Toyota has now recalled more than 14 million vehicles globally to fix gas pedals and other safety problems since 2009. U.S. regulators said earlier this month that electronic flaws were not to blame for reports of sudden, unintended acceleration. The company paid the U.S. government a record $48.8 million in fines for its handling of three recalls.

The world’s No. 1 auto company said more than half of the vehicles under recall were being added to a massive 2009 recall that fixed gas pedals getting trapped in the floor mat.

The Japanese automaker said it would add three models to the 2009 pedal entrapment recall: about 600,000 4Runner SUVs from the 2003-2009 model years; 761,000 RAV4 compact SUVs from the 2006-2010 model years; and 17,000 Lexus LX 570s from the 2008-2011 model years.

The recall also includes 372,000 RX 330, RX 350 and RX 400H vehicles from the 2004 through early 2007 model years and 397,000 2004-2006 Toyota Highlander SUVs and hybrid versions to replace floor carpet covering and retention clips on the driver’s side that could interfere with the accelerator pedal arm.

Toyota also recalled 20,000 2006 through early 2007 GS 300 and GS 350 all-wheel drive vehicles to change the shape of a plastic pad embedded in the driver’s side floor carpet that could cause pedal interference.

Toyota spokesman Brian Lyons said the company was unaware of any accidents or injuries related to the new recalls.

“We enlisted the best and brightest engineers to study Toyota’s electronics systems and the verdict is in. There is no electronic-based cause for unintended acceleration in Toyotas,” Transportation Secretary Ray LaHood said in a statement.

Toyota has recalled more than 12 million vehicles globally since fall 2009 to address sticking accelerator pedals, gas pedals that became trapped in floor mats, and other safety issues. The recalls have posed a major challenge for the world’s No. 1 automaker, which has scrambled to protect its reputation for safety and reliability.

Toyota did not immediately comment on the report. Shares of the automaker climbed on the New York Stock Exchange following the news. Toyota shares were up more than 4 percent, to 89.00 in mid-afternoon trading.

Toyota paid the U.S. government a record $48.8 million in fines for its handling of three recalls. The company has said it has not found any flaws in its electronic throttle control systems and said the previously announced recalls have addressed the safety concerns.

LaHood said NASA engineers “rigorously examined” nine Toyotas driven by consumers who complained of unintended acceleration. NASA reviewed 280,000 lines of software code to look for flaws that could cause the acceleration. Investigators tested mechanical components in Toyotas that could lead to the problem and bombarded vehicles with electro-magnetic radiation to see whether it could make the electronics cause the cars to speed up.

A preliminary part of the study, released last August, failed to find any electronic flaws based on a review of event data recorders, or vehicle black boxes.

Despite its findings, LaHood said the National Highway Traffic Safety Administration was considering new regulations to improve safety. They include requiring brake override systems on all vehicles, standardizing keyless ignition systems and requiring event data recorders, or vehicle black boxes, on all new vehicles.

Transportation officials said they would also consider conducting more research on electronic control systems and review the placement and design of accelerator and brake pedals.

In Tokyo on Tuesday, Toyota reported a 39 percent slide in quarterly profit but raised its full-year forecasts for earnings and car sales. It is a mixed picture for the automaker, which is enjoying booming sales in high-growth markets in Asia, Africa and South America, while facing lingering worries about quality lapses in the U.S.

In addition to the recalls, Toyota began installing brake override systems on new vehicles. The systems automatically cut the throttle when the brake and gas pedals are applied at the same time. The company also created engineering teams to examine vehicles that are the subject of consumer complaints and appointed a chief quality officer for North America amid complaints its U.S. division did not play a large enough role in making safety decisions.

Consumer advocates and safety groups raised concerns that flawed electronics could be causing unwanted acceleration in the Toyotas. They have questioned the reliability of the event data recorders studied by the government, saying they could be faulty or fail to tell the whole story of the individual crashes.

Toyota’s safety issues received broad attention from the government after four people were killed in a high-speed crash involving a Lexus near San Diego in August 2009.

NHTSA has received about 3,000 reports of sudden acceleration incidents involving Toyota vehicles during the past decade, including allegations of 93 deaths. NHTSA, however, has confirmed just five of them.

Congress considered sweeping safety legislation last year that would have required brake override systems, raised penalties on auto companies that evade safety recalls and given the government the power to quickly recall vehicles. But the bills failed to win enough support, and it remains unclear if Congress will pursue similar legislation before the 2012 elections.

The National Academy of Sciences is conducting a separate study of unintended acceleration in cars and trucks across the auto industry. The panel is expected to release its findings this fall.
