Toyota is considering a recall of its top-selling Corolla after complaints about power steering problems in another blow to a company already reeling from a string of safety problems.
Executive in charge of quality control Shinichi Sasaki said it was taking seriously the complaints about power-steering problems in the Corolla, the world's best-selling car.
He said drivers may perceive a strange feeling as though they were losing control over the steering, but it was unclear whether the problem was with the braking system or a problem with the tyres.
There have been fewer than 100 complaints.
He said it was still uncertain if a recall would be necessary but the company is considering one. The number of affected vehicles is unclear.
The company was putting customers first in a renewed effort to salvage its reputation and would do whatever is necessary if a fix is needed, Mr Sasaki said.
Toyota has recalled 8.5 million vehicles globally during the past four months because of problems with sticking accelerator pedals, floor mats trapping accelerators and faulty brake programming.
Toyota reiterated its promise to put customers first in beefing up quality controls. It promised a brake-override system in all future models worldwide that will add a safety measure against acceleration problems that are behind the recent massive recalls.
"We are not covering up anything, and we are not running away from anything," chief executive Akio Toyoda said.
Toyota has also commissioned an independent research organisation to test its electronic throttle system, and will release the findings as they become available.
