Mitsubishi Fuso Truck & Bus Corp. on Wednesday said it is recalling a total of about 42,000 trucks and buses in five separate defect cases, of which two were found previously, Kyodo News reported.

In one of the five cases, Mitsubishi Fuso, which has been involved in a series of defect cover-ups, will recall some 37,000 vehicles manufactured from 1998 to 2004 due to a defect in the clutch system. Its attachment device lacks strength and may crack, making gear changes impossible.

This is among 15 defect cases the company reported to the Ministry of Land, Infrastructure and Transport on Tuesday, although they were found more than a year ago.

Another recall is intended to repair more than 1,000 large buses because of a defect in the air compressor for the braking system. The defect surfaced as a result of the company's investigation into its past repair documents.

Mitsubishi Fuso tried to secretly fix the defect in 1997, according to the investigation, Kyodo News noted.
