There are three parts subject to this recall. They are listed below.

Steering device (control computer for lane tracing assist)

Due to an inappropriate control program in the LTA of the driving support device, there are cases where the steering wheel correction in the LTA is insufficient due to the deviation of the neutral position of the steering wheel steering angle. Therefore, depending on the curve and vehicle speed conditions, an early warning may be activated and the driver may be required to steer the vehicle.

Others (Display Audio)

In display audio, when the vehicle is restarted during navigation route guidance due to an inappropriate control program, and the image of the panoramic view monitor is immediately displayed, or when the navigation guide map is displayed over the image on the left side of the vehicle. It is said that there is As a result, the image on the left side of the vehicle cannot be confirmed, and there is a risk that it will not comply with Article 44 of the safety standards (standards for rearview mirrors, etc.).

Braking device (control computer for brake actuator)

In the electric parking brake, the abnormality detection program of the control computer power supply circuit is inappropriate, so the temporary response delay that occurs in the circuit may be erroneously determined as an abnormality. Therefore, it seems that the warning light will turn on and the electric parking brake may not operate.
