2017 GMC Acadia drivetrain & axles problems

Tl* the contact owns a 2017 GMC acadia. While the vehicle was engaged in park with the engine running, it inadvertently rolled away. As a result, the occupant was struck by the door and the vehicle ran over the occupant's foot. Medical attention was required. The vehicle continued to roll away and rear ended another vehicle. A police report was not filed. The vehicle was taken to an independent mechanic where it was awaiting diagnostic testing and repairs. The dealer was not contacted.

A "shift to park" message shows up after I have already put my vehicle in park which does not allow me to turn my vehicle off completely. I have 53,500 miles on my acadia and had to have a new battery put in last week. A GMC dealership states the part to fix the shift lever is on back order but that they have heard this is a common issue with the 2017 acadia. It is frustrating that GMC is aware there is an issue and that there has been a lawsuit filed regarding this however there has not been a recall issued.
