Today…while sitting in a drive threw my 2018 equinox suddenly died. Everything in the dash started flashing and I could hear a clicking sound. I seen a low battery or battery saver message, and some break message (forget exactly what it said). Reset everything and press start, nearly started and then did the same thing. I
tried to start a minute later when the car in front moved no luck. Had to walk to the window and ask if someone could push while I steered to a parking spot…embarrassing a bit.
Sat in the parking spot for a couple minutes and tried to start again and it started. Drove back home.

Later I drove it around the neighborhood with auto stop off (L6 work around) no issues. Turned auto stop on and stopped in front of the house. The car went into auto stop and then after a few minutes of sitting there the same thing happened. Waited 5minutes and it started right up and ran fine.

so it seems if I drive with auto stop off no issues, if I have it on and I am stopped for a short period of time it dies and won’t start for a short time. Newer battery and it seems to run between 12-14.5 V.

any ideas?
any help is appreciated, thanks.

 

Those modern systems are so complicated, you really need all the help and clues you can get. Swing by an Autozone and get full diagnostic scan.

 

Your vehicle probably still has the original battery and it most likely needs to be replaced.

 

Batteries don't power vehicles. Alternators do. The battery's only job is to start the car, which it did. 🤦‍♂️

 

What was the final outcome/resolution? My fiancee has a 2018 that is doing the same thing.
