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 listed above which are equipped with the Parking Assist ECU containing the specific software logic from the specific supplier.
3. Total Number of Vehicles Potentially Involved:
Toyota Mirai : 2,088
Lexus ES250 : 100
Lexus ES300h : 6,378
Lexus ES350 : 7,559
Lexus LC500 : 1,016
Lexus LC500h : 23
Lexus LS500 : 1,451
Lexus LS500h : 1
Total : 18,616
4. Percentage of Vehicles Estimated to Actually Contain the Noncompliance:
100% of the involved vehicles contain a Parking Assist ECU with the improper software programming described in Section 5 below. Whether this issue, in each case, will cause the rearview image not to be displayed within two seconds of the start of the backing event depends on whether the camera initialization process fails, as described in Section 6 below.
5. Description of Noncompliance:
The subject vehicles are equipped with a Panoramic View Monitor (PVM) system, which consists of multiple individual cameras located around the vehicle, including a rearview camera, and a Parking Assist ECU. The PVM system uses the Parking Assist ECU to activate the signal for each of these cameras, as needed, in order to display the corresponding image. Due to improper programming of the Parking Assist ECU software, if a camera initialization process failure occurs, the PVM system may not display a rearview image within two seconds of the start of the backing event if the driver shifts into reverse within approximately four seconds after ignition is switched on. As a result, the subject vehicles fail to comply with the requirements of FMVSS No. 111, paragraph S5.5.3, which may increase the risk of a crash during a backing event.
6. Test Results and Other Information:
In February 2023, Toyota and the Parking Assist ECU supplier began a design review of all PVM systems in parallel with an investigation of an issue involving the rearview monitor on a certain vehicle model sold in Japan. Based on the review, it appeared that if there is a large amount of data being processed at vehicle startup, the camera initialization process could fail at vehicle startup on certain PVM systems. Beginning in September 2023, Toyota and the supplier
specifically investigated the initialization sequence of the Parking Assist ECU and identified that when large amounts of data are processed at vehicle startup, the camera initialization process may conflict with the image drawing process, and the image drawing process would be prioritized, causing the camera initialization process to fail. Toyota and the supplier began replication testing focusing on the sequence.
In early February 2024, Toyota was able to replicate the issue. Toyota’s analysis also found that if the initialization process failure occurred and the driver shifts into reverse within four seconds after the ignition is switched on, it would take more than two seconds after the start of the backing event to display the rearview image.
On February 15, 2024, Toyota determined that it is possible that the involved vehicles could experience a condition in which a rearview image does not display to the driver within two seconds of the start of a backing event and as such, does not meet the requirements of FMVSS No. 111 S5.5.3 and decided to conduct a recall.
7. Description of Corrective Repair Action:
All known owners of the subject vehicles will be notified to return their vehicles to a Toyota or Lexus dealer. The dealers will update the software of the Parking Assist ECU, free of charge.
Reimbursement Plan for pre-notification remedies
As the owner notification letters will be mailed out within the active period of the Toyota or Lexus New Vehicle Limited Warranty (“Warranty”) and all involved vehicle owners for this recall would have been provided a repair at no cost under Toyota’s Warranty.
8. Recall Schedule:
Notifications to owners of the affected vehicles will occur by April 21, 2024. A copy of the draft owner notification will be submitted as soon as it is available.
9. Distributor/Dealer Notification Schedule:
Notifications to distributors/dealers will be sent on February 21, 2024. Copies of dealer communications will be submitted as they are issued.

On February 21, 2024, Toyota will file 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 Certain 2023 Mirai vehicles.
Condition
Due to a software programming issue, the rearview image may not display within the period of time required
by certain U.S. safety regulations after the driver shifts the vehicle into reverse, increasing the risk of a crash
while backing the vehicle.
Remedy
Toyota dealers will update the software in the Parking Assist ECU FREE OF CHARGE.
Covered Vehicles
There are approximately 2,100 vehicles covered by this Safety Recall.
Owner Letter Mailing Date
Toyota will notify owners by late April 2024.
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.

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.
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 40 vehicles in new dealer inventory as of February 19, 2024.
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.

The PVM system uses the Parking Assist ECU to activate the signal for each of these cameras, as needed, in order to display the corresponding image. Due to improper programming of the Parking Assist ECU software, if a camera initialization process failure occurs, the PVM system may not display a rearview image within two seconds of the start of the backing event if the driver shifts into reverse within approximately four seconds after ignition is switched on. As a result, the subject vehicles fail to comply with the requirements of FMVSS No. 111, paragraph S5.5.3, which may increase the risk of a crash during a backing event. FMVSS 1 : 111 – Rear visibility FMVSS 2 : NR
Description of the Safety Risk : Due to improper programming of the Parking Assist ECU software, if a camera initialization process failure occurs, the PVM system may not display a rearview image within two seconds of the start of the backing event if the driver shifts into reverse within approximately four seconds after ignition is switched on. As a result, the subject vehicles fail to comply with the requirements of FMVSS No. 111, paragraph S5.5.3, which may increase the risk of a crash during a backing event.

In February 2023, Toyota and the Parking Assist ECU supplier began a design review of all PVM systems in parallel with an investigation of an issue involving the rearview monitor on a certain vehicle model sold in Japan. Based on the review, it appeared that if there is a large amount of data being processed at vehicle startup, the camera initialization process could fail at vehicle startup on certain PVM systems. Beginning in September 2023, Toyota and the supplier specifically investigated the initialization sequence of the Parking Assist ECU and identified that when large amounts of data are processed at vehicle startup, the camera initialization process may conflict with the image drawing process, and the image drawing process would be prioritized, causing the camera initialization process to fail. Toyota and the supplier began replication testing focusing on the sequence. In early February 2024, Toyota was able to replicate the issue. Toyota’s analysis also found that if the initialization process failure occurred and the driver shifts into reverse within four seconds after the ignition is switched on, it would take more than two seconds after the start of the backing event to display the rearview image. On February 15, 2024, Toyota determined that it is possible that the involved vehicles could experience a condition in which a rearview image does not display to the driver within two seconds of the start of a backing event and as such, does not meet the requirements of FMVSS No. 111 S5.5.3 and decided to conduct a recall.
