Toyota admits brake software problem

US authorities have ordered a probe into reported braking problems affecting new Toyota Prius vehicles.



The carmaker Toyota has admitted a software problem in the new Prius\'s brakes, but says it has now been fixed.



The admission follows worldwide recalls of almost eight million cars due to floor mat and pedal problems.



Toyota\'s managing officer, Hiroyuki Yokoyama, says the company had found a clash between the anti-lock brake system (ABS) and regenerative braking.



However, he says more investigation needs to be done before deciding on whether to issue a recall on the Prius.
