2015 Dodge Charger drivetrain & axles problems

The vehicle is a marked police vehicle that was left running at the scene of an investigation. Dashboard camera video shows that approximately 14 minutes after it was parked the transmission slipped into reverse and drove off, down an embankment and into a tree. An investigation was conducted by fca and in a letter by mr. Kon of special investigations it was noted that the "inspection revealed that there was no evidence of a malfunction....".

I have taken my car to a repair shop because of a sound the car made when driving, he said it is the driveline bearing. These are non-repairable so you need to have the entire drive shaft replaced. When calling for the part it is backordered everywhere because it seems to be a consistent problem and they are a lot of people having the same problem. If this is a design problem and they must know because it is backordered everywhere why is there not a recall to fix it.
