 | STOP! DO NOT SELL NEW VEHICLES IN DEALER INVENTORY.
Refer to Dealer Inventory Procedures section for more details. | |
On June 26, 2019, Toyota filed a Defect Information Report (DIR) with the National Highway Traffic Safety Administration (NHTSA) informing the agency of our intent to conduct a voluntary Safety Recall on 2018 โ 2019 model year Prius C vehicles.
Condition
Due to a manufacturing issue, a component may stop performing its function of converting power from the hybrid vehicle battery for use by certain vehicle systems. If this occurs, warning lights will illuminate, audible chimes will sound, and messages will be displayed on the instrument panel. If the vehicle continues to be operated, it could lose motive power. Loss of motive power while driving at higher speeds could increase the risk of a crash.
Remedy
Based on the vehicle identification number (VIN) or an inspection, any authorized Toyota dealer will replace the affected DC-DC converter with a new one, if necessary, FREE OF CHARGE.
Check Each VIN in TIS
Some involved vehicles have been identified as requiring a replacement of the DC-DC converter based on its VIN. Other involved vehicles will require an inspection first to determine replacement of the DC-DC converter is necessary. To determine if the vehicle requires inspection, please search each VIN using TIS and be sure to check the TIS Memo field (see below images for more detail). Only perform the repair that is required for the specific VIN. If replacement of the DC-DC Converter is performed on a vehicle that doesnโt require the repair, the claim will be subject to debit.
| Phase 1 – No Inspection is Required for DC-DC Converter Replacement |
| This vehicle requires the DC-DC Converter to be replaced based on VIN. No inspection should be performed. |
| Phase 2 – Inspection is Required for DC-DC Converter Replacement |
| This vehicle requires inspection first to determine if DC-DC Converter Replacement is necessary. |
Note: For more details and information regarding the inspection and repair procedure, please refer to the technical instructions.
Covered Vehicles
There are approximately 500 vehicles covered by this Safety Recall. Approximately 10 vehicles involved in this Safety Recall were distributed to Puerto Rico.
Owner Letter Mailing Date

In the event your dealership receives a notice for a vehicle that was sold prior to the Safety Recall announcement, it is the dealershipโs responsibility to forward the owner letter to the customer who purchased the vehicle.
Please note that only owners of the covered vehicles will be notified. If you are contacted by an owner who has not yet received a notification, please verify eligibility by confirming through TIS prior to performing repairs.

State of California Regulations require Toyota to provide the Department of Motor Vehicles with a record of all vehicles that have not had the Safety Recall Campaign completed.
Your Toyota dealer will provide you with a Vehicle Emissions Recall Proof of Correction Form after the campaign has been completed.

