So it was happened back in end of winter or beginning of last spring, then never happens again during warm morning weather (it's happened only on cool mornings like less then 55F). It came back a week ago as temp was around 48 and today as temp at 50F. So is anyone has same problem?
The dealer had replaced both active bars, battery is year old, and I don?t have any electrical problem (knock on wood).

I found this DIY:

Well today dealer told they saw voltage spike on alternator. So the question is could it be? I don't want replace alternator because I'm out of extended warranty so my warranty will be pay for that but it has 200 bucks deduction.
