Official summary
Service campaign - ro3 - toyota has determined that an unused wire harness connector on certain subject model sedans operating in cold weather conditions can experience an electrical short circuit due to salt contamination. When salt water or snow is carried into the vehicle by the driver's shoes it can saturate the carpet and contaminate a wire harness connector which may be located under the carpet near the driver's left foot. If this occurs, the connector could heat up and in extreme cases, result in fire. To correct this condition, dealers will modify the wire harness. *tw
