General Motors is recalling more than half a million Chevrolet Camaros because of the danger that a bump to the keys could suddenly turn off the ignition — a problem similar to the defect that led the automaker to recall millions of small cars this year.
G.M. said that a driver’s knee could jostle the key fob, causing the ignition to turn off and cutting the engine. The automaker said it was aware of three crashes and four injuries related to the defect, which is in about 510,000 Camaros worldwide from the 2010 to 2014 model years.
