my car wouldnt start two months ago, i went to BMW of manhattan, they said battery not cover whatever BS, any way, long story short, i went to another BMW, they checked the car and said everything ok, charged up the battery, it holds, so i went home

then i went to mall second week and went in for about an hour or two, came out, car wouldnt start again, i jump start then drove home, everything back to normal again, was ok for another month, then last week, around 3am, i heard alert and saw headlight and tailight flashing, after about 2 minutes, it stopped, only have the red light under rear view mirror is flashing, then i tried to start the car to check, it died again, i tried to jump from the front, didnt work, tried directly from the battery, good, it started up and Idrive showed like 10 error msgs

i dropped off at BMW today, they checked everything, starter, alternator, battery, everything ok, they told me they tried to duplicate the issue, but they couldnt and the car seems ok, asked me if i need car wash before i go home or not, i said i have time, please wash it i can wait, then they tried to start it and take it to wash, yeah, it didnt start up again, good, i was kind of happy, finally they see the issue

ok, then leave the car drive back loaner etc,
so anyone have any idea what will be the problem? they checked the batter, it holds charge, and they said they also checked the starter alternator, whatelse can be the issue?
or anyone of you had the same issue?

sounds like an electric problem.

yes, that's what i think
at the beginning, i thought the battery doesnt hold charge, but BMW tech tested it and said it does hold and looks ok
i thought maybe alternator and starter, they said ok too
i have no idea now, and they cant find the problem so far

i think maybe something is pulling the power hard
