2012 Toyota Prius V owner complaints

The power assist braking system failed while I was driving in the rain. I was approaching a stoplight and I had to push down a lot harder and farther than I typically have to in order to stop. Luckily I was not going that fast and there were no cars ahead of me, but I stopped beyond where I had intended at a busy intersection. No warning lamps or messages had been illuminated prior to this happening. After the failure, the Brake system, ABS, and SLIP indicator lights were on and remained on when the car was restarted. An independent service center used a scan tool and found code C1391 stored in memory, indicating that the brake booster is unable to hold pressure due to an internal leak. The vehicle has not yet been inspected by the manufacturer, police or insurance, but can be available up

I bought this car over a week ago for a good price, performed fine until I’m driving it home on the interstate and some abs/brake lights came on the dash. I enter my city and notice the brakes aren’t performing as tight as they were during the test drive. A few days later I take it to a local dealership to get it looked at. The brake actuator and pump had gone bad, causing this issue. It cost almost $5,000 to fix there, I couldn’t afford it so I had to only pay the $185 for the diagnostic. It’s an on and off thing, sometimes the lights go away and it brakes as it should, but most of the time the lights are on and the brakes don’t work as they should. I fear one day the brakes may eventually give out on me and cause an accident. I am available for inspection.

After 13 years and 112,000 the brake booster and brake booster pump went out on my car. Toyota extended the warranty to 10 years because of this issue. Now just outside of the 10 yr mark my car has this issue and Toyota will not cover it. This is a huge expense and also a major issue with this year and model of car.

I have a Prius v 2012, and the lights for abs turned on and when I checked on internet Toyota was repairing the part for 150k miles and 10 years but this is a safety feature my car is now at 149922, And while I was on road suddenly the signs came up and I the brakes were hard, and this is a problem for my safety and for others too since It doesn’t brake well

ABS, brake, and traction control lights, all illuminated at once on the dashboard. Inspection found DTC C1391 indicating the accumulator is leaking or failing to hold pressure correctly. We are advised that the braking system performance will decline, eventually failing. An very expensive repair is required and Toyota apparently has a shortage of the parts required. We cannot drive the vehicle given the potential of braking failure and cannot get it repaired in a timely manner for lack of Toyota parts.

The contact owns a 2012 Toyota Prius V. The contact stated that while driving at an undisclosed speed, the brake master cylinder was constantly cycling. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed or repaired. Most recently, while the vehicle was turned off, the brake master cylinder was cycling. The contact stated that while the keys were in his hands and standing several feet away from the vehicle, the brakes started cycling. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 140,000.

2012 prius v 68,000 miles on vehicle brake issues from the time car was purchased new from a Toyota dealer. History... When braking and going over rough surface or bump, the brakes would seem to momentarily disengage and then reengage after the surface smoothed. The car seemed to lunge or skip forward and take longer to stop. Alerted the dealership, they checked and said everything was fine. This has continued throughout my ownership of this vehicle. Recently during an emergency stopping action on a freeway, my prius was the 3rd car in a 3 car accident. The 1st car for some reason, slowed drastically,and was rear ended by the car in front of me. I felt I was at a good distance behind the car in front of me and I reacted and fully depressed the brakes and felt this car continue to r

8/2/22 My ABS light came on. Took the car to a dealer. They kept it for six weeks and returned it on 10/3/22. No charge and no explanation. 11/7/22 engine light came on. Took in to dealer, they returned it 11/17/22 indicated incorrect air/ fuel mixture. 10/9/23 Traveling 47 mph, came around a mountain and encountered stopped cars. Slammed on the brakes, car did not slow down, steering wheel locked to the right, car yawed to the right, and turned over, hit a curb and the car righted itself. 3 occupants, 2 injuries , 1 death. Researching the 2012 Toyota Prius, found many instances of a faulty ABS system, mimicking exactly my experience. I was never informed by Toyota or the local Toyota dealer.
