The Japanese carmaker said it is investigating reports of a problem with the power-steering system of the Corolla and may order certain of those vehicles to dealerships to address the issue, if needed. Toyota said there were fewer than 100 problems reported with the Corollas.
At a news conference Wednesday in Tokyo, Toyota President Akio Toyoda said the company was also planning a brake-override system to be installed on its new vehicles.
Toyota has recalled more than 8 million vehicles because of various issues, including floor mats, accelerators and brakes.
Those problems led the U.S. Congress to order a hearing into the series of recalls. Toyoda said he wouldn't attend the hearing next week but said the company would cooperate with investigations into possible safety issues and denied any corporate coverup of the problems.
