I have a 13' LT hatch. Auto with the 1.8. Currently at about 122 thousand miles. I have the check engine light on on the dash which Onstar says could be an O2 sensor? My odometer stopped showing up about last year after a new battery was put in, and just recently in the last few weeks the engine overheat light came on twice on 2 separate occasions.
I checked my coolant levels and I have to keep putting coolant in, but I never see any leak, though I can smell when the car has been driven as if there is coolant leaking somewhere. This has also coincided with my heater not getting warm anymore and my air occasionally not blowing that cold.
Could the coolant and overheating issue be tied to me have to keep put coolant in? Also could the computer need a flash from the dealer in order to get the odo to show back up?
