Toyota started a global recall over engine defects in its Lexus and Crown models, moving to repair more than 95,000 vehicles in Japan and South Korea over the latest trouble for the automaker beset with quality problems.

Toyota Motor Corp. had said on Friday that 270,000 cars worldwide would be recalled to replace valve springs, crucial engine components that are flawed in the recalled vehicles and could make them stall while in motion.

The total includes 138,000 vehicles in the U.S., 91,903 in Japan, 15,000 in Europe, 10,000 in the Middle East, 6,000 in China, 4,000 in Canada, and 8,000 elsewhere. South Korea's Transport Ministry said on Tuesday that 3,704 vehicles would be recalled there.

"We apologize for inconveniencing our customers. We hope to fix the problem soon," company spokesman Paul Nolasco said in a statement.

Complaints adding up

Toyota has received about 200 complaints, but no accidents due to the defects have been reported. Officials have blamed the problem on a foreign substance being introduced during manufacturing of the valve springs.

Toyota said it is replacing the valve spring in the recalled vehicles, produced between July 2005 and August 2008 — Lexus models GS350, GS450h, GS460, IS350, LS460, LS600h, LS600hL and Crown models. Vehicles from the 2009 and 2010 model years are not affected.

Faulty past

The quality problem affecting top-of-the-line products comes as Toyota struggles to move on from massive global recalls that started in October. More than 8.5 million vehicles already have been recalled for various problems, including sticking gas pedals, braking software glitches and defective floor mats.

The world's top automaker was fined a record $16.4 million in the United States for responding too slowly when the recall crisis erupted.

Trusting Toyota

The latest woes come on top of a recall last week for 17,000 Lexus hybrids after testing showed fuel can spill during a rear-end crash. Analysts say the latest recalls do little to instill consumer confidence after Toyota President Akio Toyoda apologized to shareholders last month and vowed to improve vehicle quality inspections.

"It is not doing a good job in communicating a message about what exactly it is doing to beef up quality checks," said Shotaro Noguchi, auto analyst with Nomura Securities Co. in Tokyo. "So it is hard for people to believe Toyota is taking the customer's view as it is promising to do."

Toyota faces more than 200 lawsuits in the U.S. tied to accidents involving defective automobiles, the lower resale value of Toyota vehicles, and a drop in its stock value. The company's overall sales have been hurting this year following its safety-related recalls. Toyota has been trying to boost U.S. sales with deep promotions, including zero-percent financing and free maintenance.

The Tokyo market reacted with calm to Toyota's recall news. Toyota shares gained 0.5 percent to finish at 3,035 yen.
