The power port is most likely a blown fuse. The 2.4 is direct injection, you can tell due to the throttle body being at the bottom of the engine. Has the throttle body been cleaned?
I have a couple of questions if you dont mind me asking. 1. Do you hear a weird buzzing/humming sound coming from the engine bay, specifically coming from above the front driver side wheel inside the engine bay when unlocking the car when its cold (Like in the morning before going to work after the car sat all night). I can also hear humming/buzzing sound coming from the brake pedal when I depress it when the car is off too. 2. Are your brakes really touchy/sensitive? On mine, the brake lights activate when the brake pedal is like pushed a hair down, if not even less. And the car starts slowing down as soon as you tap the brakes very lightly. 3. Have you ever had to deal with the wrench symbol on the dash? It lights up sometimes and goes away when restarting the car, but if i keep driving with it the hybrid system warning light comes on with the check engine light on. When I hooked up obd scanner, no codes popped up so I just erased it. For reference the car sat for a whole year without ever being started once which caused the 12v battery to be damaged, not even considering the fact that the 12v battery is also 6 years old. Could the 12v battery be the cause of the wrench light popping up and triggering the hybrid system warning on the dash? Oh I forgot to mention I own a 2012 sonata hybrid with 100k miles. I would appreciate your feedback!
1. Yes its normal. It is your brake pump priming, you will hear kind of a hum for about a second or two when idling, when you walk by the car even when it is off, or when you start it up, completely normal noise, this 2013 hybrid does it and my 2017 hybrid does it as well.
2. Yes, the brakes are ridiculous in both of my sonata hybrids, thats because you have regenerative braking for your hybrid system, which is your electric motor spinning backwards and charging the battery, also your friction braking which is your brake pads engaging, so yes, touchy brakes are normal because you have two braking sources. And 3. Your hybrid light will come on randomly if your 12v battery is low or dead. Grab a voltage tester, set it to dc, probe the battery in the trunk, anything under 11 volts means the battery is bad. And 6 years and sat for a year, your 12v battery is toast, guaranteed. Normally the light would come on right when you start the car.
248k car is currently in the dealership for a check brake warning, which we had a few years ago and we needed a $1000 part, so ill make one last video when he gets the car back and then we will probably just scrap it
