2012 Plug in battery problems. Car wont unlock on full charge. Won’t show actual charge mileage.

I have tried looking around here but no one seems to have this issue. I have been having issues with my battery and the charging system. I plug it in and some nights it will charge and some nights it wont. I always check the plug and make sure everything is connected fully and charging when i leave. Sometimes i have to plug it in a few times because the light will turn off after a few seconds. There is also many times where i come to the car and try to unlock it by putting my hand in the handle. The car half beeps and half unlocks. The doors don’t open but the locks jiggle and the car half beeps a few more times. Sometimes pressing the button on the key opens it no sometimes i use the actual key and the car works fine when i get in. There is also times when I try to turn to car on and the car turns on but not the engine. I have to try a few times and then it works and it will have charge even. Sometimes ill drive away with no charge and half way down my hill i have 7 miles. What is happening?? I have switched batteries and even did the recall that involved the battery.
