I was driving to work this morning, all the dash lights came on, headlights flashing on and off, radio turning on and off, interior lights flashing, then I slowed down and got off the highway, as I turned the steering wheel it moved jumpy. I bought this car a few weeks ago and I have no idea what would cause my car to act possessed like this. Check engine light also stayed on. It seemed like it was stuck in sport mode yet it wouldn't activate it anymore.

Good afternoon,

Sounds like the battery has died and you have low voltage.

I would start by load testing the battery.

I would also check the charging system to be sure the alternator is maintaining the battery.
