    If left for 4 months the main battery unit may need to be recharged which, I believe, is dealer job.

    Yes the hybrid battery. Unfortunately, leaving new Aux battery connected will never charge up the hybrid battery. As far as I recall, Toyota suggest 2 months without starting is enough to deplete the hybrid battery.

    Measure the voltage of the new 12V battery when the car is IG-OFF, and post. Make sure the connections are tight, including the negative battery cable where it bolts to the body.

    Time then, to tow your car to your local Toyota dealer for help.

    Or obtain Mini VCI and obtain the DTC that have been logged, maybe that will provide a clue about what is wrong.
