The IMA light is on.
The IMA module would need to be tested to see if code P0A7F is in system. If it is, then the IMA module may need to be reprogrammed. Code P0A7F is most typically related to a battery issue in hybrid cars. If a different code is retrieved, then normal diagnostics would be followed. For this year of the vehicle, you may have a battery that is getting weak and not performing as good as it should be. I recommend having a certified mechanic, such as one from YourMechanic, test the vehicle's IMA module and replace the battery if needed.
