My son's 03 GC has it's display showing problems where there are none. For example, the overhead message center shows a low coolant warning. I had a switch replaced after the vehicle was overheating about a year ago but have not had a problem since. On the dashboard, the parking brake light as well as the ABS lights stay lit at all times (while the car is started). None of these things hinder the performance of the car, it's just annoying. Also, if I ever want to sell it, I would like to not have these things popping up.
