2014 TOYOTA PRIUS Complaints

BRAKES ARE NOT WOKING AT FULL SPECIFICATION DUE TO BRAKE ACCUMILATOR HAVING AN INTERNAL LEAK C1391

After I started my car and began driving away from a shopping center, I noticed that there were 3 static warning lights on the dashboard that had not been there before. They were the slip indicator light, the brake light, and the ABS light. I also heard a short, repeating buzzing sound coming from the front of the car that I had never heard before. As I was driving, the brake suddenly felt loose. Luckily, this happened as I was pulling out of a shopping center parking lot, so I was able to pull over to the side of the road instead of getting on the highway, which I was about to do. The following day, a Toyota dealer indicated that the issue was the brake booster pump/actuator system and that my car returned with error code C1391. The dealer indicated that this is a known problem with Priuses within my year range. I was told that I would have to replace both the pump and actuator. After talking to the dealer, I realized that there had been subtle clues of this problem beforehand. In the few months leading up to this incident, sometimes if I hit a big bump in the road, for a moment the Slip indicator light would flash and I would feel like I had no control of the car i.e. I was ever so briefly slipping. However, because this happened so briefly and when I hit a bump and everything went back to normal, I didn't think this was an actual problem, but now I believe this was an early sign of the brake failure. I contacted Toyota Corporate Office. They confirmed that this was an issue known to them with Priuses and said that they had sent letters to the previous owner of the car in 2019 offering an extended warranty not a recall. However, apparently, the previous owner had not fixed the problem and the extended warranty expired. Toyota refused to pay for the repair for this and refused to forward a copy of the 2019 letter to me,. This brake defect is a serious issue with no major warning signs. As of this writing, the part is available for inspection.

The contact owns a 2014 Toyota Prius V. The contact stated that while driving at an undisclosed speed, the brake pedal was firm which made it hard to stop the vehicle. No warning light was illuminated. The vehicle was diagnosed by a dealer, and it was determined that there was a leak in the brake booster pump assembly. The vehicle had not been repaired. The manufacturer was made aware of the failure and informed the contact that parts to repair the vehicle was not available. The failure mileage was approximately 142,000.

My wife opened the tailgate and the right side lift support exploded. A person standing across the parking lot thought it sounded like a gun shot. Small metal pieces flew about the cargo area in the car. When my wife then tried to close the tailgate the lift support bent. She was then able to disconnect it and close the tailgate. I included a picture of the remaining left side support plus the broken right side and where it was mounted.

The contact owns a 2014 Toyota Prius C. The contact stated while driving at an undisclosed speed, the vehicle lost motive power.

The vehicle was taken to the dealer, but the vehicle was not diagnosed or repaired. The contact stated that the failure had recurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 73,211.

The contact owns a 2014 Toyota Prius. The contact stated was unable to start the vehicle. Additionally, the hybrid system warning light was illuminated. The vehicle was not drivable. The contact towed the vehicle to the local dealer, where it was diagnosed with needing the inverter assembly to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 20V369000 (Hybrid Propulsion System). The manufacturer was informed of the failure and the contact was informed that the recall repair had been performed on August 20, 2020. The failure mileage was approximately 86,500.

At a stop light, when the light turned green, I took my foot off the brake and pressed the gas pedal but the car did not advance forward. Instead it was as though the car was in neutral and it began to roll backwards because I was on a slight slope. I attempted to get the car to move forward by engaging in shifter into Drive, but nothing changed (still as though it was in neutral). I heard a whirring sound but couldn’t tell where it was coming from. The only way I could get it to drive was to turn the car off and restart. This happened twice before I could get where I was going. Fortunately it didn’t result in an accident but I’m afraid to drive the car now.

Good Evening, I'm writing to request a callback in regards to my 2014 Toyota Prius which is subject to a recall. "The involved vehicles were designed to enter a failsafe driving mode in response to certain hybrid system faults. Toyota has found that in rare situations, the vehicle may not enter a failsafe driving mode as intended. If this occurs, the vehicle could lose power and stall. While power steering and braking would remain operational, a vehicle stall while driving at higher speeds could increase the risk of a crash." I recently just moved back to South Florida, I was living in NJ for a few years and had the Inverter malfunction earlier this February, 2023, forcing the car to enter the fail safe mode described giving me the warning to "Check Hybrid System, Stop the Vehicle in a Safe Place". The car was at Toyota Universe, Little Falls, NJ for about 45 days, since this was going to take the complete replacing of the inverter and an update of some sort of software. After receiving the car back around March 17th, I moved back to Florida about 2 weeks later. This evening around 5:30 returning from work, the car stalled again while I was driving surrounded by dense traffic, wouldn't accelerate with all lights flashing. Thankfully I was able to pull over slowly into a parking lot after which my steering wheel locked, and my car was no longer able to be put into Drive or Reverse. Car was only able to shift into Neutral and Park. This was the most terrifying experience of my life had something worse happen in the middle of traffic. I have dropped off my car to the dealership parking lot and will be checking it in first thing in the morning. I'd like to ascertain what I should expect from Toyota Manufacturing should this issue be unfixable? I am more than happy to let them attempt fixing it, but I also need to live a normal life and don't feel the need to be responsible for a manufacturing defect putting my life in jeopardy every time I go drive.

Was at Toyota dealership looking at 2023 Prius and 2023 Corolla Cross for daughter. I decided to leave and when I started backing up, my daughter noticed the Brake, ABS and Anti-Skid lights all came on at once. She asked if that was normal. It was not. A few minutes later, they stated flashing, then went out after I turned the car off. I live over an hour away and decided to drive it to Walmart, which is approximately 2 miles from the dealership and upon getting into the Walmart parking lot the lights started flashing again and upon applying the brakes, we heard a loud grinding sound. We didn’t think we were going to be able to stop! I immediately parked it and called my husband to tell him our horror story and to come pick us up. Our prayers were answered when he came and we were able to drive it slowly to the dealer. It was a cold rainy night to be on the road with braking issues. This is a very dangerous if not deadly situation! Shame on Toyota for not recalling this. How many lives have to be lost before you take ownership of your faulty hybrid braking system. We demand this be fixed for free regardless of mileage and be made a recall…NOT A CUSTOMER SUPPORT PROGRAM. RIDICULOUS!!! I don’t think our daughter wants a Toyota hybrid anymore…
