   The brake booster assembly failed, as many of these models had before. A bunch of codes went off as I was driving and the brakes did not function properly. Toyota had an extended warranty for this which they discontinued last year and they would extend no good will towards the $4,000 repair

   Emergency Brake, Traction and ABS warning came on and stayed on in addition to a five-second interval cycling on of a motor sound under the hood. O'Reilly Auto Parts and then Toyota dealership confirmed the same code that indicated brake booster assembly needs replacing (C1391) **This is a "known issue" but not yet a recall. Toyota did extend the part warranty to 10 years or 150,000 miles - my vehicle has only gone 85,500 and unfortunately is eight months into the 10th year and Toyota is refusing to cover any portion of the repair. I would like to be part of the effort to have this formally declared a recall because I got the quote today to replace the brake booster assembly and it's going to cost half the value of the vehicle! $4000 is the low estimate Bighorn Toyota gave me to do the repair/replacement. Thank you for your help!

   I started hearing the whirring sound from the brake booster that normally only comes on at startup almost constantly, about every 15 seconds. Along with this, a puffing sound and a pulsing from the brake pedal when stopped with the car on, such as at a traffic light. Also, when coming to a stop there would be a shudder from the brakes. After about a month I was driving when 3 separate warning lights lit up on the dashboard and the next time I braked the pedal felt very different than normal, very mushy, and the car seemed to not stop as well. I consulted a repair shop and they told me it’s a common problem with this model: brake booster/actuator failure resulting in a loss of the ABS system. They quoted me over $2000 to make the repair. Internet research confirmed that this is a common problem that Toyota is aware of but refuses to acknowledge as something to be recalled, despite the huge safety risk associated with it. This on a car with only 85,000 miles.

   My Prius V has slow acceleration and the RPMs seem to go unusually high on acceleration. This makes it dangerous to pull out from a stop sign, etc. in certain situations that would be fine in another car of the same make and model. And recently it has started to throttle up when taking my foot off the gas and even when pressing on the brake. This happens intermittently and randomly. Fortunately no accidents have occurred yet and I'm trying to get the problems resolved with Toyota, but the dealer says it will be hard for them to diagnose when the problem is not occurring and there are no warning lights. Less than 60,000 miles on it.

    TRAVELING AT APPROXIMATELY 25 MPH IN A NEIGHBORHOOD, I HAD JUST TURNED INTO A DIAGONAL PARKING SPACE IN A CUL-DE-SAC AT ABOUT 10AM AND THE CAR SUDDENLY ACCELERATED FORWARD AND HIT A YELLOW IRON POST BEYOND THE FRONT OF THE PARKING SPACE. IT HAPPENED IN A MATTER OF 2-3 SECONDS AND I COULDN'T STOP THE CAR BY BRAKING. THE POST STOPPED THE CAR AND CAUSED EXTENSIVE DAMAGE TO THE CAR. IT WAS EXTREMELY PERPLEXING AND I STILL DON'T THINK IT WAS CAUSED BY MY ACTIONS DUE TO THE SUDDEN ACCELERATION. I NO LONGER HAVE PHOTOS OF THE DAMAGE. I CONTACTED MY INSURANCE CARRIER AND MY RATES INCREASED SIGNIFICANTLY BUT I STILL FEEL STRONGLY THAT I DID NOT CAUSE THE ACCIDENT. I HAD BEEN DRIVING AT 20MPH THROUGH THE NEIGHBORHOOD PRIOR TO PARKING. REPAIRS TOTALED ABOUT $2400.00.

BEFORE WE COULD FIND A SPOT AT THE SIDE OF THE ROAD THE ENGINE SHUT OFF AND WOULDN'T TURN BACK ON, BLOCKING TRAFFIC. VEHICLE TOWED TO LOCAL TOYOTA DEALER. ENGINE TURNED ON AT DEALERSHIP. DEALER RAN DIAGNOSTIC TESTS AND SAID NOTHING WAS WRONG WITH CAR. SENT US HOME SAYING CAR WAS FINE. NOVEMBER 24, 2020 RECEIVED NOTICE FROM TOYOTA ABOUT CUSTOMER SUPPORT PROGRAM FOR FAILURE OF "INTELLIGENT POWER MODULE (IPM) LOCATED INSIDE THE INVERTER ASSEMBLY OF THE HYBRID SYSTEM". CONDITION DESCRIBED AS "HYBRID SYSTEM WARNING" SHOWING ON INSTRUMENT PANEL AND VEHICLE GOING INTO "FAIL-SAFE DRIVING MODE". CALLED PHONE NUMBER ON THE NOTICE AND WAS TOLD THE PROBLEM WE HAD WITH THE CAR WAS THE CONDITION DESCRIBED IN NOTICE, BUT NOTHING COULD BE DONE UNTIL IT FAILS AGAIN AND THE DIAGNOSTIC TESTS ARE POSITIVE. IF THEY KNOW THIS IS A SAFETY PROBLEM, AND IT ALREADY HAPPENED ONCE IN OUR CAR, THEY SHOULD REPLACE THE FAULTY PARTS, NOT WAIT FOR US TO GET INTO A WRECK ON THE FREEWAY.

