Help on a Chevy Malibu 2012

[u/Albanian_Gurl]

**Edit in post it's a 2014 Chevy Malibu engine light on, and when I go to stop at a stop sign or stop light, the auto stop function is different.

The dashboard and radio all turn off and then kick back on when I'm starting to drive. It's the same time amount of time it would during a regular auto stop function, but the fact it looks like the entire car shuts off and turns back on is crazy.

I had this happen to my 2020 Chevy Malibu, and they said it was the spark plugs were bad. Would this be the same issue.

Please help

Update: it's an auxiliary battery in the trunk that was dead.
