Affected vehicles
日車 12.3ton LNG Tank Semi-trailer 2003–2007
Hazard
The pressurized evaporator on the LNG tank semi-trailer has an improper mounting structure to the vehicle body, which can cause cracks to develop in the frame surrounding the pressurized evaporator due to vibration during operation. If use continues in this condition, the pressurized evaporator may detach, potentially obstructing other traffic in the worst case.

Remedy
For all vehicles, change the pressurized evaporator mounting brackets from suspended fixed type to lower support type. Additionally, inspect the frame surrounding the pressurized evaporator and perform welding repairs on any units with cracks.