VI. SAFETY PRECAUTIONS
CAUTION:
This vehicle has a hybrid control system that operates at voltages of up to 650 V. An organic electrolyte containing carbonic acid esters as its main component is used as the electrolyte for the HV battery. Be sure to follow the instructions in this manual to handle the system correctly. Failure to do so may result in serious injury or electrocution.
(a) Technicians must undergo special training to be able to service and inspect the high-voltage system.
(b) All high-voltage wire harnesses and connectors are colored orange. Do not carelessly touch these wires or components.
(c) When there is a problem with the wire harness or connector of a high-voltage circuit, repairs to the harness or connector should not be attempted. Replace damaged or malfunctioning high voltage cables or connectors.
(d) Before inspecting or servicing the high-voltage system, be sure to follow all safety measures, such as wearing insulated gloves and removing the service plug to prevent electrocution. Carry the removed service plug in your pocket to prevent other technicians from accidentally reconnecting it while you are servicing the vehicle.
NOTICE:
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.
(e) After removing the service plug grip, wait 10 minutes before touching any of the high-voltage connectors and terminals.
HINT:
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
(f) Before using insulated gloves, be sure to check them for cracks, tears and other types of damage by following the manufactures recommendations.
(g) When servicing the vehicle, do not carry metal objects like mechanical pencils or rulers that can be dropped accidentally and cause a short circuit.
(h) Before touching a bare high-voltage terminal, wear insulated gloves and use a tester to make sure that the terminal voltage is 0 V. (i) After disconnecting or exposing a high-voltage connector or terminal, insulate it immediately using insulating tape.
(j) Bolts and nuts for high-voltage terminals should be tightened firmly to the specified torque. Both insufficient and excessive torque can cause failure.
(k) Use the “CAUTION: HIGH VOLTAGE DO NOT TOUCH” sign to notify other technicians that the high-voltage system is being inspected and/or repaired.
(l)After servicing the high-voltage system and before reinstalling the service plug, check again that you have not left a part or tool inside, that the high-voltage terminals are firmly tightened, and that the connectors are correctly connected.
9
(m) When performing work involving high-voltage wires, use either a tool wrapped with vinyl insulation tape or an insulated tool.
(n) When installing hybrid control system components such as the HV battery, make sure that the polarity of all connections is correct.
CAUTION:
โข Do not touch any bare cables that may have high-voltage. If a cable must be touched or if accidental contact is possible, wear insulated gloves and insulate the cable using insulating tape.
โข Visually check the HV battery and the immediate area for any electrolyte leakage. Do not touch any leaked liquid because it could be organic electrolyte that contains carbonic acid esters.
โข The electrolyte is flammable. Keep all ignition sources such as open flame and hot objects away from the electrolyte.
โข Electrolyte leaks may cause acute poisoning if a high concentration of the vapor from the organic solvent is inhaled. In case of inhalation, move the affected person to a place with ample fresh air and let them lie quietly. Seek medical care.
โข In case of skin contact with the electrolyte, wash the area thoroughly with soap and plenty of water, and seek medical care. Immediately remove any contaminated clothing. Prolonged contact with the electrolyte may cause skin irritation.
โข If the electrolyte comes in contact with your eyes, call out loudly for help. Do not rub your eyes. Immediately flush them with a large amount of water for at least 15 minutes and seek medical care.
โข If electrolyte is swallowed, seek medical care immediately. Do not induce vomiting, unless instructed by the doctor.
(1) Wear insulated or rubber gloves, goggles, and safety shoes.
(2) Check the HV battery and immediate area for any electrolyte leakage.
CAUTION:
Do not touch any leaked liquid because it could be the organic electrolyte that contains carbonic acid esters. If contact is unavoidable, wipe the fluid off using a cloth while wearing rubber gloves, goggles and an organic solvent mask. Do not leave electrolyte-contaminated cloths unattended. Place contaminated cloths in an appropriate airtight container and dispose of them according to local regulations.
(3) Do not touch any bare cables that could be high voltage cables. If a cable must be touched or if accidental contact is possible, follow the following instructions: 1) wear insulated gloves and goggles, 2) measure the voltage between the cable and body ground using an electrical tester, and 3) insulate the cable using insulating tape.
(4) If damage to any of the high-voltage components and cables is suspected, cut the high-voltage circuit using the procedure below.
CAUTION:
Do not touch any bare cables that may have high-voltage. If a cable must be touched or if accidental contact is possible, wear insulated gloves and insulate the cable using insulating tape.
CAUTION: โข Before returning the HV battery, make sure to perform recovery inspection. โข Before returning the hybrid vehicle supply stack sub-assembly, make sure to perform recovery inspection. โข Accidents such as electric shock may result if the HV battery or a hybrid vehicle supply stack sub-assembly is disposed of improperly or abandoned. Therefore, make sure to return all HV batteries or hybrid vehicle supply stack assemblies through an authorized collection agent. โข To reduce the risk of fire, the HV battery or hybrid vehicle supply stack assembly must not be stored in an area where it will be exposed to fire or high temperatures.

VI. SAFETY PRECAUTIONS
CAUTION:
This vehicle has a hybrid control system that operates at voltages of up to 650 V. An organic electrolyte containing carbonic acid esters as its main component is used as the electrolyte for the HV battery. Be sure to follow the instructions in this manual to handle the system correctly. Failure to do so may result in serious injury or electrocution.
(a) Technicians must undergo special training to be able to service and inspect the high-voltage system.
(b) All high-voltage wire harnesses and connectors are colored orange. Do not carelessly touch these wires or components.
(c) When there is a problem with the wire harness or connector of a high-voltage circuit, repairs to the harness or connector should not be attempted. Replace damaged or malfunctioning high voltage cables or connectors.
(d) Before inspecting or servicing the high-voltage system, be sure to follow all safety measures, such as wearing insulated gloves and removing the service plug to prevent electrocution. Carry the removed service plug in your pocket to prevent other technicians from accidentally reconnecting it while you are servicing the vehicle.
NOTICE:
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.
(e) After removing the service plug grip, wait 10 minutes before touching any of the high-voltage connectors and terminals.
HINT:
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
(f) Before using insulated gloves, be sure to check them for cracks, tears and other types of damage by following the manufactures recommendations.
(g) When servicing the vehicle, do not carry metal objects like mechanical pencils or rulers that can be dropped accidentally and cause a short circuit.
(h) Before touching a bare high-voltage terminal, wear insulated gloves and use a tester to make sure that the terminal voltage is 0 V. (i) After disconnecting or exposing a high-voltage connector or terminal, insulate it immediately using insulating tape.
(j) Bolts and nuts for high-voltage terminals should be tightened firmly to the specified torque. Both insufficient and excessive torque can cause failure.
(k) Use the “CAUTION: HIGH VOLTAGE DO NOT TOUCH” sign to notify other technicians that the high-voltage system is being inspected and/or repaired.
(l)After servicing the high-voltage system and before reinstalling the service plug, check again that you have not left a part or tool inside, that the high-voltage terminals are firmly tightened, and that the connectors are correctly connected.

