2013 Toyota Prius problems

“On XXX, at approximately 152,570 miles, the brake, ABS, and traction-control warning lights illuminated at the same time on my 2013 Toyota Prius. The brakes felt spongy, and I heard a recurring buzzing sound approximately every 3 seconds. Because of the change in brake-pedal feel and concerns about braking safety, I stopped using the vehicle. I reported the problem to Longo Toyota in [XXX], which directed me to Toyota customer support. The vehicle was subsequently diagnosed with trouble code C1391, “Internal Leak in Accumulator.” I contacted the dealership and Toyota customer support about Customer Support Program ZJB, which addressed code C1391 brake booster and brake booster pump failures. Toyota denied coverage because the failure occurred outside the program’s time and mileage limits. The symptoms began only 2,570 miles beyond the 150,000-mile limit. My primary concern is **safety**, not simply the expiration of coverage. The vehicle developed spongy brakes, multiple warning lights, and frequent buzzing. The diagnosis appears consistent with the type of brake-system failure Toyota previously addressed through ZJB. I request that NHTSA investigate whether…”

“The contact owns a 2013 Toyota Prius. The contact stated that while driving and pulling into a parking lot, there was a burning odor coming from the vehicle. The contact exited the vehicle but saw no fault with the vehicle. The contact was then notified by another person that the vehicle had caught on fire. The fire department extinguished the fire and informed the contact that the windshield washer fluid reservoir was melted in half with burned wires nearby. The fire department stated that the fire was caused by the electrical wiring on the passenger’s side near the coolant reservoir under the hood. The vehicle was not destroyed and was towed back to the residence. A bystander who helped extinguish the fire had sustained a burn to the left arm. Medical attention was administered at the scene. Additionally, the contact stated that the passenger’s side rear tire was losing air pressure every morning with the TPMS warning light illuminated. The manufacturer was notified of the failure. The failure mileage was 138,932.”

“Crack in the Engine. I had been following the recommended Maintenance schedule, but I suddenly had issues where the engine would stall/stutter on activation (switching from electric to motor operation). The check engine light came on, and I immediately took it to the dealer who replaced the battery and spark plugs saying that was the issue. That solution did not even last a month, as I had sometimes severe shaking in the engine along with the stutter. I again brought it to the dealership who told me that the actual problem was a cracked head gasket and that the vehicle was "mechanically totaled". I was lucky that I live close to the dealership and worry what would have happened if I had to drive on it further.”

“The contact owns a 2013 Toyota Prius. The contact stated that while driving 60 MPH, the ABS warning light illuminated.

The contact’s chest struck the steering wheel, causing bruising and chest pain. The contact was managing the pain with analgesics.

The manufacturer was contacted and was made aware of the failure. The failure mileage was approximately 140,000.”

“The brake actuator keeps buzzing every 3 seconds or so the entire time the car is on and even after I turn the car off and get out. The brakes make a wierd burping noise and the pedal depresses with each noise if I am stopped at a red light or stop sign with my foot on the brakes. All of the brake, abs, and traction control lights lit up. The regenerative braking is no longer working.”
