2015 TOYOTA PRIUS V Complaints

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!

Brake light + ABS + traction light came on and the brake became harder to control. I was driving in the rain and briefly lost control. Fortunately, no accident.

Brakes failing while driving in the rain. I was unable to use my brakes in the rain and headlights turned off while driving too. Took it to the dealer and they won't do anything unless lights are on on dashboard to read the code.

The contact owns a 2015 Toyota Prius V. The contact stated while driving at various speeds, there was an abnormal knocking sound coming from the engine compartment. The check engine warning light was illuminated. Additionally, the contact stated while driving at speeds under 65 MPH, the vehicle intermittently lost motive power. The vehicle was taken to an independent mechanic where it was diagnosed and DTC codes: P0300, P0302, P0303, and P0304 were retrieved. The contact was informed that several undisclosed parts needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 162,000.

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.

The contact owns a 2015 Toyota Prius V. The contact stated while driving at an undisclosed speed, a vehicle hit the front driver's side causing damages to the front driver's side door and undercarriage. The contact stated none of the air bags deployed. The contact stated ambulance did arrive at the scene where they took the contact to the hospital. The contact sustained injuries to their head due to the front side window shattering causing a laceration on the left eyelid and small facial fracture as well bruising and swelling of the left eye. The contact stated the other driver in the accident and passenger was taken to the hospital as well but the contact did not know if they were injured. A police report was filed. The vehicle was towed to the tow yard. The contact attempted to reach out to the local dealer but there was no response. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 76,000.

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.
