Sometimes batteries have enough jucie to start your car, there is a difference between dying battery or already dead
2006 gli, lights started to flicker, and at one night when I turn them on after starting car the car was dying, and it was a battery fault. 2010 gli same thing happened and ran to a battery guy. 2016 altis cvti two weeks back I started noticed flickering lights, and one cell was dead.
I’m 70% sure that its a battery issue.
Even I faced problem in a battery once when it was just 2months old. 2 cells weren’t charging properly. Claimed it under warranty later on.
