Car Accelerates On Its Own problems of the 2010 Dodge Journey

2010 Dodge Journey - on July 8, 2019 my wife stopped at a local station for gas but when she pulled out of the station she lost all dashboard lights. The radio was playing but the controls were not working to turn the radio down or off. She decided that since the vehicle seemed to be running okay she would continue to her next stop. When she arrived at her next stop she pulled into a parking spot. All dash lights etc were still off. While depressing the brake and attempting to place the car in park the rpm's increased dramatically and she lunged forward and crashed into the building. The air bag did not deploy and the headlights were not damaged. However give the damaged cased by the fallen debris and some under carriage damage the car was determined a total loss. Since there were no recalls for the sudden acceleration problem there seem to be no interest on the part of the Chrysler dealer or my insurance agent to investigate the crash any further.