Note: (1) Although the involved vehicles are within the above production period range, not all vehicles in this range were sold in the U.S.
(2) This issue only affects the vehicles equipped with a DC-DC converter that uses a circuit board which may have been manufactured under the specific conditions described in this report. Other Toyota or Lexus vehicles sold in the U.S. are not equipped with those DC-DC converters.
3. Total Number of Vehicles Potentially Involved:
464
4. Percentage of Vehicles Estimated to Actually Contain the Defect:
Approximately 10%
Toyota estimates that approximately 10% of the vehicles have the potential to develop the solder separation condition over the lifetime of the vehicle, which could lead to the unreasonable risk to safety described below.
5. Description of Problem:
The hybrid system of the subject vehicles includes a DC-DC converter that reduces the voltage of the electricity from the HV battery in order to charge the auxiliary battery. Due to improper maintenance of specific pallets and pins used for the circuit board soldering process at a supplier, there is a possibility that, when combined with a certain production variation, the soldering of a specific transistor to the circuit board in the DC-DC converter could be inadequate and separate after temperature cycling of solder under normal vehicle operation. As a result, the auxiliary battery may no longer receive power from the DC-DC converter, causing warning lights to illuminate, audible chimes to sound, and messages to display on the instrument panel. If the vehicle is continuously operated in this condition and the auxiliary battery is discharged to a certain level, the hybrid system could shut down, resulting in loss of motive power. Loss of motive power while driving at higher speeds could increase the risk of a crash.
6. Chronology of Principal Events:
July, 2018 โ January, 2019
In July 2018, Toyota received a field technical report from the Japan market indicating that
warning lights illuminated on a Toyota Aqua vehicle and the vehicle would not accelerate when moving out of a parking space. The dealer inspected the vehicle and found illumination of warning lights and a DTC indicating failure of the DC-DC converter, which is a component inside the inverter. The inverter from this vehicle was recovered and investigated. It was found that solder applied to a terminal of a transistor on the circuit board in the DC-DC converter had separated.
Due to the low mileage of the reported vehicle, Toyota hypothesized that a manufacturing error could have caused the solder separation, and the supplier began an investigation of the soldering process for the circuit board during manufacture. Investigation results revealed that the pallet which holds the circuit board during soldering had significant deformation (outside of the specification for the acceptable range of deformation to a pallet). At this point, the supplier inspected their pallets that were being used for this process and identified that two additional pallets used in the same process had a similar out-of-specification condition. These three pallets were eliminated from the soldering process.
Because the supplier process includes checking for deformation of the pallets periodically, the supplier began investigating the cause of the observed pallet deformation by interviewing the operators who were responsible for pallet maintenance and inspection of the pallets. It was determined that the operator performing this function at this time was improperly checking for pallet deformation.
Based on this information, duplication testing was conducted to identify whether the solder separation at the terminal of the transistor on the circuit board observed in the field case could be created by the pallet deformation that existed in the three pallets mentioned above. The testing showed that this pallet deformation could not create the observed solder separation.
The supplier continued its investigation, reviewing the production history and conducting additional interviews with the operator. It was found that the operator responsible for maintaining the soldering equipment and checking for pallet deformation had changed in February 2018. Further, the investigation identified that, during maintenance, this operator is also responsible for making adjustments to the position of the pins in the pallets, which must be adjusted periodically to ensure its correct position is maintained. The further investigation found that these pins had also been improperly adjusted.
Duplication testing was again conducted to identify if there is a possibility that the solder separation at the terminal of the transistor on the circuit board observed in the field case could be created by the aforementioned pallet deformation in combination with the incorrect pin position. In this testing, it was observed that the solder at the terminal of the transistor had partially peeled. To identify if the same solder separation observed in the field case could occur on parts which have partially peeled solder, a heat cycling durability testing was conducted, but no expansion of the peeling which could lead to the solder separation was observed.
February, 2019 โ June, 2019
The investigation was continued to identify any other factors which could lead to the solder separation. It was found that stress on the circuit board at the terminal of the transistor becomes larger if the circuit board is placed in a specific position in one of the three deformed pallets. Duplication testing was conducted, and it was identified that the solder at the terminal of the transistor could peel substantially if the circuit board was soldered by using one of the aforementioned pallets with the incorrectly positioned pins and the circuit board is placed in a specific position in the pallet. Based on the above findings, heat cycling durability testing was conducted, using circuit boards produced under these conditions, to observe if the same solder separation as the failed part could occur. Under these conditions, the solder separation could be duplicated. In addition, Toyota had recovered inverters to determine if there was a possibility that circuit boards soldered using pallets other than the three identified with significant deformation can experience the separation of solder of the terminal of the transistor. Through this activity Toyota observed that circuit boards which were soldered from one of the three deformed pallets exhibited peeling, whereas circuit boards which were soldered using other pallets exhibited no peeling.
As a result of the aforementioned investigations, Toyota concluded that, if a circuit board was soldered by using one of the three aforementioned deformed pallets with the incorrectly positioned pins and the circuit board is placed in a specific position in the pallet, the solder could separate after temperature cycling of solder under normal vehicle operation. In this condition, the auxiliary battery may no longer receive power from the DC-DC converter, causing warning lights to illuminate, audible chimes to sound, and messages to display on the instrument panel. If the vehicle is continuously operated in this condition and the auxiliary battery is discharged to a certain level, the hybrid system could shut down, resulting in loss of motive power.
