Car Doesn't Start With First Press of Power Button

Hi all,

My car isn't starting with the first press of the power button. Generally, what I am noticing is that the locks sound weaker when the car is opening. I press the power button and usually the lights on the dash will come on, but the screen (GPS, etc.) and the display for the climate control may not. Usually, if I press the power button multiple times, the car will eventually power on. If the park break was on and I take it off while trying to start the car, that usually helps.

Lately, if it is taking a very long time for the car to start, I get a hybrid system overheating warning. I have only seen this twice. I'm unsure if that is actually related to the hybrid coolant or not. I never see this message when driving the car.

Is this a simple 12 volt battery issue or is it something more serious?

Another Prius driver said something about a recall update to the car that may be causing the inverter to do something that isn't giving the car enough power. I don't really understand what he was talking about. I just know that the last time I went to the dealership during the summer with a problem (A/C compressor burnt out), they tried to take me for a ride, so any help with the diagnostics would be greatly appreciated!

 

Okay, thank you so much!
