Toyota Motors says its massive recall of vehicles could cost it up to $US2 billion in lost output and sales.
The company is in the process of recalling millions of vehicles that are potentially prone to uncontrolled acceleration.
Toyota said the checks might spread from the United States and Europe to include the Middle East, Latin America and Africa.
The company said 180,000 potentially affected cars have been sold in these regions.
The BBC reports Toyota has identified eight models as potentially at risk, but stresses that very few are actually faulty.
Recall details
Last week, Toyota, recalled up to 1.8 million cars across Europe following a fault which meant the accelerator pedal potentially could stick.
It has also recalled 2.3 million cars in the United States in the past four months for the same problem.
Separately, the company has also recalled more than five million vehicles in the US for another problem, in which the accelerator pedal can get trapped under the floor mat.
The models suspected of having defects include the Yaris, the Corolla and the RAV4 sports utility vehicle.
