NHTSA Complaint #11560928 — 2019 GMC TERRAIN

It began with showing "Service Brake Assist" for about 2 weeks + then on Dec 18th 2023 around 10:30 as my fiancé was stopped at a stoplight and all of sudden when the light turned green she attempted to continue forward as traffic started to move only to stall stalled out before any movement could be achieve the battery was reading severely depleted and the vehicle would not function at all she was stuck in Drive and could not put the vehicle in neutral or even park to even try to restart the vehicle, she could not even turn the steering wheel, roll down the windows, open the door, or anything. the only thing she was able to accomplish was opening the hood so an officer that had arrived at this time could give her a jump, The officer also proceeded to leave the negative cable on the battery terminal and disconnected the Positive cable from the battery terminal which would have indicated a bad starter or depleted battery when the positive cable had been removed, which was not the case. she continued to where her appointment was and that is where i met her and took over vehicle to transport it home, driving with hazards on. I arrived at the house with no incident. then at 4:45pm on the evening of 12/18/2023 while at the stoplight I had a similar issue occurred as i was going from a stationary position to a forward slowly accelerated speed gaining momentum where the vehicle wanted to stall out while i was stopped at a stoplight attempting to proceed forward. and then at around 10:20 pm while stopped at a stop sign a similar issue occurred as i was going from a stationary position to a forward slowly accelerated speed gaining momentum attempting to proceed forward. On Dec 19th 2023 around 10:00 am I test started the car by remote and it started up and then i turned it off, now it is showing that the battery is completely depleted at 1:26 pm
