My friend's 2015 Hyundai Sonata (2.4 GDI engine) was idling in the parking lot, and the (student) driver accidentally floored the accelerator (while the vehicle was in park).
Shortly thereafter (though I don't know exactly how long, probably around a minute), the engine died and cannot be restarted.
The battery is fully charged, and my friend had AAA try jumpstarting it anyway in case the battery was too weak, with no result.
When the key is turned to the Start position, all the lights and electronics shut off (as I believe they are supposed to do), and we can hear the starter engage. Watching the belts, it looks like the engine turns 1-2 degrees, then stops.
I checked with a scan tool and the only code I found was a pending P2122 (low voltage in the throttle position sensor), which I assume was only because the engine was not running.
Thinking their might be some physical damage to the engine, I asked her what it sounded like when it shut off (if there was a bang, pop, or other loud noise), and she said that it shut off so quietly that she didn't initially realize it had turned off.
What could be wrong with this car? What should I have my friend try next?
