While waiting at a stop light within a mile from my house, the same issue occurred again, “Service Charging System” error followed by two additional alternating notification on the dash, “Service Shifter” error and “Service Shifter Stop Safely Shut Off Vehicle to Engage Park,” with the transmission indicator selector knob lost illumination and became non-responsive.
