Hazard

In the power transmission device, the power supply coil mounting terminal (lead) attached to the control board within the multi-transmission power unit that controls the power system of the chassis has insufficient strength. The lead may fracture due to vibration during operation. As a result, the transmission position may become fixed in neutral during driving, causing the vehicle to become immobilized.

Remedy

All vehicles: replace the multi-transmission power unit with one equipped with the control board replaced with a corrected version.
