General Motors is recalling more cars for problems with ignition switches.
GM is recalling nearly 512,000 Chevrolet Camaro muscle cars from the 2010 to 2014 model years, built in Canada at a GM assembly plant in Oshawa, Ont.
The automaker says 17,736 of the Camaros are in Canada. A driver's knee can bump the key and knock the switch out of the "run'' position, causing an engine stall.
That knocks out power steering and brakes and could cause drivers to lose control.
GM says it knows of three crashes and four minor injuries from the problem.
GM says the Camaro switches met its specifications, unlike the switches at the centre of a recall of 2.6 million small cars. That problem has caused more than 50 crashes and at least 13 deaths.
The Camaro key is concealed in the Fob like a switchblade. GM will replace it with a straight design.
