I had it cleared from o'reilly's since the same code was appearing on the car. I replaced the maf sensor, check engine light is still on. I-75 hills, I can no longer accelerate to maintain speeds. About 300 miles later, it came back on and the car hesitates/bucks consistently with a loss of power once the speed hits about 60 mph.

I cleaned the sensor, and the engine light went away. After these issues, I noticed the check engine light had come on for a mass air flow sensor. After this, the driver side door no longer locks electronically, I have to lock and unlock driver side door manually but the passenger side does indeed work. After this, the radio unit would at times go completely black, causing me to have to turn the car off and back on. I replaced both speakers to find out that it is possible the in-car amplifier blew.

Sometimes the car will recognize the phone, other times I have to disconnect the usb to phone connection, turn the usb cord around and reconnect a few times for the radio to recognize the phone. The issues with the electrical system started with the usb port connection to a cellular device. The cars electrical system started to have issues. This was a used pre-certified car, purchased from the dealer in which did not have any issues until its warranty was practically no longer valid.
