Car not on ticking sound from engine

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your TSX. While the car is off, a rapid ticking sound from the engine area could indicate a few things. Most commonly, it suggests that the battery is weak or failing, leading to insufficient power to the electrical components. This could cause the ticking noise as relays or the starter engage without enough power to function correctly. The flickering blue light near the rearview mirror may be related to an electrical system or security feature, which can sometimes activate when the battery voltage is low. It's a good idea to start by checking the battery connections and testing the battery itself. If the battery is fine, there may be an underlying electrical issue that needs further investigation. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
