Why do your fans turn on randomly as your Toyota rav 4 is parked?

The fans in your Toyota RAV4 may turn on randomly while parked due to the engine's cooling system working to maintain optimal temperatures. This can happen if the engine was recently used and is still hot, prompting the fans to activate even after the vehicle is turned off. Additionally, some models have features that allow the fans to run to cool down components like the engine or transmission, or they may activate due to a faulty temperature sensor or electrical issue. If the behavior persists or seems abnormal, it may be best to consult a mechanic for a thorough inspection.
