary. Thank goodness I wasn't going to fast toward the light and didn't hit anyone. I'm scared to drive the car because it does this all the time if I'm driving for a period of time 1/2 hour or more. My vehicle was on city street and on highway. I was in motion. On the highway 70mph and on city streets 35/40 mph.

It had rained outside. When attempting to brake my car slid and would not stop. The brakes were hard to push and slid as if it was on ice. When trying to park the car it stopped suddenly as if I hit a wall.

Defective brake actuator assembly assembly.

Front wheels loose all traction on icy patch! traveling north on an old paved country road with a moderate crown and narrow lanes, I came upon a modest bluff that was just abrupt enough to keep me from seeing the road surface on the other side. Within 50' of the other side was blowing snow, some sticking and turning into ice. Air temp. 27 degrees. Don't know the surface temp, and it was sunny, nice. This patch was 500' or so and prompted me to remove my foot from accelerator. I was approaching 50 mph, not fast for this road and was in no hurry. Within the time of a breath, my front end blew smoothly toward the ditch and me and the Prius came to rest within 30' or so. Now this light to moderate cross wind took control of the front of the car, 'not the back'. The point being, rear wheels are free spinning, while front wheels have a rather aggressive breaking effect. Mind you, never considered touching the 'breaks'. In addition, I've learned that driving on snow covered town streets, that it is best to pop the car into neutral when approaching an intersection and applying the service brakes, this action would prevent the car slipping or sliding at all. (3 mo. Old michelin defender tires) not dedicated snow tires, but in my experience, very good. This town I live in has very steep grades, I'm able to negotiate all of it coming and going. I believe this incident (state farm claim #26-8025-x22) was caused by the overly aggressive regenerative breaking action when removing ones foot from the accelerator. Additionally, I would like point out that a hour earlier while driving to my destination, I'd driven over many drifting patches at varying speeds from 50 to 70 mph with a stiffer cross wind. However I could see them far in advance. After a lengthy go-a-round with Toyota over the phone, the response was, they will take no action on this car or in the future models.

First issue is with the rear latch being useless sometimes depending on the weather as the molding is all melted and access to the trunk being impossible. Second and most important I've noticed the braking on this car is very very suspect. Purchased this vehicle around 6 months ago from westbury Toyota and I've learned I need to apply my brakes at least a good 50 to 100 feet before the vehicle in front of me. Couple months ago the car in front of me braked so sudden that I also hit my brakes, the abs sign flashed as if it "was" working but the car just kept going, I ended up pressing the brake all the way to the floor and still no result. If I hadn't kept my distance I would've definitely ended up in that cars trunk. I can say from all my experience as a driver and all the cars I've owned this car has the worst braking system in the history of motor vehicles. Feels like braking a 747 plane. Extremely dangerous braking.

I have a Toyota Prius 2007, 283950 miles , safety recall zg1 ended on dec2017. The symptoms on this recall is not contstant before in my car, but now it stays on all the time . The brake actuator is making a lot of noise, I'm afraid it's going to fail on me when I needed it the most . Can you recommend Toyota to extend it some more ?.

The dashboard don't work sometimes, sometimes tha break light turns on and the breaks stop working it change it self to neutral and the power steering w. Get really hard. . All this hapens when the car is in motion on city streets.

For a months the car im driving has become more and more dangerous from steering to speed ,braking and drastic wobbling of entire car ive taken pictures and video its unbelievable and outrageous.

Breaking noise behind driver dashboard similiar to whirring or motor sound, comes on wether the brakes are pressed or not driving or stationary. . . Very bothersome, breaks also have bark sound at times when pressed down. Went to dealer and was dismissed as it being normal, called Toyota and they are unwilling to work on a repair. Please advise.

Squealing brake actuator. Occurs when car is stopped, in gear, brake pedal pushed down. This is an indicator actuator is failing, causing complete loss of brakes.

The brakes on this car sometimes quit working for a second when braking over bumps.

The brakes did not respond while I was driving on the freeway at 65 mph, and the car started making a long sustained high-pitched electronic beep. The lights for the parking brake, abs, and another light I'm unfamiliar with were on. When I pumped on the brakes, they felt unresponsive. I tried again but keeping down on the brake and it was very slow to respond. I managed to get off the freeway. At slower speeds I was able to get the brakes to work, but slowing down even from less than 20 mph took several yards. I called Toyota and they said it was a known issue with the brake actuator assembly, but the warranty expired in December 2017. As the owner of the car, I was never notified about this known issue, and not told about the warranty, even though I had been taking my car to the Toyota dealer for scheduled service. The part itself is over $2000, before labor, which I cannot afford. So I can no longer drive the car because I cannot afford the repairs. And I nearly died driving with a known safety issue that I believe should have warranted a full safety recall.

It was a scary situation on 08/08/2018, my �07 Toyota Prius 2 failed to stop when I applied the brake to stop and park instead it accelerated. Driving through the parking lot of seafood city in cerritos, CA, looking for an open spot, I maintained pressure on the brake pedal to keep a safe speed. Approaching an open spot, I continued to keep pressing the brake while entering the space. As I was straightening my steering wheel and applying a harder brake to stop, I felt the car accelerate forward, causing my instinctive reaction to apply even more braking pressure on the pedal. The car continued forward uncontrollably, jumping the curb of an island, hitting and knocking over a palm tree (approximately 15� tall) onto a parked vehicle (car #2) to the immediate left of the vehicle directly in front of me (car #1). My vehicle drove up the tree and came to a short rest on top of the hood of car #1, where my foot was on the brake the whole time. Immediately after stopping, and realizing that I was still applying a hard brake, trying to gain control of my vehicle, the vehicle began rolling backwards down the tree and off of the hood of car #1. The car didn't stop rolling backward despite my foot was pressing hard on the brake. It was the cousin of the owner of car #2 who reached and pressed the stop where that's the only time my car stopped rolling and came to a complete stop. It was the worst feeling as I was not in control of the car as the brake didn't work. I was so shaken, me and my husband were discussing what to do. We immediate called the dealership and told them what happened, they gave us the corporate instead. The Toyota corporate office was indormed but we believe that Toyota is not taking this case seriously. A police report was taken by officer clayton of cerritos sherriff station ref. #918-03548-2318-483.

Brake, vcs,abs and (!) lights came on. Other Prius owners said Prius was covered under warranty for this until Dec 31 2017. Abs module went bad. Lights came on when started car. Never got notice that this was covered, others say NHTSA should make Toyota extend coverage.
