Starting to have the same issues only this time when the power went off and stayed off hitting the exterior fuse box did not make it come back on..., so I don’t know...tired of messing with it..

 

Same issues I went to the dealer 2 computer modules and 1300.00 later still having the same issues. This is my first and probably last Chevy no on knows what the problem is so while they gues we loose money and feel afraid to drive a car we are making payments in still !!! GM should recall this problem and fix it !!

 

Read the service GM Bulletin No.13186. GM Bulletin No. 13186. Wrong battery current sensors were installed and this could cause an incorrect reading of the battery state of charge, resulting in under charging of the battery.
