I have a 2006 Pontiac Vibe. Yesterday my Check Engine light came on while driving. It’s done this before and randomly gone away. My car has been in the shop twice in the past month for routine maintenance and no issues have been found.
The light annoys me, so I disconnected the battery and reconnected it a few minutes later. The car wouldn’t start. I jumped it. It started, I let it idle, turned it off, and it’s dead again. I did the same once more. Still dead.
So, my family “mechanic” says I probably didn’t connect the terminals well enough, and that it might just need to be adjusted (in all fairness, I’m playing the stupid girl card here). He said worst case scenario is that I randomly need a new alternator (I doubt this based on the circumstances), and it’s possible I might need a new battery (I think I replaced it three years ago, but maybe I didn’t).
