WASHINGTON -- Toyota faced mounting pressure Thursday as the government opened a probe of brake problems with the Prius, a crown jewel of its lineup. The beleaguered automaker said it was "too soon" to decide whether to add the hybrid to the millions of cars it has recalled.
Some owners of the 2010 Prius have reported their brakes do not always engage immediately when they press the brake pedal, or that the brakes have an inconsistent feel. The National Highway Traffic Safety Administration said it would assess the scope of the problem and the safety risk to about 37,000 cars that could be affected.
The investigation comes as safety questions surround Toyota, which has already issued broad recalls for millions of its best-selling vehicles, including the Corolla and Camry, because of gas pedals that can become stuck.
U.S. officials have blessed Toyota's solution to that problem, a small piece of steel designed to eliminate excess friction in the pedal mechanism, but have criticized Toyota for being too slow in responding to customer complaints.
Asked whether Toyota would recall the 2010 Prius, spokesman Brian Lyons said: "It's too soon to call at this point. We will, of course, fully cooperate with NHTSA in that investigation."
Japan's top business daily Nihon Keizai, however, reported today that Toyota will recall 270,000 of the 2010 model Prius in the United States and Japan. But an official at Japan's transport ministry said the government has yet to receive a recall notice from the carmaker.
A Toyota spokeswoman in Tokyo also said there was no decision yet on whether to recall the Prius but said the company is investigating possible brake problems with its luxury Lexus hybrid, which uses the same brake system as the Prius. Toyota has not received any complaints about the Lexus HS250h and the probe is to ensure safety, spokeswoman Ririko Takeuchi said.
Congressional investigators expanded their review of Toyota to include the Prius as California Rep. Darrell Issa, the ranking Republican on the House Oversight Committee, asked Toyota for records on its Prius brakes.
The committee plans a hearing next week on Toyota's recalls, the first of two in Congress this month. Issa said he would focus on whether Toyota or NHTSA failed to properly deal with safety complaints or address them quickly enough.
"We think they should have acted more aggressively or quickly," said Issa, who owns four Priuses, none of which fall under the investigation.
Connecticut Attorney General Richard Blumenthal said he and attorneys general in other states may take legal action against Toyota over possible deceptive claims to consumers about the safety of the company's cars.
"Typically, on an issue of this magnitude and impact, we might well join forces," Blumenthal, a Democrat running to succeed retiring Sen. Chris Dodd, said in an interview.
Toyota said some customers have complained of an inconsistent feel during slow and steady application of brakes on rough or slick roads when the antilock brakes engage. Normally, the brakes grab and release rapidly in reaction to slipping tires.
Paul Nolasco, a Toyota spokesman in Japan, said the time lag drivers feel before brakes kick in stems from the two systems in a gas-electric hybrid -- the gas-engine and the electric motor. The brakes work if the driver keeps pushing the pedal, he said.
NHTSA said some Prius owners reported a "brief lag" or "brief surge" when they used the brakes. The agency did not specify how long those lags were. At highway speeds, a car can travel nearly 100 feet in just one second.
Toyota said it has received 180 reports of problems with Prius brakes in Japan and the United States. The problem is suspected in four crashes resulting in two minor injuries, according to a NHTSA preliminary safety report.
