This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
ABS and break light lit while going 55 mph. Lost antilock break feature. Local port St lucie tire and break diagnosed bad master cylinder and nitrogen leak into break lines. Found recall on similar 2010 Prius' due to nitrogen leakage into break lines
All brake lights come on (brake, ABS and traction control) and power assist breaking stops working and brakes feel very weak. Brake actuator runs frequently when lights are not on. There are many complaints online and Toyota claimed they fixed this issue in 2009 and extended the warranty for 2009 and earlier, but the problem is clearly not fixed.
The contact owns a 2010 Toyota Prius. While the contact's wife was driving 35 mph, the ABS, traction control, and brake warning indicators illuminated. The driver had to apply extra pressure to the brake pedal to slow down the vehicle. The vehicle was taken to an independent mechanic who diagnosed that the brake booster and master cylinder failed and needed to be replaced. The vehicle was repaired. The dealer was not contacted. The manufacturer was made aware of the failure and stated that the vehicle was not within the VIN range. The approximate failure mileage was 95,000.
ABS light came on. Diag code: C1391. Abnormal leak in accumulator. This problem is similar to a recall on Prius 2010 for ABS brake issue. However, Toyota said that my Prius is not part of the recall. I would like to request Toyota to fix this problem for my Prius 2010 so that I can safely drive this car.

I change the brake booster twice and hace the same problem. My brake pedal loss of braking ability or slipping brakes and the warning brake, ABS and traction light permanently on, and no cruise control works at all
Brakes turned to mush - pedal went all the way to the floor with almost zero stopping power. Sounds like a similar recall from 2013 or so. Going 45 mph (speed limit) on a busy 4 lane hghway approaching stoplight and slowing traffic for red light at intersection of another 4 lane road. Brakes mostly unresponsive. Almost went through intersection and narrowly missed hitting a slowing car. Braking did not engage per usual activation position and pedal went to the floor instead. Car was just serviced a week ago for unrelated recall item. Car has been maintained diligently since new purchase in 2009, getting all recalls serviced promptly. Maybe the range of vins in the older recall was not wide enough?
When driving over bumpy or rough surfaces or pot holes, while applying the brakes, the brakes often seem to stop working. And the car seems to have a little boost forward. It happens wherever the road surface has bumpy areas on straightaways or curves. And mostly when applying light pressure to the break, like slowing for an upcoming turn. It has been happening since I got the car in 2013. I have taken it to a mechanic, but they couldn't find the problem. This has happened many times over last 3 1/2 years.
I am the original owner of a 2010 Prius. Within the first month, I contacted Toyota, complaining of the brakes, which were not consistently smooth. In general, the brakes work fine, but if I hit a bump or ditch, the brakes suddenly stop working for a split second, and the car feels like it is lurching forward, before the brakes suddenly start working again. Toyota service was never able to "reproduce" the problem, and eventually I gave up. A couple years ago, the car was recalled for this problem, and I brought the car in to be fixed. Unfortunately, the recall work has not remedied the problem. The brakes still seem to occasionally malfunction when the car drives over a rough patch. Toyota seems to believe the problem has been solved, but it has not be solved. There is no difference since the recall.
This afternoon, my wife was driving down a two lane, paved street at about 25 mph. The street has a slight decline and she began to apply the breaks to slow down slightly. Just a second or two later, she hit a small bump in the road and the car accelerated (while she had her foot on the break) for a fraction of a second. We didn't hear the sound of the engine revving. Thankfully, there were no other cars on the road at this time and there was time to press the break again. Based on looking around online, many people have reported similar issues (www.consumerreports.org/cro/news/2010/02/Toyota-adds-2010-Prius-braking-problem-to-the-list-recall-possible/index.htm).
When I am coming to a stop (braking normally) and hit a bump, the car surges slightly and the brakes become less responsive. It feels like I'm fighting the engine as it accelerates and I'm trying to brake against it. Releasing the brake and attempting again seems to be a solution, but I often don't have time before reaching the intersection I'm approaching. This consistently happens in two places in my daily commute with a slight buckle in the road approaching an intersection on city streets and county roads.
