Defect	Due to improper assembly during manufacturing, some nuts at the body ground terminal points for the 12V and 48V ground wiring under the floor are not tightened to the specified torque. As a result, vibrations during driving may cause these nuts to loosen, increasing electrical resistance, which can lead to heat generation that melts surrounding components, and in the worst case, potentially cause a fire.
