The Engine shutdown four (4) times while driving all within the first 30-days of ownership. My safety was put at risk had another vehicle been following close behind and had it failed to stop and crash into the Van. Hendrick Dodge Ram Cary, NC found 30 plus stored fault codes and I captured 2 Active Codes during two of the shutdowns (Codes U0100 and U0104. The Active Codes signify electronic communication issues. There have been no warnings signs prior to the Engine shutting down. It happens very suddenly. When the shutdowns occur, all the dashboard warning lights flash indicating that there are multiple systems failures. Hendrick Dodge has had the Van for 5 weeks and they have been unable to duplicate the shutdown so there is nothing more they are willing to do. Also escalated this to Chrysler - CASE NUMBER-[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
