After hitting a deer, the body shop fixed the damage to the front part of the vehicle. They realized the battery kept being drained even after purchasing a new one. Itâs now at a dealership and they are staying it needs a new ONSTAR module, not sure when it will come in either. Iâm paying for a rent car that I canât afford to pay for anymore. I wanted them to just do away with the ONSTAR but they said itâs not possible.
