EnlargeKyodo via APToyota Prius models come off a Japanese assembly line in June 2009. Toyota officials said Wednesday that the company has received dozens of complaints involving the brakes in the latest Prius model
Transportation Secretary Ray LaHood is telling owners of millions of recalled Toyota vehicles with gas pedal problems to stop driving them and get them fixed. The warning comes amid reports of complaints in the U.S. and Japan about brake problems with the popular Prius hybrid and a U.S. government investigation of potential electrical problems in Toyota vehicles. LaHood's warning came Wednesday in testimony before a House appropriations subcommittee on transportation. LaHood says his advice to owners is to "stop driving it. Take it to a Toyota dealer because they believe they have a fix for it."
Toyota's most recent recall in the United States affects 2.3 million vehicles with the potential for sticking gas pedals.
In addition, Toyota has been hit by over 100 complaints in the U.S. and Japan about brake problems with the Prius, the latest in a spate of quality troubles for the automaker as it grapples with massive global recalls.
LaHood said he plans to speak with Toyota President Akio Toyoda about the automaker's spate of recalls in the United States. LaHood said Wednesday he will call Toyoda in the coming days to make sure the Japanese automaker is aware of the government's concerns about safety issues with Toyota vehicles.
The secretary said the National Highway Traffic Safety Administration will conduct an investigation into electronic throttle control systems and potential electromagnetic interference in the nation's fleet of vehicles.
LaHood said the government "has the resources" to conduct the investigation.
The Japanese company's sales are being battered in the U.S. — Toyota's biggest market — after recalls of top-selling models to fix a gas pedal that can stick in the depressed position.
The new Prius gas-electric hybrid, which went on sale in Japan and the U.S. in May 2009, is not part of the recalls that extend to Europe and China, covering nearly 4.5 million vehicles.
The U.S. National Highway Traffic Safety Administration has received about 100 complaints involving the brakes of the new Prius model. Two involved crashes resulting in injuries.
Japan's Transport Ministry said Wednesday it has also received 14 complaints since July last year about brake problems with Toyota's new Prius hybrid.
The 14 complaints included an accident in July 2009, in which a Prius crashed head on into another car at an intersection. Transport Ministry official Masaya Ota said two people were slightly injured in the accident.
"The Prius driver in the accident told police that a brake did not work," Ota said. "Other Prius drivers also complained brakes were not so sharp." The complaints in Japan involve the new Prius model, and the vehicles were all made in Japan, he said.
The ministry ordered Toyota, the world's No. 1 automaker, to investigate the complaints. The other 13 cases happened from December to January 2010. Ota said the ministry has yet to receive a formal report on the complaints from Toyota.
Toyota spokeswoman Ririko Takeuchi said the company has received reports about the Prius complaints in North America and in Japan and was now looking into the matter.
Toyota shares plunged 5.7 percent to 3,400 yen ($38) with jittery investors dumping stocks in the wake of the Prius woes in the U.S. and Japan. The benchmark Nikkei stock index edged up just 0.3 percent to 10,404.33 as the drop in Toyota dampened sentiment.
"Investors were worried the latest trouble involving the Prius could get bigger. The problem could pose a bigger question on Toyota's quality and safety," said Kazuhiro Takahashi, market analyst at Daiwa Securities SMBC Co. Ltd.
Also Wednesday, the South Korean government said Toyota's local unit was recalling 444 vehicles over defects in gas pedals and floor mats.
The vehicles were made in North America, and the more than 19,000 Toyota vehicles imported from Japan weren't part of the recall, the Ministry of Land, Transport and Maritime Affairs said in a statement.
Toyota is facing growing criticism that it has not done enough to ensure the safety of its vehicles. LaHood told The Associated Press Tuesday that federal officials had to alert Toyota to the seriousness of the safety issues that eventually led to the recalls.
"They should have taken it seriously from the very beginning when we first started discussing it with them," he said. "Maybe they were a little safety deaf."
LaHood also said the U.S. government was considering civil penalties for Toyota for having dragged its feet on safety concerns.
Toyota Executive Vice President Shinichi Sasaki acknowledged Tuesday in a Nagoya, Japan, news conference that it took prodding from NHTSA officials for the company to decide on the U.S. recall.
Toyota has long prided itself on sterling vehicle quality and assembly line methods that empowered workers to ensure faultless production.
The latest recall, announced Jan. 21, over sticky gas pedals affects 2.3 million vehicles in the U.S. alone.
Any serious problems emerging in the Prius, Toyota's flagship green car model, is certain to further tarnish its brand.
