(USA TODAY) -- General Motors' four new recalls announced Friday of nearly 600,000 cars worldwide includes a recall of its Chevy Camaro for an ignition switch that can inadvertently be bumped by a shorter driver's knee out of the run position, shutting off the engine.
The recall of 464,712 of Chevy's 2010-14 Camaros in the U.S. -- 511,528 worldwide -- is not related to the massive switch recall earlier this year, which involved the internal ignition switch mechanism, but the effect of being bumped out of the "run" position would be the same for the car and driver.
The company said the the problem was found in GM testing and that it knows of three crashes and four injuries related to the problem.
The fix will be to exchange the current combined key and remote fob, in which the key flips out of the fob, for a new design in which the key and fob are separate.
The three additional recalls -- 65,121 cars in the U.S. and 69,839 worldwide:
• Saab 9-3 convertible: 28,789 in the U.S. from the 2004-2011 model years for a driver's-side seat belt cable that could break and cause the belt to fail. No crashes or injuries.
• Chevrolet Sonic: 21,567 in the U.S. from the 2012 model year. Cars with the base 1.8-liter engine and the six-speed automatic for a transmission turbine shaft that could break and limit the transmission to first or second gear. If it was in a higher gear at the time, the car would coast until it was going slow enough for second gear. No crashes or injuries.
• Buick LaCrosse: 14,765 in the U.S. from the 2014 model year wiring in the driver's door could corrode, causing the power windows and sunroof to continue to work. The defect is likely more of a theft risk than a safety problem, and GM knows of no crashes or injuries.
