Toyota Prius 2010 started experiencing braking issues in January 17, 2020. Car was taken to the dealer three times with miss diagnosis. In March dealer diagnosed issue most likely a brake booster and pump assembly which was a known issue with 2010 Prius. Toyota identified the issue in a previous quality campaign but only repaired if brakes fully failed. Brake failure is what it took to have your car repaired?

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 have lost all regenerative braking. The ABS, traction control, and service lights are all illuminated continually. It has become difficult to stop and the hybrid battery is depleting at a rapid rate with very slow recharging.

On Tuesday, February 23, our braking system failed on our Toyota Prius while driving on a side road after months of continuing weakness in the brake pedal and "lurching" when braking over potholes. The brake system lost hydraulic pressure. Upon inspection by an ase-certifie mechanic, they determined the brake booster assembly had likely failed, but recommended sending to a Toyota dealership. They confirmed the vehicle was unfit to drive. The vehicle was sent to a Toyota dealer. The dealer confirmed the break booster assembly/actuator had failed. The dealer advised the brake booster had previously been under a Toyota "customer service campaign, " but that the "warranty" campaign had expired. However, he advised Toyota brand engagement center has often assisted customers when they're just outside the warranty period. When contacting Toyota, they stated this vehicle was never under recall and was not eligible, but then said they sent information on a Toyota safety campaign. Upon research, we continued to confirm that the diagnosis was tied to recall D0H from July 2013. We've also reviewed our vehicle history, and the brake pump assembly was never replaced despite being inspected consistently by Toyota dealers since 2013 and under recall. Toyota has declined to cover the cost of the replacement for the brake pump assembly. The cost of repair is nearly the same as the current value of the vehicle. Toyota brand engagement center has declined to provide this information in writing, would not provide a name, and otherwise acted completely sketchy - for lack of a better word - any time we tried to clarify the repair was clearly tied to the June 2013 recall. We were very, very fortunate the brakes failed on a side street near our home, not on a highway or other high-risk area. We would like Toyota to honor the recall, extend it for other customers, and cover the cost of repair.

Went over bump at railroad crossing and ABS, brake, slip warning lights came on and regenerative braking stopped working. Car was harder to stop. Took to dealer and car was diagnosed with this work needed: Replace booster and booster pump assy and reflash (failed booster, booster pump) fail $3,259.84 car is beyond warranty fix dates though all these cars were recalled in Canada and a class action suit is ongoing in Ohio over this issue. Why won't the ntsb follow Canada's lead and get these failing brake systems fixed before something serious happens?

My car's ABS, traction, and brake lights are on. I took it to two shops and they both said my car was recalled and to have the dealership fix it. The recall is on the breaks. The brake pedal is also not fully working, there is an abnormal leak of brake fluid pressure. Both auto service places said to demand for the dealership to take car of this because there is a class action lawsuit going on for this car with this exact problem.

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 casing of the brake actuator is cracking. The brake actuator apparently is an underlying problem that Toyota does not want to take responsibility for and fix.

Toyota brake booster pump has failed due to manufacturing defects, which affected the stopping of the vehicle. Toyota has issued recall for this problem but only for latest models (2019 and later). I've called to Toyota and they refused to address this problem. I looked up on internet and found this is a wide spread problem experienced by many owners of priuses. Toyota must issue the recall for all the vehicles affected, not the latest ones only.

I am having an issue with my brake actuator/brake booster. This is a known issue and Toyota is refusing to help with the issue. The ABS, brake, and traction control light are on and regen braking is not working. They are supposed to cover this based on bulletin zjb but absolutely refuse any help.

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

Upon starting the car, the ABS, brake and traction control lights all came on. Checked brake fluid and it was at max level. Took to dealer and showed code 1391 which showed the brake booster and booster pump assemblies need replacing. It's a known problem with Toyota. A voluntary recall was issued for our 2010, but my specific model wasn't included and recall expired in 11/19 or 150K miles. I'm at 150,992. There is active recall for same issue for 2011-2015 models. It's a known safety issue and they refuse to fix it. It's a $3K job to repair for a car that is worth about double that. When this warning comes up, your braking system is not reliable. Had this happened while driving, an accident could have occurred. Toyota knowing this is a safety issue needs to correct it on all models that show this warning, not just select models.

I went to the dealer as I was told after opening a case with Toyota, , however the solution was not resolved to my satisfaction. Basically. Safety parts were replaced from a recall on 08/2013. A few years later I got another Toyota notification that if I had these brake booster related failures/lights to bring it in, I would have even if I had the lights without the notification. The other day I had the failure related to the defective parts installed on 08/2013. So somewhere between 08/2013 and when Toyota notified me about the lights or the still existing defect, that there was a defect going to happen but did not know when and today I had the failure. I believed that since I had the original replacement brake safety parts replaced that I was driving a safe Prius. I feel the second repair for the same parts should be covered since when they notified me they knew there was a defect and chose not to absorb the cost of this remedy.
