RepairPal Expert Overview
A problem may develop with the crankshaft pulley. This could result in an abnormal noise, illumination of the Check Engine Light, and/or loss of power steering assist.
Toyota will notify owners of affected vehicles beginning in January 2012. If you are experiencing an abnormal engine noise, illumination of the Check Engine Light, and/or loss or power steering, or you don't receive notification and you feel you should have, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call.
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.
