If service parts are found to be affected, this filing will be amended. (3) Only vehicles in the above production range may have been equipped with the spiral cable assembly that includes a Flexible Flat Cable (FFC) that may not have been welded sufficiently due to a specific production issue and are involved in this recall. Other Toyota and Lexus vehicles are not equipped with the spiral cable assemblies that include the affected FFC produced at a specific supplier during a specific production period. 3. Total Number of Vehicles Involved: Toyota Corolla : 26,675 Toyota Corolla Cross : 14,203 Toyota Corolla Cross Hybrid : 138 Toyota Highlander : 21,597 Toyota Highlander Hybrid : 4,554 Toyota Tacoma : 38,561 Lexus RX350 : 1,135 Lexus RX350 Hybrid : 13 Lexus RX500 Hybrid : 33 Lexus NX250 : 2,335 Lexus NX350 : 791 Lexus NX350 Hybrid : 12 Total : 110,047 4. Percentage of Vehicles Estimated to Actually Experience Noncompliance: 11.3 % of the involved vehicles contain the part that could be affected by the condition described in Section 5 below. Whether the issue, in each case, will cause the FFC to separate on the driver’s airbag module circuits rather than other circuits cannot be determined. 5. Description of Noncompliance: The steering column assembly in the subject vehicles contains electrical connections to the driver’s airbag module housed in a spiral cable assembly, which includes a Flexible Flat Cable (FFC). Due to an insufficient weld condition of the FFC to the spiral cable’s bus bar, there is a possibility that the FFC can separate, resulting in one or more open circuits connected through the FFC. This separation could occur on the circuit that provides connectivity to the driver’s airbag module. If connectivity is lost, the SRS warning light will illuminate and the driver’s airbag could become deactivated, causing it to not deploy in the event of a crash of the type that would cause deployment. As a result, the vehicles may not comply with some requirements of FMVSS No. 208 where driver’s airbag deployment is needed. This could result in an increased risk of injury to the driver in a crash. 6. Test Results and Other Information: In Mid-May, 2023, the spiral cable assembly supplier notified Toyota of a manufacturing process investigation which found contamination in a washing station for certain spiral cable components that caused a poor welding condition between the FFC and the bus bar. The FFC provides connectivity to various controls on the steering wheel. From late-May to late-June, the supplier conducted testing to determine the effects of contamination, which indicated that the FFC could separate from the bus bar at the poor weld connection area. As a result of the investigation, Toyota determined on July 6, 2023, that the involved vehicles may have a condition present at the time of manufacturing and point of first sale in which the FFC weld separation can deactivate the driver’s airbag, which would cause the vehicle not to meet certain requirements of FMVSS No. 208 where driver’s airbag deployment is needed. 7. Description of Corrective Repair Action: All known owners of the involved vehicles will be notified to return their vehicles to a Toyota or Lexus dealer. For all involved vehicles, dealers will inspect the Spiral Cable Assembly production date and replace the Spiral Cable Assembly, if necessary, at no cost to owners. Reimbursement Plan for pre-notification remedies As the owner notification letters will be mailed out well within the active period of the Toyota or Lexus New Vehicle Limited Warranty (“Warranty”), all involved vehicle owners for this recall would have been provided a repair at no cost under theWarranty. 8. Recall Schedule: Notifications to owners of the affected vehicles will occur by September 10, 2023. A copy of the draft owner notification letter(s) will be submitted as soon as available. 9. Distributor/Dealer Notification Schedule: Notifications to distributors/dealers will be sent by July 12, 2023. Copies of dealer communications will be submitted as they are issued. 10.

DO NOT SELL NEW VEHICLES IN DEALER INVENTORY. Refer to Dealer Inventory Procedures section for more details. On July 12, 2023, Toyota filed a Noncompliance Information Report (NCIR) with the National Highway Traffic Safety Administration (NHTSA) informing the agency of our intent to conduct a voluntary Safety (Noncompliance) Recall on 2023 model year Corolla, Corolla Cross, Corolla Cross HV, Highlander, Highlander HV and Tacoma vehicles. Condition In the affected vehicles, the spiral cable assembly in the steering column may lose its electrical connection on the circuit controlling the driver’s airbag. If this occurs, the airbag warning light will illuminate, and the driver’s airbag may not deploy in a crash. As a result, the vehicle will not comply with certain federal motor vehicle safety requirements and may increase the risk of injury to the driver in the event of a crash. Remedy Toyota is currently preparing the remedy for this issue. When the remedy is available, Toyota dealers will inspect the serial number of the spiral cable and, if necessary, replace it with a new cable FREE OF CHARGE. At this time, Toyota estimates the remedy can be made available in the next couple months. However, this is subject to change. Covered Vehicles There are approximately 105,850 vehicles covered by this Safety (Noncompliance) Recall. Approximately 1,800 vehicles involved in this Safety (Noncompliance) Recall were distributed to Puerto Rico. Owner Letter Mailing Date Toyota will notify owners by early September 2023. Toyota makes significant effort to obtain current customer name and address information from each state through industry resources when mailing owner letters. In the event your dealership receives a notice for a vehicle that was sold prior to the Safety (Noncompliance) Recall announcement, it is the dealership’s responsibility to forward the owner letter to the customer who purchased the vehicle.

