Suddenly, all my gadgets--except for the mileage gadget--are set at zero. I cannot tell how much gasoline my car has or if it is overheating. Can someone tell me why this happened? Do I need to go to a dealership? Thank you.
Take the car to your local dealer(not the big dealership). There might be some glitch in the system. If the person says that there is a major problem, than it would be better to go to the main dealership. Sometimes the solution is to just reset the gages.
