A housewife filed a lawsuit Friday against Mitsubishi Motors Corp. over its coverup of a defect in the braking system of a car she drove, demanding 6.8 million yen in compensation for "mental pain" she suffered from a crash linked to the defect.

The 37-year-old Kumamoto woman, who was not named, filed the suit with the Kumamoto District Court. She is seeking damages for the shock she suffered due to the accident last June, in which she crashed into another car while driving a Pajero in the city after the brakes failed.

In the accident, two men in the other car suffered neck and other injuries that required two weeks to heal and the front of the Pajero was damaged, the suit said.

The woman has suffered insomnia and has been unable to drive due to the emotional shock since the accident, the lawsuit said.
