In related news, the U.S. National Highway Traffic Safety Administration (NHTSA) has launched an investigation after 163 Toyota Corolla owners complained of unintended acceleration -- similar to a flaw that led to a recall of 10 million Toyotas in 2009. This time, as many as 1.69 million Corollas from 2006-2011 are under scrutiny.
