(MENAFN) General Motors Co. started recalling 511,528 Chevrolet Camaros vehicles over an ignition switch defect, which is similar to the defect linked to at least 13 deaths in Chevrolet Cobalts, The Peninsula Qatar reported. The US-based automaker said it was aware of a smaller accidents caused by the sporty two-door car defect, Camaro, but not death cases. It said the Camaro switch defect differed from the problem in the Cobalts, but a consumer advocate said GM still should have recalled the Camaros sooner. "It is troubling that GM continues to announce ignition switch-related recalls on late-model vehicles (which) raises questions about how pervasive the problem is," said the senior Democrat on the House Energy and Commerce Committee that is investigating GM.
