r/PriusC

Good evening, I drive a 2013 Toyota Prius. When I push in the pedal and it shows the green key icon on the screen, and I push the start button, most of the time my car starts fritzing out (spelling Ik :( ) and i have to disengage the pedal, repress it and let it make this long like buzzing/machine noise in the front, then push the button when it’s done making the noise and THEN it will turn on normally. I’m attaching a video to see if anyone knows what this is or is familiar with it. It won’t let me put 2 videos, but the second one it’s the car popping up the “P” for park and it appears and disappears and makes almost like a “blinker” noise but I can hear the car trying to engage something?

New to me 2014 Prius C, started having intermittent keyfob and starting issues so I figured the 12v was failing

Got a replacement and got down there... and saw this little situation going on with the negative cord which im sure wasn't/isn't helping anything lol

Never replaced a battery terminal before but watched a few videos and it looks fairly easy so I guess that's what I'm doing tomorrow!

Anyone got recommendations for screws for this. Look barely holds

Any any recommendations to fix this. Got a new mount but nount points are broken so previous owner looks like they glued it together but broke again
