Check the voltage on the starter battery in the front. It is used to start the car only. The rear battery is much larger and supports all the electrical needs of the car.
If your starter battery upfront does not show 12.0 volts, try a charger. It is also possible that your alternator is not putting out enough juice to keep that starter battery fresh. Once she starts, the starter battery should show a slow return to 14.0 volts or more. You might charge the starter battery fully, and then take a voltage measurement the following morning. You should still have 12.0 volts from that battery.
Please measure and report back what you find.

@V12Kid - did you fix the issue? What was it?
I was able to replace the battery myself but my local shop replaced the starter. Good to go now
