NHTSA Complaint #11561671 — 2016 JEEP CHEROKEE

My parking brake suddenly turned on and my jeeps information center on the dash informed me to stop and shift to park. The light on the switch for the emergency brake flashes as well as the red light on the shifter and the vehicle would not shift anymore nor would the epb turn off . I had to disconnect my battery for about 30 minutes before it allowed me to disengage the parking brake and start to drive again. It happened again once or twice before it completely just stopped engaging even when I tried to engage it. Car states when attempting to engage the parking brake that the parking brake needs to be maintained the light on the switch flashes and a warning light stays on now. The odometer started flashing a day or so after the initial issue began. Now I am unable to use my parking break at all, the warning light and message to get parking brake serviced show constantly as well and the odometer continues to flash.
