Another point, Low Battery Voltage? Are they saying the alternator is WAY to small so your battery voltage just drops as you are driving? Then you lose your braking? WTF, total BS. The tech that worked on mine always had a charger on it during system updates. That was 8 freakin months ago and standard practice. GM, is BS-ing ya all. To get mine to work, we shut off all the fun stuff, lane keep, crash avoidance, auto updates, cancel on star etc... just turn everything off possible and drive to your next favorite brand and trade in it. You and your family will be a lot safer.
