Battery keeps dying even after replacement. I would drive it then park it overnight and the next day it would dead. this put my safety at risk because at any time my car could die and I wouldn’t know until I sat in it. I would then have to figure out what to do next since the last 3 times it has died i was stuck with important work to do. There were no warnings or symptoms that first appeared. We have taken it to the dealership and they replaced the battery, but it has died again even after battery replacement.
