TOYOTA issued a recall on the AVALON, ES 350, and ES 300H models

On certain vehicles equipped with Pre-Collision System (PCS), the system could unexpectedly activate while operating the vehicle. Under certain situations, the system may interpret a steel joint or plate in the roadway as an obstacle, and the system may apply the service brake automatically. If the PCS applies unexpected braking force during normal vehicle operation when no impending collision object is present, it could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will disable the Pre-Collision System (PCS) as an interim measure, and when parts become available, will replace the PCS components with improved parts.
