The amount of adhesive applied between the inner and outer parts of the crankshaft pulley may be inadequate. If this is the case, the outer ring may become misaligned and/or not properly rotate with the inner ring, causing an abnormal noise and/or illumination of the Check Engine Light. In some cases, the power steering belt could come off resulting in a loss of power steering assist, increasing the risk of a crash. Dealers will inspect the crankshaft pulley and replace it if necessary.
