There is a possibility that the outer ring of the crankshaft pulley may become misaligned with the inner ring, causing noise and/or illumination of the discharge warning light. If this condition is not corrected, the belt for the power steering pump may become detached from the pulley and the driver may notice a sudden increase in steering effort. There are no reports of accidents or injuries related to this condition.
The vehicles involved are certain:
No other Toyota or Lexus vehicles or these Toyota models with 4 cylinder engines are involved.
Toyota is currently working on obtaining the necessary replacement parts. Once the replacement parts have been produced in sufficient quantities, Toyota will send an owner notification by first class mail advising owners to make an appointment with an authorized Toyota or Lexus dealer to have the crankshaft pulley inspected and if necessary, replaced at no charge. The owner notifications will be mailed by first class mail beginning in January, 2012.
In the meantime, if an abnormal noise is heard coming from the engine compartment, the owner is asked to make an appointment with any Toyota or Lexus dealer to have the vehicle inspected for this condition.
