I'm not sure what is really going on with my car. About once a week, my car's dash lights and nav screen blinks then the car shuts off, or almost does. It starts fine afterwards fortunately, but this past time noticed that my time/date clock had been reset as well. I have a new battery and have checked the terminals and everything seems to be fine. Also my dash temperature digital guage does not show all the lights-meaning if it is 45 degrees, the 4 is only patially lit. Any ideas?
