After fixing the electrical problem with the car not fully turning off, the car suddenly died in traffic and wouldn't restart. Replacing mass air sensor, O2 sensor, and plugs, the car will die in traffic when coming to a stop, but restarts immediately. The code says this is a pcm problem. Internet research says this is not uncommon resulting in safety recalls in other year models. 2013 should also be recalled.
Several months now, I'm having to turn my car back on to turn the radio off and completely shut the car down. This has been going on since the summer of this year. I have to crank it up, put it out of park into drive, and put it back in drive. After that, it turns off. I have push to start and had the car for four years pre-owned. Yesterday, my sister and I were stranded because my car didn't start. The dealership said it was the air intake oxygen sensor. They replaced it plus they put in a new car battery. My husband and I thought it was weird, but now I'm wondering if the car itself is completely shutting down when I turn it off. Now, this is making me scared to drive the car. The repair cost me 490 something.
