What does services esc mean on a Pontiac g6 gt 2008

esc=electronic stability control but it won't keep the vehicle from starting. Did you try to jump it?

I just got suckered into buying a 2010 g6 but not a gt ... anyways the esc is causing mine to throw off all modules transmission power steering traction eventually my voltage will begin to decrease and my transmission even tho ok starts to shift real hard do to the computer causing mixed signals ... there is no communication to the dash I was told .... I've narrowed it could be the bcm could be faulty wire could be the esc its self .... did you check all recalls and if they been fixed

Im having the same problems as sara
