Vehicle was running with the driver side door open and driver out of vehicle. The vehicle slipped out of gear and reversed quickly. Driver went to get back in while moving backwards to try and stop vehicle. The driver got smashed between the garage and vehicle door. The vehicle door hyperextended and caused damage/injury to driver. The emergency brake did not come on until after the accident. Prior to this happening recalls were not preformed due to GM advising us that our vehicle was not next to get it done. Throughout ownership the vehicle has slipped out of gear two other times. We took it in each time and were told it shouldnât happen again and they could not replicate. GM did an inspection after and fixed recalls and told us they would not assist us with damage or any compensation.
