Toyota Motor Corporation announced it would recall 3.8 million vehicles in the United States — the company’s largest ever U.S. recall — to address problems with a removable floor mat that could cause accelerators to get stuck and lead to a crash. The recall involves popular models such as the Toyota Camry, the top-selling passenger car in America, and the Toyota Prius, the best-selling gas-electric hybrid. Toyota said owners could be notified about the recall as early as next week. Toyota spokesman Irv Miller said until the company finds a fix, owners should take out the removable floor mat on the driver’s side and not replace it. A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop a vehicle, which could cause a crash, serious injury or death. The Toyota models being recalled include the 2007-2010 Camry, 2005-2010 Avalon, 2004-2009 Prius, 2005-2010 Tacoma and 2007-2010 Tundra. The Lexus models facing the safety recall are the 2007-2010 ES 350 and the 2006-2010 IS 250 and IS 350.