Driving down highway at posted speed limit (75mph), I tried to slow down due to traffic and noticed my cars ability to brake was severely compromised. I then noticed my cars brakes, ABS, master warning and vsc lights had came on. Given that my car has 103K miles on it, I figured it is time for a brake pad service. With the limited braking ability, I decided to make the short drive to the Toyota dealer for brake service. After the dealer inspected my car, a representative told me that it is not the brake pads that are causing the lights in your dash to go on but rather the brake booster. They advised me that it is not recommended that I drive the car anymore until the issue is remedied by replacing the brake booster at a cost of over 2K. I had to also incur the cost of a rental since the booster was not in stock and would take over the weekend to receive. I was taken aback by the total cost of the service but had no choice and proceed to get it repaired. Upon receiving my car a few days later, I drove to work and upon my return home, the issue repeated itself with all the lights on the dash lighting up and the cars braking ability was again compromised. Extremely irate, I drove directly to the dealer and upon inspecting the car they told me that it is now the accumulator that needs to be replaced. This time the dealer absorbed the cost of over 3K to replace it. I researched the internet for any known recalls and found the issue was being addressed by Toyota with a recall however my cars VIN was not part of it. It is my hopes that you make Toyota aware of the safety issue and initiate a recall on all 2010 Prius models and not just some. I would also like to get the cost I incurred with this safety issue reimbursed at some point.
ABS actuator with master cylinder assembly has internal leak. Assembly doesn't hold pressure and actuator motor continiously working in order to create the pressure. Due to this problem brakes are not operate as properly. It takes more strength to put on the pedal to stop vehicle. I also noticed that during emergency braking not all wheels were involved equally. Due to this problem braking distance significantly increased. I have 3 instrument cluster error lights turned on due to this problem: "brake", light with vehicle on sleepy road, and light with "!" sign. I found that there already was recall for same 2010 year Toyota Prius under tms-ntc-13178 of July 23, 2013, Toyota recall name D0H, but my vehicle is not covered. I kindly ask you to investigate if my car eligible to participate in this recall campaign, since seemsthat this car were assembled with same unreliable parts.
The brake actuator failed on our 2010 Prius III manufactured in October 2010. Toyota is covering problems with this same brake actuator for 2010 Prius manufactured between March 2009 and early October 2009. My VIN did not fall into that date range even though mine was manufactured in October 2009, so the brake defect should be extended to beyond the early October 2009 manufactured date. The symptoms to this problem were the brake, ABS and traction control warning lights came on, no regenerative braking and the braking distance increased.
The contact owns a 2010 Toyota Prius. While driving 20 mph, the braked pedal was depressed and failed to operate as intended. The contact stated that several warning indicators illuminated. The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that the brake booster pump failed and needed to be replaced. The vehicle was not repaired. The vehicle was not included in NHTSA campaign number: 13V235000 (service brakes). The manufacturer was notified of the failure. The approximate failure mileage was 100,000.
The brake booster pump assembly failed, which left me with no brakes and in a life-threatening situation. The vehicle was in motion and I narrowly avoided a bad accident on a city street.
ABS + breaks + tcs lights are on and my car's breaks are not working it was about to hit with next car but my speed was under 30 that's why I reached safely. I showed it to just break and they said it's required ECU update. It's a software problem in this model. I don't know how to update software. Is it possible if I get free update from Toyota dealership ?

My wife was driving on the highway when her brakes totally failed. She applied brake pressure as hard as she could, but it had not effect. Fortunately, since she was in the left lane of the interstate highway, she was able to coast to a stop in the left hand shoulder. Several red lights lit up on the dashboard, including the brake and ABS lights. I had the car towed to world Toyota dealership in atlanta. They said the brake master cylinder failed. I paid them to fix it. See attached work order from world Toyota.
