Toyota plans to replace the gas pedals on 4 million vehicles in the United States because the pedals can get stuck in the floor mats and cause sudden acceleration, a flaw that led to the sixth-largest recall ever in the U.S.
The repairs are a critical step to restoring the reputation of the world's biggest automaker, which suffered a blow when the recall was announced in September after years of making safe, reliable cars and trucks.
In plans outlined Wednesday, dealers will offer to shorten the length of the gas pedals by three-fourths of an inch beginning in January as a stopgap measure while the company develops replacement pedals. New pedals will be installed by dealers on a rolling basis beginning in April, and some vehicles will get a brake override system as a precaution.
The massive recall is the largest in the U.S. for Toyota Motor Corp. The Japanese automaker had earlier told owners to remove the driver's side floor mats to keep the gas pedal from becoming jammed.
Popular vehicles such as the midsize Camry, the top-selling car in America, and the Prius, the best-selling gas-electric hybrid, are among those to be fixed. The recall also includes the luxury Lexus ES350, the vehicle involved a fiery fatal accident in California that focused public attention on the danger.
Spokesman Irv Miller said Toyota is "very, very confident that we have addressed this issue." Toyota has no reason to believe that there are problems with the cars' electronic control systems, he said. An electronic-control malfunction also could cause unintended acceleration.
Toyota officials said the floor mats are only sold in the U.S., and the recall would be limited to North America.
Toyota would not say how much the repairs would cost, but analysts expected them to be extremely expensive because of the work involved and the manufacturing of new pedals. Toyota also said it would provide newly designed replacement floor mats.
