IV. Background

On certain 2010 model year Corolla and Corolla Matrix vehicles equipped with the 2ZR-FE engine, that are assembled in North America, the engine accessory belt may have been improperly manufactured. On a small number of these vehicles, there is a possibility that the belt may prematurely deteriorate and detach from the pulleys. This condition will cause abnormal noises from the engine compartment as well as illumination of the Malfunction Indicator Light (MIL) and/or charging system warning light. If the vehicle is continually operated under this condition, the engine may overheat.
