Toyota has told Japan's government it will recall Prius hybrid vehicles worldwide, a transport ministry official says.
Toyota is recalling its popular Prius and two other hybrid models in Japan to fix faulty brakes, plunging the auto giant deeper into crisis as lawsuits in the United States pile up.
Toyota, facing a barrage of complaints ranging from unintended acceleration to brake failure, is scrambling to reassure drivers it did not sacrifice its legendary safety in its successful drive to be the world's largest automaker.
The company filed a recall in Japan on Tuesday covering the regular Prius and its plug-in version, as well as the Sai sedan and the luxury Lexus HS250h.
About 223,000 hybrid cars will be recalled in Japan - covering the models that went on sale last year, documents show.
There have been about 200 complaints in Japan and the US about a delay when the brakes were pressed in some conditions.
Toyota is yet to reveal whether the recall will affect overseas markets.
But the official in the Japanese transport ministry said they had been told that Toyota would take the same measures world-wide.
Company president Akio Toyoda is scheduled to address the Prius issue at 0630 GMT (1730 AEDT) in only his second news conference since the overall recall crisis went global nearly two weeks ago.
The company's troubles escalated with a new lawsuit in the United States failed by a California woman who alleges her Prius has severe braking problems which make it dangerous to drive.
Lawyers for the plaintiff are pursuing what is believed to be the first class-action lawsuit over the faulty Prius brakes, which would add to legal trouble facing Toyota over the accelerator problems.
The Japanese maker has said it redesigned the anti-lock braking system for Prius cars produced since last month.
It says a delay occurs when the vehicle switches to the conventional hydraulic brake from regenerative braking, used by hybrids to capture the energy of the car's motion to recharge the battery for its electric motor.
Customers have reported problems with the braking when driving at slow speeds, on slippery roads, or over potholes and bumps, Jim Lentz, president of Toyota's US sales arm, said in an interview with news-sharing website Digg.com.
"Exactly what the solution's going to be I can't tell you but I can assure you that we're going to do whatever's necessary," he said.
"We are working on a solution and we hope to have a solution for that very soon."
The group has denied it was slow to act on the safety problems. Lentz said the company received a report of a sticky gas pedal on a Tundra pick-up truck in 2007 but was unable to pinpoint the cause.
The accelerator problems have been blamed for several accidents, including one in California in August in which four family members were killed.
Toyota said it had resumed production in North America of several models whose sales were suspended over the accelerator issue.
But Toyota will halt production of the Sai and Lexus HS250h hybrids for at least one week in Japan due to the brake problems, and may also suspend sales of the models, the Nikkei business daily reported.
The trouble comes on top of recalls of more than eight million vehicles worldwide due to sticking gas pedals that have severely dented the image of the company, which overtook General Motors in 2008 to become world number one.
The recalls affect more than Toyota's entire 2009 global sales of 7.8 million vehicles.
