NHTSA Complaint #11555405 — 2014 CHEVROLET MALIBU

No incident has occurred, thankfully. Car was purchased used in January 2018. It is now approximately about 9 years old. This issue happens intermittently but the electrical systems seem to be misfiring. Basically, it gives false negatives/positives. (1) The check engine comes on and off all the time even after servicing the vehicle with the mechanic. (2) The passenger seat has front airbags that get activated when someone sits in the seat. Lately, the seatbelt alert goes off while nothing heavy is in the seat. I have to latch the seatbelt to get that alert to stop. (3) The automatic lights that come on when you open the door sometimes don't turn on and the auto lights indicator is on. (4) Lately, when I have turned off the engine and opened the door, the radio won't turn off even after I have removed the keys. Electrical malfunctions could be happening due to the wrong wires being installed or something and may cause the car not to work any longer. I'm not sure but I don't want to encounter issues while I'm driving.