EXPRESSED MY CONCERNS AT PETERSON TOYOTA DEALER LOCALLY, BUT THE TECHNICIAN STATED THAT "IT'S NORMAL", COULD BE THE BRAKE HYDRAULIC BOOSTER SYSTEM? THE ISSUES STILL CONTINUE AS OF TODAY.

    THIS IS AN OCCASIONAL AND INTERMITTENT ISSUE. AT 35 TO 45 MPH, TRAVELING STRAIGHT, ON CITY AVENUES AND BOULEVARDS. WHEN BRAKING IN AN URGENT FSHION (NOT PANICK AND NOT EASY) THE BRAKE PEDDAL IS SOFT AND TRAVELS SIGNIFICANTLY FURTHER THAN USUAL BEFORE THE CARS BREAKING SYSTEM TAKES EFFECT. THIS WAS ON DRY ROADS AND ABOVE FREEZING TEMPERATURES. WE HAVE NOT EXPERIENCED ANY ACCIDENTS DUE TO THIS BUT THERE HAVE BEEN MOMENTS OF NEAR PANICK PRIOR TO THE BRAKES WORKING AS EXPECTED. AS A SEPARATE BRAKE ISSUE, ON TWO OCCASIONS WHEN PANICK BRAKING FROM APEEDS OVER 50 MPH, TRAVELING STRAIGHT, ON FREEWAYS THE BRAKES HAVE LOCKED AND THE CAR HAS SKIDDED. THIS WAS ON DRY ROADS DURING DAYLIGHT HOURS, DRY ROADS AND ABOVE FREEZING TEMPERATURES. THIS VEHICLE HAS ANTILOCK BRAKING SYSTEM. THE LOCAL TOYOTA DEALER WAS ADVISED OF THIS LOCKING ISSUE AND REPORTED THEY FOUND NO ISSUE. WE HAVE OUR BRAKES INSPECTED BY A LOCAL TOYOTA DEALRE AT MANUFACTURER RECOMMENDED INTERVALS AND HAVE BEEN GIVEN A 'GREEN' RATING FOR PAD THICKNESS. THE ABOVE EVENTS STARTED LATE IN THE FIRST YEAR OF OWNERSHIP AND WE ARE THE FIRST OWNERS OF THIS VEHICLE. I AMA RETIRED ENGINEER WITH A FAIR BACKGROUND WITH PERFORMANCE DRIVING ON CLOSED CIRCUITS. I HAVE A SOLID UNDERSTANDING OF PROPER BRAKE PERFORMANCE. I FOND THE ABOVE EXPERIENCES DISCONCERTING AND OF CONCERN. THE BELOW DATE OF OCCURRENCE IS FOR THE LATEST SLOW BRAKE RESPONSE, NOT THE LOCKING UP.

    2015 TOYOTA PRIUS V: THIS CAR HAS A BRAKE SYSTEM ACCUMULATOR THAT ACTIVATES AFTER THE CAR HAS SAT FOR A SUFFICIENTLY LONG TIME (OVERNIGHT, DURING THE WORKDAY, ETC). WHEN YOU OPEN THE DRIVER SIDE DOOR, THE ACCUMULATOR ACTIVATES AND PRESSURIZES THE BRAKE SYSTEM. HOWEVER, WHEN USING THE BRAKES WHILE DRIVING FOR THE FIRST TIME AFTER THE ACCUMULATOR ACTIVATES, THE BRAKES ARE WAY TOO SOFT/SPONGY - SO SOFT THAT IT FEELS LIKE THE CAR WILL NOT STOP AND THE STOPPING DISTANCE IS LENGTHENED, SOMETIMES MORE THAN DOUBLED. MY LOCAL DEALER CLAIMS THEY HAVE TO BE ABLE TO REPRODUCE THE PROBLEM TO FIX IT. I HAVE HAD OTHER MODEL PRIUSES WHERE THEY HAVE SAID THE SAME THING, YET THE PROBLEM TURNED OUT TO BE A SYSTEMIC ISSUE IN A CERTAIN PRIUS MODEL. I FEAR THAT THIS IS ANOTHER PERVASIVE BRAKE ISSUE THAT TOYOTA IS TRYING TO HIDE.
