Hi I have a Chevy Malibu 2015 LS Eco with only 55,000 miles. I recently changed the battery along with the alternator. I barely drive the car because I work from home. One morning after getting gas it started hesitating and now is throwing several codes and it starts up but cuts off after maybe 3 mins. A few codes are saying lost communication. There is a check engine light on and stabiltrack and airbag issue on my dashboard. This has been the worst car I have ever owned. Any idea if this sounds more like my computer needs resetting? I'm almost too afraid to see what the dealer will say.

All those voltage codes point to a bad connection issue. Don't dismiss a new battery being defective also, it happens, and new batteries should be put on a charger, so they get fully charged.
Every time you start the car all the systems and modules boot up and low voltage will set weird codes when they boot up. That's why battery and connections are critical as battery runs the systems until the alternator comes online to power the car.
ECM failures are not common.
Wiring diagram to locate the multiple ground points so they can be checked is a must. Battery cables need to be checked also.
