Struggling Nissan Motor wants to sell its vehicle parts and materials distribution business in a deal that may be valued at about US$1bn, Bloomberg and other media reported.

The automaker sought bids from private equity and trading firms for the whole of Nissan Trading and a buyer would be selected by October, Bloomberg said, citing sources "familiar with the matter".

The sale process for the unit was ongoing and no agreements had been reached yet, reports said.

Nissan did not immediately respond to a Reuters news agency request for comment.

Japanese automotive components manufacturer Marelli Corporation this week announced a reorganisation of its production bases in Japan, including the closure of four manufacturing facilities, mainly in response to weak demand from key vehicle manufacturing affiliate Nissan Motor.

Marelli said the changes were part of its "ongoing strategy to ensure its operations are structured in a way that can best respond to the significant changes within the global and domestic automotive industry".
