Had service engine light coming on periodically and was loosing coolant, but could not find any leaks, was told it was probably faulty light, or leak in tank. Took car for oil change and ask to look for any leaks, found coolant in oil. Intake manifold gasket failed and had to be replaced. Was told due to coolant being dexcool and eats the gaskets.

My 2002 buick century developed a problem with the following lights coming on - service engine light, anti lock. I had the car at my local buick dealer and repairs was made to the right front wheel. This work was done under warrunty. I had to make several trips back to the dealer to get the lights stopped from coming on, now the lights are coming on again and it is very annoying. The problem started last may 2003. It was corrected around august 2003 now in april 2004 it is starting again. I have no idea if I am having brake problems with these lights intermittently coming on. They are constantly coming on in damp weather.
