In September 2022, my car, a 2012 Toyota Prius V with 79, 056 miles, began making noises in the engine area and the brakes became loose, meaning it took more pressure on the brake pedal to engage the brakes. In November 2022 the following warning lamps on the dashboard came on: Master Warning Light, Brake System Warning Light and Warning Buzzer, Brake System Warning Light, ABS Warning Light and SLIP Indicator. I took it to the Toyota Dealership near me: Lipton Toyota in Ft. Lauderdale, FL, and they diagnosed car with the trouble code of C1391-Abnormal Leak of Accumulator, Internal ABS Actuator Failure. To fix this problem, Lipton Toyota will charge $3124.29 for the repair. Toyota Motor Sales, U.S.A., Inc. issued a customer support program notification that would cover this repair if the malfunctions happened before coverage ended. Primary Coverage was applicable until December 31, 2021 with no year/mileage limitation. Secondary Coverage was applicable for 10 years from the vehicle's date of first use or 150,000 whichever occurs first. Date of first use on my Prius V was 03/01/2012 and my mileage is 79K. So as you can see, I am just out of the coverage window. My private mechanic and myself have appealed our case to Toyota that this problem should be a recall with no limits on coverage. (Toyota Motor Sales, U.S.A., Inc. - case reference # 230206000678) I believe that if I had driven my car more, (which was not done because of the Pandemic 2020-2021) this issue would have come up before the cut off date for repair coverage. I also believe that this problem with the Brake Booster and Brake Booster Pump Assemblies on certain 2012-2014 model year Prius V vehicles should be a recall.

Faulty brake and ECU assembly failure. A safety issue when driving. Was told by mechanic NOT to drive car as it could suddenly stop. Took car in 9/11/15 for software update for motor generator ECU and power management ECU as recall letter suggested. This is apparently common and needs to be corrected without cost to driver.

Bought the car from a dealership in january 2022 with 158,000 miles and heard buzzing noise that I was told was normal with hybrid cars.no codes showing on car and passed dealer inspection.Driving down a highway and heading to a stop brakes are hard to mash and caused skidding. No brake lights or abs lights are on. Couple days later brake lights and traction lights come on and then went back off. Take to Tires Plus and I am told I have to schedule appointment with toyota dealer as they do not have the software to diagnose. Take to toyota dealership to see codes 1391c for brake system. After searching issue there was a recall/customer warranty extension for replacement of this part for 150,000 miles /march 19,2022 whichever comes first. This did not show up on a report for dealer to inspect before selling vehicle and causes a huge safety concern to people that did not own this car before 150,000 miles. If a less experienced driver would not have known to reduce brake pressure applied it could have slid and caused collision or if brakes would have been needed during an emergency situation. Car is now sitting at toyota dealership and advised not to drive as brake pressure was lowered while being diagnosed. After talking with toyota they cannot provide assistance due to car being slightly over the 150,000 mile mark. Also if the brake pedal is mashed for an extended period of time the dash lights for brake system and traction control go off and will not come back on until it is driven for awhile

Toyota prius v 2012 lost power as I was driving out of the parking lot. I had to make emergency stop on the side of the road because inverter/electric motor failed. Mechanic ran computer test and found that problem codes indeed pointed to failure of inverter.I called local dealer mccord toyota and was told my car does not fall to extended warranty of inverter and did not offer any help. Same day I called toyota customer care at 1‑800‑331‑4331 and they told me that my car does not fall under inverter warranty based on my VIN number, and gave me case number 2005072419. I was able to call my insurance company to arrange towing from my location to repair shop. Repair shop completed work and vehicle is now in operable condition. I feel lucky that I was not on freeway and did not have my children with me when it happened.

My 2012 prius v started showing the warning lights for brakes, ABS, anti-skid and engine lights. This happened while driving on a regular road. Brakes still work but feel spongy. Scanned for codes and it says c1391 which requires replacing all the main brake components. The cost is over $3000 because so many parts involved. There's seems to have been a recall for other models of prius but the 'v' not included. Many v owners have experienced this problem. All the parts shown in the attached picture need to be replace cause toyota doesn't know or can't figure out where the problem is. Car only has 68,000 miles on it
