Hey. My 2012 Chevy Sonic 1.8L AT shut everything down 2 days ago. After rolling into a parking lot and sitting for ten minutes the vehicle started like it should. Now it shuts everything down when the engine is cold and I have to wait to restart then its fine for a short drive.
Battery is good, alternator is in the process of being replaced. Battery current sensor replaced. Keyfob battery replaced. I am gonna replace the Crankshaft sensor and install the new alternator tomorrow.
BTW after it shuts down I still have dash lighting and radio just the engine won’t turn over. If anyone has any idea something I haven’t thought of…
Something I forgot to add… There was an intermittant squealing in the engine bay that I thought was the A/C compressor for a week before this all started to happen.
