2018 Chrysler Pacifica wouldn’t start, brake pedal went to the floor

Had the radio on about 30-45 minutes listening to drive in Church. Tried to start vehicle and nothing happened , except brake pedal went all way to floor. Tried several times…same result. Let it set for about 5 minutes and it started when I tried.

I suspect that you drained the battery if you had the radio on for so long without starting the engine.You need a recharge.
