This morning when I got into my car I had a malfunction message saying my parking brake was not working or not able to turn off. I did the two button reset however now I noticed that my back up camera is not working, neither is my gps is frozen, lines and other objects not showing up on the virtual display and finally there is a load humming noise coming from the car? Any ideas? I have done the two button and brake pedal reset and not luck. I tried turning the car off in the service option however I don't think it turns off because the noise never stops. Please help.
