The Japan Automobile Manufacturers Association on Tuesday compiled a report on the industry's responses to consumer complaints in an effort to regain trust in the wake of last summer's scandal in which Mitsubishi Motors Corp. admitted to covering up complaints for decades.

The report -- submitted to the Land, Infrastructure and Transport Ministry -- calls on management to clarify the roles of those responsible for handling consumer complaints.

It also says company executives should establish a clear and thorough system for the entire process, from receiving consumer complaints, checking the alleged faults as well as their judgments on the cases in question.
