WASHINGTON, D.C. --- General Motors is recalling 1.49 million vehicles because of a potential condition in which drops of engine oil may be deposited on the exhaust manifold through hard braking.
If the manifold is hot enough and the oil runs below the heat shield, it may ignite into a small flame and spread to the plastic spark plug wire channel and beyond, according to the National Highway Traffic Safety Administration website. This increases the risk of an engine compartment fire.
