Had blown gasket repair last year (which was fixed by my local Toyota Dealership and all cost paid for by myself). Dealership acknowledged that there were known issues with failures due to clogged EGR's and out-dated manifolds. Was never recalled and did not know about the issue until after the incident. Wanted to report issues since it appears countless other have been in the same situation with gen 3 Prius. Toyota needs to be offering EGR cleanings and updated manifolds at no cost and reimbursing customer's for previous repairs.

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.

The contact owns a 2012 Toyota Prius V. The contact stated while driving 30 MPH, the vehicle stalled inadvertently. Several unknown warning lights were illuminated. Additionally, the brake pedal was depressed but failed to respond. The contact veered to the side of the road and intentionally struck the curb to stop the vehicle. The vehicle failed to restart. The contact stated that the vehicle later restarted and was driven to the dealer. The dealer diagnosed that the ABS actuator had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist because an unknown Toyota Courtesy Program issued for the failure had expired. The failure mileage was approximately 160,000.

My toyota prius v only has 121,153 miles on it and during a short drive to work where we never reached speeds over 50mphs our prius v overheated causing a blown head gasket and all sorts of combustion issues. The repairs were $3000. This is a 2nd family car which has always been maintained by expert, license auto mechanics. This should never happen on a car with such low milage! I have learned that this is a common issues with this toyota prius model and toyota should file a recall and fix the overheating issues.
