Mazda Motor Corp. said Thursday it has found no problem with its CX-5 sport utility vehicle through its joint investigation with police into an accident during a test drive last month.

During the drive on Nov. 10 to test the vehicle's automatic brake system in Saitama, the vehicle failed to stop in front of a mat and collided with a chain-link fence, injuring its driver and a Mazda representative in the front passenger seat.

Local police sources said the vehicle's automatic brake system is designed to work at a speed of 30 kph or less when the accelerator is not pressed and that the accident may be attributable to some human error.

Mazda said it will continue its voluntary suspension of test drive campaigns.
