Toyota Motor Co., still in recovery mode after a series of problems that plagued its global operations over the last three years, announced Wednesday it is recalling 2.5 million vehicles sold in the United States due to a potential risk of fire. The recall involves 7.43 million vehicles worldwide sold under the Toyota and Scion brands. This is the largest safety-related service action the maker has announced since it began a series of recalls related to the risk of unintended acceleration in late 2009. That and other safety issues led Toyota to recall 14 million vehicles in 2009 and 2010. Read the full story at NBC News.
