2013 Toyota Prius C

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

The contact owns a 2013 Toyota Prius C. The contact stated that while his wife was attempting to cold-start the vehicle, the vehicle failed to start. The contact stated that on several occasions the vehicle was started; however, the instrument cluster and other electrical devices failed to operate as needed. The contact replaced the auxiliary battery. The vehicle was repaired, but the failure reoccurred, and the vehicle needed to be jump-started. The vehicle was not taken to a local dealer or independent mechanic to be diagnosed or repaired. The contact researched online and related the failure to NHTSA Campaign Number: 20V369000 (Hybrid Propulsion System); however, the VIN was not included in the recall. The manufacturer was not informed of the failure. The failure mileage was approximately 150,000.

Car suddenly needed a jump start and again after a day or two of non-use. On the third day Brakes, ABS and traction control warnings were lighted up and remains. Brakes are mostly ineffective. My own scan returns the code C1252 and C1256 that says brake booster system failing. Took it to the dealer who charged $290 again to scan and came up with failed brake booster and pump assembly. The dealers is quoting total $4000 to fix. Toyota Customer Support Program Bulletin dated 8/2018 and revised on 8/2019 extends the warranty on for this issue (for Toyota Prius C 2013) for 10 years or 150000 miles. I was never informed by Toyota or the seller (Stevens Creek Toyota, San Jose CA) about this defect under warranty that I could have gotten repaired well before the dead line of 10 years. Now Both Toyota or the dealer's service department refuse to bear the repair cost.

Warning lamps for ABS and others and the chiming dings came on while pulling away from the bank drive through and parking for a second. I shut the engine off and turned back on with no success. I was barely able to park in a spot because of difficulties braking. My car had been making an electric noise every 15 seconds or so previously, at different times when parked, but I thought it was the hybrid engine. Now I think it was the brake pump trying to build up pressure due to a faulty, leaking brake actuator.

My 2013 Toyota Prius has a failed inverter/converter assembly, including the Intelligent Power Module (IPM). This component is critical for vehicle operation and designed to last the life of the car. Premature IPM shorting and inverter failure is a known defect acknowledged by Toyota through multiple recalls and service campaigns for other VINs with the same part number. My vehicle is giving codes P0A94 and P0A1A which are also listed in the recalls for other Prius models of similar age. My vehicle experiences the same failure, yet Toyota has denied goodwill coverage, claiming “insufficient service history.” Routine maintenance like oil changes and brake inspections does not affect this component, making the denial unreasonable. There is nothing to service on the inverter. This defect poses a serious safety risk, sudden inverter failure caused total loss of power while driving and loss of power steering, it was difficult to pull my car off the road. This poses a danger to drivers, passengers, and others on the road. Toyota’s exclusion of my VIN from coverage leaves me financially responsible for a known safety defect. I request NHTSA to investigate Toyota’s handling of inverter/IPM failures, the denial of goodwill assistance for affected VINs, and ensure that Toyota addresses this life-threatening defect consistently across all affected vehicles instead of narrowing the scope on who gets coverage when this is a dangerous electrical malfunction.

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.

Recently the dash board lights started intermittently coming on. When they are on, the brakes do not work until pressed all the way to the floor and even then the car takes a long time to stop. The lights will randomly turn off and suddenly the car brakes work normally again. It is happening intermittently with no rhyme or reason as to when it will happen. It's scary to drive because I dont know if the brakes will work or not and I almost ran into another car when trying to stop at a stop light. I took the car to be inspected at the Toyota service center for $190 and after inspection they said the brake booster and master cylinder assembly need to be replaced and it will cost $2300.

OBSOLETE NOTICE February 13, 2026: This bulletin is now obsolete. Please see T-SB-0009-26.

This bulletin includes basic procedures for performing a rescue charge on Ni-MH high voltage (HV) batteries. This bulletin should be used in conjunction with the applicable model and model year Repair Manual while performing a rescue charge. The GRX-5100 should be used wherever the Repair Manual references the Toyota Hybrid System (THS) charger.

Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.

The air conditioning dye injection tool kit has been developed to aid in identifying the location of air conditioning refrigerant leaks. The procedures outlined in this Service Bulletin aid in locating, inspecting, and repairing refrigerant leaks.

Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: •Minor damage: requires only buffing to repair. •Moderate damage: usually requires neutralizing, color sanding, and buffing. •Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
