Summary

ToyotaeBay Motor Engineering & Manufacturing (ToyotaeBay) is recalling certain 2023 Mirai, Lexus LS500, LS500H, 2023-2024 Lexus ES250, ES300H, ES350, 2024 Lexus LC500, and LC500H vehicles equipped with a Panoramic View Monitor (PVM) system. Due to incorrect programming of the parking-assist electronic control unit (ECU) software, the rearview camera image may not immediately display within a couple of seconds after the shifter is placed into reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, “Rear Visibility.”

 

Remedy

Dealers will update the parking assist ECU software, free of charge. Owner notification letters are expected to be mailed April 7, 2024. Owners may contact ToyotaeBay customer service at 1-800-331-4331. ToyotaeBay’s numbers for this recall are 24TA01 and 24LA01.

SAFETY (NONCOMPLIANCE) RECALL 24LA01 (Remedy Notice)
Multiple Models and Model Years
PVM System May Not Display Required Images

On February 21, 2024, Lexus 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 – 2024 Model Year ES250, Certain, 2023 – 2024 Model Year ES300h, Certain 2023 – 2024 Model Year ES350, Certain 2024 Model Year LC500, Certain 2024 Model Year LC Convertible, Certain 2024 Model Year LC500h, Certain 2023 Model Year LS500, and Certain 2023 Model Year LS500h 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 

Lexus dealers will update the software in the Parking Assist ECU FREE OF CHARGE.

 

Covered Vehicles

There are approximately 16,500 vehicles covered by this Safety Recall. Approximately 10 vehicles involved in this Safety Recall were distributed to Puerto Rico.

 

Owner Letter Mailing Date

Lexus will notify owners by late April 2024.

 


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.

 

Test Results and Other Information:

In February 2023, ToyotaeBay 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, ToyotaeBay 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. ToyotaeBay and the supplier began replication testing focusing on the sequence.

In early February 2024, ToyotaeBay was able to replicate the issue. ToyotaeBay’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, ToyotaeBay 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.

 

Description of Corrective Repair Action:

All known owners of the subject vehicles will be notified to return their vehicles to a ToyotaeBay or Lexus dealer. The dealers will update the software of the Parking Assist ECU, free of charge.