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. Dealers should perform the repair as outlined in the Technical Instructions found on TIS. Dealer Inventory Procedures New Vehicles in Dealership Inventory There are approximately 1,510 vehicles in new dealer inventory as of July 10, 2023. Under Title 49, Section 30112 of the United States Code, a dealer cannot sell, offer for sale, or introduce or deliver for introduction in interstate commerce a new motor vehicle when it is aware that the vehicle does not comply with an applicable Federal Motor Vehicle Safety Standard or contains a defect related to motor vehicle safety. Further, 49 Code of Federal Regulations §577.13 requires us to provide the following advisory: It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied. Toyota reimburses dealers for flooring costs associated with new vehicles held in dealership inventory until the recall remedy becomes available. Toyota provides these flooring reimbursements at 60-day intervals. Toyota reserves the right to withhold or charge-back any flooring reimbursement funds that may have been paid to the dealer if it determines that a new vehicle subject to a safety recall was sold without first being remedied. Vehicle Safety Recall completion should always be verified through TIS. We request your assistance to ensure involved vehicles are identified and not delivered prior to performing the remedy. NOTE: • New vehicles in dealer inventory subject to a Safety Recall must be remedied before delivery into commerce under a sale or lease. Dealer-to-dealer trades as well as vehicle sales between dealers should not be made until a vehicle is remedied. • Dealers can identify if any of their new and used inventory has any open campaigns in the Vehicle Inventory Summary available in Dealer Daily (Non SET and GST dealers: https://dealerdaily.toyota.com/). The Vehicle Inventory Summary may take up to 4 hours to populate information for newly launched campaigns. Inspection Reminder Mirror Hang Tags for Covered Vehicles in New Dealer Stock To easily recognize vehicles involved in this Safety (Noncompliance) Recall, each dealership should utilize Inspection Reminder Hang Tags. Inside the vehicle’s glove box are stickers containing the VIN. Apply one of these stickers to the hang tag and install the hang tag in the vehicle. A sample copy of the Inspection Reminder Hang Tag has been included for your reference. Pre-Owned Vehicles in Dealer Inventory Toyota typically requests that dealers NOT deliver any pre-owned vehicles in dealer inventory that are covered by a Safety (Noncompliance) Recall unless the defect has been remedied. In this case, until remedy parts are available, delivery of a pre-owned vehicle is acceptable if disclosed to the customer that the vehicle is involved in this Safety (Noncompliance) Recall and that the remedy is currently being prepared by Toyota. NOTE: Dealerships can order hang tags from the Material Distribution Center (MDC).

Production Dates : MAR 06, 2023 – MAY 30, 2023 VIN Range 1 : Begin : NR End : NR Not sequential Description of Noncompliance : Description of the Noncompliance : The steering column assembly in the subject vehicles contains electrical connections to the driver’s airbag module housed in a spiral cable assembly, which includes a Flexible Flat Cable (FFC). Due to an insufficient weld condition of the FFC to the spiral cable’s bus bar, there is a possibility that the FFC can separate, resulting in one or more open circuits connected through the FFC. This separation could occur on the circuit that provides connectivity to the driver’s airbag module. If connectivity is lost, the SRS warning light will illuminate and the driver’s airbag could become deactivated, causing it to not deploy in the event of a crash of the type that would cause deployment. As a result, the vehicles may not comply with some requirements of FMVSS No. 208 where driver’s airbag deployment is needed. This could result in an increased risk of injury to the driver in a crash. FMVSS 1 : 208 – Occupant crash protection FMVSS 2 : NR Description of the Safety Risk : As a result, the vehicles may not comply with some requirements of FMVSS No. 208 where driver’s airbag deployment is needed. This could result in an increased risk of injury to the driver in a crash. Description of the Cause : NR Identification of Any Warning that can Occur : NR Part 573 Safety Recall Report 23V-480 Page 8 The information contained in this report was submitted pursuant to 49 CFR §573 Involved Components : Component Name 1 : Cable Sub-Assy, Spiral Component Description : Spiral Cable Assembly Component Part Number : 84306-0A010 Component Name 2 : Cable Sub-Assy, Spiral Component Description : Spiral Cable Assembly Component Part Number : 84306-0E180 Component Name 3 : Cable Sub-Assy, Spiral Component Description : Spiral Cable Assembly Component Part Number : 84306-0E090 Component Name 4 : Cable Sub-Assy, Spiral Component Description : Spiral Cable Assembly Component Part Number : 84306-F6020 Supplier Identification : Component Manufacturer Name : American Furukawa, Inc. Address : 47677 Galleon Dr. Plymouth Michigan 48170 Country : United States Chronology : In Mid-May, 2023, the spiral cable assembly supplier notified Toyota of a manufacturing process investigation which found contamination in a washing station for certain spiral cable components that caused a poor welding condition between the FFC and the bus bar. The FFC provides connectivity to various controls on the steering wheel. From late-May to late-June, the supplier conducted testing to determine the effects of contamination, which indicated that the FFC could separate from the bus bar at the poor weld connection area. Part 573 Safety Recall Report 23V-480 Page 9 The information contained in this report was submitted pursuant to 49 CFR §573 As a result of the investigation, Toyota determined on July 6, 2023, that the involved vehicles may have a condition present at the time of manufacturing and point of first sale in which the FFC weld separation can deactivate the driver’s airbag, which would cause the vehicle not to meet certain requirements of FMVSS No. 208 where driver’s airbag deployment is needed. Description of Remedy : Description of Remedy Program : All known owners of the involved vehicles will be notified to return their vehicles to a Toyota or Lexus dealer. For all involved vehicles, dealers will inspect the Spiral Cable Assembly production date and replace the Spiral Cable Assembly, if necessary, at no cost to owners. As the owner notification letters will be mailed out well within the active period of the Toyota or Lexus New Vehicle Limited Warranty (“Warranty”), all involved vehicle owners for this recall would have been provided a repair at no cost under the Warranty. How Remedy Component Differs from Recalled Component : NR Identify How/When Recall Condition was Corrected in Production : NR Recall Schedule : Description of Recall Schedule : Notifications to owners of the affected vehicles will occur by September 10, 2023.
