TOYOTA PRIUS C

HYBRID PROPULSION SYSTEM

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018-2019 Prius C vehicles. The DC-DC converter may fail resulting in the auxiliary battery no longer receiving power from the converter, which may cause a loss of drive.

Risk: A loss of drive increases the risk of crash.

EQUIPMENT:OTHER:LABELS

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018 Toyota Prius C vehicles sold in Puerto Rico. The front passenger air bag and recommended child occupant seating positions label may not have been attached during assembly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Risk: If the label is missing, occupants may not follow the proper restraint usage guidelines, increasing the risk of injury in the event of a crash.

TIRES:TEMPORARY/EMERGENCY SPARE TIRE

Gulf States Toyota, Inc. (Gulf States) is recalling certain 2017 4Runner , 86, Avalon, Camry, Camry Hybrid, Corolla, Corolla iM, Highlander, Highlander Hybrid, Prius, Prius C, RAV4, RAV4 Hybrid, Sienna and Yaris vehicles. The spare tire air pressure was not adjusted to the proper pressure as stated on the Tire Pressure Label.

Risk: A spare tire that is not inflated to the proper value may not perform as intended, increasing the risk of a crash.

HYBRID PROPULSION SYSTEM: INVERTER

The contact owns a 2013 Toyota Prius C. The contact stated that while driving at 25 MPH, the vehicle stalled and failed to restart. The contact stated that he and his wife were in the vehicle during the failure, and the vehicle was almost crashed into. The contact stated that he and his wife were left stranded in oncoming traffic. The vehicle was towed to the dealer, where it was diagnosed that there was a computer failure and that the inverter converter assembly needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 75,421.

AIR BAGS

The contact was driving a company-owned 2017 Toyota Prius C. The contact stated that while driving at 65 MPH, another driver merging onto the highway attempted to cross multiple lanes of traffic, misjudged, and collided with the front passenger-side fender of the contact’s vehicle. As a result, the contact’s vehicle struck the left shoulder barrier, became airborne, and overturned three times before coming to rest in the middle of the roadway. Despite the severity of the crash, the air bags did not deploy. No warning lights were illuminated. The vehicle was towed to a storage facility and deemed a total loss by the employer’s insurance provider. A police report was filed, and injuries were reported. The contact was transported by EMTs to a local hospital and treated for multiple nondescript injuries, including a damaged right rotator cuff and body pain. The contact also underwent chest and torso X-rays due to concerns of possible internal bleeding. The manufacturer was not notified of the failure. The failure mileage was unknown.

SERVICE BRAKES

I own a 2012 Toyota Prius C with approximately 156,578 miles. The vehicle has been diagnosed with C1391 – Abnormal Leak in Accumulator, which causes the brake actuator to lose hydraulic pressure. This results in frequent buzzing from the actuator pump, illuminated warning lights (BRAKE, ABS, Traction Control), and loss of ABS and stability control. The condition increases stopping distance and creates a serious safety hazard. Toyota previously acknowledged this exact defect under Customer Support Program CSP 21TE01, which covered brake booster and pump assemblies for certain Prius and Prius C models when codes such as C1391 were present. However, the program expired on November 30, 2022, and my vehicle is just over the 150,000-mile coverage limit. Despite this, my Prius exhibits the same defect that Toyota has already recognized as a safety-related issue. Toyota Carlsbad confirmed the diagnosis and quoted $3,399.55 plus tax for repair, with a reduced courtesy estimate of $2,817.86 plus tax, but declined goodwill assistance since CSP 21TE01 expired. Given the widespread reports of brake actuator failures in Prius models, I believe this represents a systemic safety issue that warrants NHTSA investigation and potential recall/extended coverage.

TIRES

P 175/65r15 I was driving on a slight curve on the I-10 in El Paso, TX when the rear bumper exploded. The car started swaying and swerving then I pulled over. I then realized that the tread on the tire was gone floating across the highway. The trie was bare with no tread with the bumper around the tire was gone. The explosion also caused the tail light to break.

SERVICE BRAKES

I was told that my Brake Booster and Brake Booster Pump Assembly needed replaced. I had specifically asked my dealership in the past if there were any issues with my car and was told that there was nothing, which was untrue. I called Toyota and was told that I was mailed something back in 2018, but I do not remember receiving it. Now I am told that this has expired. I wanted to know if I had any recourse or extension time on this program 21 TE01. I am afraid that my brakes will not work, as the lights go off and on.

SERVICE BRAKES

Brake Actuator and ABS Accumalator failed. It is a common failure reported by multiple owners on these cars. I was on the high way going 70 when it failed and lost any brake boost I had putting me in a very dangerous situation where I narrowly avoided an accident. Upon scanning the car's codes I got code C1391 which I looked up and saw a bunch of other people who were also struggling with this issue.

VEHICLE SPEED CONTROL

Cruise Control Not Working. Traction Control Light Active, Brake Light Active, And Light Active The cause was diagnosed by Toyota of Paris. TSB for C1391 Code abnormal leak in accumulator. The corrective action is to replace brake booster assembly with Master cylinder and Brake Booster pump Assembly.
